Delft, Netherlands -- July 15, 2021 -- Today Dutch startup QuantWare has launched the worlds first commercially available superconducting processor for quantum computers (QPU). This is the first time superconducting quantum processors have been available off the shelf, a development with the potential to significantly accelerate the quantum computing revolution.

Quantum technology promises to significantly expand the amount of data computers are able to process, which could have huge implications for fields such as A.I., medicine, business intelligence, and cybersecurity. But the quantum industry is still young and scaling is difficult. Companies building parts for quantum computers need qubits, the microscopic objects that make quantum computing possible, but it is often cost prohibitive for them to produce them themselves. QuantWares superconducting QPUs eliminate that barrier and may be instrumental in accelerating the development of the quantum computer market.

Superconducting is the leading and most mature approach to quantum processors - Google achieved quantum supremacy in 2019 using superconducting QPUs. While other QPUs are already available off the shelf, this is the first time a superconducting QPU has been easily available in productised form, leveling the playing field for quantum experimentation.

QuantWares proprietary product, Soprano, is a 5-qubit QPU. In an article published by Ars Technica, QuantWare shared that the fidelities of each qubit will be 99.9 percent, which should keep the error rate manageable. 5 qubits is sufficient for the immediate customer base QuantWare expects to attract, namely research institutions and university labs.

The race towards useful Quantum Computation is heating up, but still reserved to a small group of companies. By making QPUs more available, we will speed up the development of practical quantum-driven solutions to the worlds biggest problems. said QuantWare co-founder Dr. Alessandro Bruno.

Another way to achieve Quantum Advantage is by designing a chip specifically for a particular application. The startup wants to exploit this by making co-designed QPUs together with software companies to allow them to develop processors specialized in their algorithms.

QuantWare was founded in 2020 by quantum engineer Dr. Alessandro Bruno and Delft University of Technology (TU Delft) graduate MSc Matthijs Rijlaarsdam. They met while doing research at QuTech, a quantum technology research institute at TU Delft in the Netherlands. The company recently closed their pre-seed funding round, meaning the company has now raised 1.15M. They plan to quickly expand their team and upgrade their processors towards higher qubit numbers. One of their growth goals for the rest of the year is to expand fabrication capabilities and partnerships - QuantWare hopes to become a collaborative bridge between quantum companies worldwide. The company is already looking for new operational facilities, as they expect to outgrow their current building within months. QuantWares first two products, Crescendo and Soprano, are now available for pre-order.

A team of physicists at the Harvard MIT Ultra-Cryogenic Atomic Center and other universities have developed a special type of quantum computer known as a programmable quantum simulator that can operate at 256 qubits or qubits.

The system sheds light on the host of complex quantum processes, ultimately helping to bring real-world breakthroughs in materials science, communications technology, finance, and many other areas. It shows a big step towards building. Overcome research hurdles beyond the capabilities of todays fastest supercomputers. Qubits are the basic building blocks of quantum computers and are the source of their enormous processing power.

This moves the field to a new territory that no one has ever been to, said Mikhail Lukin, a professor of physics at George Vasmer Leverett, co-director of the Harvard Quantum Initiative and one of the senior authors of the study. Stated.Published in the journal today Nature.. We are entering a whole new part of the quantum world.

According to Sepehr Ebadi, a physics student at the Graduate School of Arts and Sciences at Harvard and the lead author of the study, the unprecedented combination of size and programmability of the system is at the forefront of the quantum computer competition. The mysterious nature of the substance on a very small scale greatly improves its processing power. Under the right circumstances, increasing the cue bit means that the system can store and process more information exponentially than the traditional bits on which a standard computer runs.

The number of quantum states possible with just 256 qubits exceeds the number of atoms in the solar system, Evadi explained the vast size of the system.

Already, the simulator allows researchers to observe some exotic quantum states that have never been experimentally realized, and is accurate enough to serve as an example in a textbook showing how magnetism works at the quantum level. Quantum phase transition research can be performed.

These experiments provide powerful insights into the quantum physics that underlie material properties and help scientists show how to design new materials with exotic properties.

The project uses a significantly upgraded version of the platform developed by researchers in 2017 that was able to reach a size of 51 qubits. The old system allowed researchers to capture ultra-low temperature rubidium atoms and place them in a particular order using a one-dimensional array of individually focused laser beams called optical tweezers.

This new system allows atoms to be assembled into a two-dimensional array of optical tweezers. This increases the achievable system size from 51 qubits to 256 qubits. Tweezers allow researchers to arrange atoms in a defect-free pattern and create programmable shapes such as squares, honeycombs, or triangular grids to design different interactions between cubits.

The flagship product of this new platform is a device called the Spatial Light Modulator, which is used to form the light wave front and generate hundreds of individually focused optical tweezers beams, Ebadi said. Mr. says. These devices are essentially the same as those used in computer projectors to display images on the screen, but we have adapted them as an important component of quantum simulators.

The initial loading of atoms into optical tweezers is random, and researchers need to move the atoms to place them in the shape of the target. Researchers use a second set of moving optical tweezers to drag the atom to the desired position, eliminating the initial randomness. Lasers give researchers complete control over the placement of atomic cubits and their coherent quantum manipulation.

Other senior authors of this study include Professors Svil Sachidef and Marcus Greiner of Harvard University, Stanford University, University of California Berkeley, and Insbrook University of Austria, who worked on the project with Professor Vladin Vretti of Massachusetts Institute of Technology. Includes scientists. Austrian Academy of Sciences and QuEra Computing Inc. in Boston.

Our work is part of a very fierce, highly visible global competition to build larger, better quantum computers, said Harvard University Physics Researcher. Tout Wang, one of the authors of the paper, said. Overall effort [beyond our own] There are leading academic research institutes involved and major private sector investments from Google, IBM, Amazon, and many others.

Researchers are currently working on improving the system by improving laser control over qubits and making the system more programmable. They are also actively exploring how systems can be used in new applications, from exploring the exotic forms of quantum materials to solving challenging real-world problems that can be naturally encoded into qubits. doing.

This study enables a huge number of new scientific directions, Evadi said. We are far from the limits of what we can do with these systems.

Among the most promising applications of quantum computing, quantum machine learning is set to form waves. But how this could be achieved is still a bit of a mystery.

IBM researchers now claim to have mathematically proven it With a quantum approach, some machine learning problems can be solved faster than conventional computers.

Machine learning is a well-established branch of artificial intelligence, and it is already used in many industries to solve different problems. This involves training an algorithm with large data sets, in order to allow the model to identify different patterns and ultimately calculate the best answer when new information is provided.

With larger data sets, a machine learning algorithm can be improved to provide more accurate answers, but this comes at a computational cost that quickly reaches the limits of traditional hardware. Thats why researchers hope that one day they will be able to harness the enormous computing power of quantum techniques to take machine learning models to the next level.

One method in particular, called quantum nuclei, is the subject of many research articles. In this approach, a quantum computer intervenes only for part of the global algorithm, by expanding the so-called characteristic space, that is, the set of properties used to characterize the data submitted to the model, such as gender or age if the system is trained to recognize patterns in people.

To put it simply, using a quantum nucleus approach, a quantum computer can distinguish between a larger number of features and thus identify patterns even in a huge database, whereas a classical computer would not see just random noise.

IBM researchers set out to use this approach to solve a specific type of machine learning problem called classification. As the IBM team explains, the most common example of a classification problem is a computer that receives pictures of dogs and cats and needs to be trained with this data set. The ultimate goal is to allow it to automatically tag all future images it receives whether it is a dog or a cat, with the goal of creating accurate tags in the least amount of time.

Big Blue scientists developed a new classification task and found that a quantum algorithm using the quantum kernel method was able to find relevant features in the data for accurate labeling, while for classical computers, the data set looked like random noise.

The routine we are using is a general method that in principle can be applied to a wide range of problems, Kristan Temme, a researcher at IBM Quantum, told ZDNet. In our research paper, we formally demonstrated that a quantum kernel estimation routine can lead to learning algorithms that, for specific problems, go beyond classical machine learning approaches.

To demonstrate the advantage of the quantum method over the classical approach, the researchers created a classification problem for which data could be generated on a classical computer, and showed that no classical algorithm could do better than a stochastic response to answer the problem.

However, when they visualized the data in a quantum feature map, the quantum algorithm was able to predict the labels very accurately and quickly.

The research team concludes, This article can be considered an important step in the field of quantum machine learning, as it demonstrates a comprehensive acceleration of a quantum nucleus method implemented in a fault-tolerant manner with realistic assumptions.

Of course, the classification task developed by scientists at IBM is specifically designed to determine whether the quantum nucleus method is useful, and is still far from ready to apply to any kind of large-scale business problem.

According to Kristan Temme, this is mainly due to the limited size of IBMs current quantum computers, which so far can only support less than 100 qubits. There are far from the thousands, if not millions, of qubits that scientists believe are necessary to start creating value in the field of quantum technologies.

At this point, we cant cite a specific use case and say this will have a direct impact, the researcher adds. We have not yet realized the implementation of a large quantum machine learning algorithm. The size of this algorithm is of course directly related to the development of quantum matter.

IBMs latest experiment also applies to a specific type of classification problem in machine learning, and it does not mean that all machine learning problems will benefit from the use of quantum cores.

But the results open the door to further research in this area, to see if other machine learning problems could benefit from using this method.

So much work is still up for debate at the moment, and the IBM team has recognized that any new discovery in this area has many caveats. But until quantum hardware improves, researchers are committed to continuing to prove the value of quantum algorithms, even if from a mathematical point of view.

Developers are familiar with software development on classic computers. Intuitive programming languages, which are based on familiar thought and language patterns, enable even newbies to get started quickly and achieve initial success with small applications.

When programming a quantum computer, the situation is more complicated and significantly more abstract due to the underlying laws of quantum mechanics. The differences between programming on a classical and a quantum computer should be illustrated by an example.

Quantum computing: this is how quantum programming works using the example of random walk - Market Research Telecast

The company's 100-qubit gate-based quantum computer, code-named Hilbert, is launching later this year after final tuning and optimization work.

By cooling atoms down to near absolute zero and then controlling them with lasers, a company has successfully created a 100-qubit quantum processor that compares to the systems developed by leading quantum players to date.

ColdQuanta, a US-based company that specializes in the manipulation of cold atoms, unveiled the new quantum processor unit, which will form the basis of the company's 100-qubit gate-based quantum computer, code-named Hilbert, launching later this year after final tuning and optimization work.

There are various different approaches to quantum computing, and among those that have risen to prominence in the last few years featuresuperconducting systems,trapped ions,photonic quantum computersand evensilicon spin qubits.

SEE: Building the bionic brain (free PDF) (TechRepublic)

Cold atoms, on the other hand, haven't made waves in the quantum ecosystem so far. ColdQuanta's 100-qubit quantum processor, however, could seemingly compete against the industry's highest standards: for example, IBM's current quantum system, Hummingbird, supports 65 qubits.

And in the next three years, ColdQuanta is hoping to create a system surpassing 1,000 qubits. This again aligns with IBM's roadmap for quantum hardware,which should see the company releasing a 1,121-qubit quantum computer in 2023.

"We hear a lot about superconducting and trapped ions and in some respects cold atom is the new kid on the block, but we believe it has great promise in terms of scalability," Paul Lipman, president of quantum computing at ColdQuanta, tells ZDNet.

ColdQuanta's approach consists of treating atoms like qubits, and bringing them down to extremely cold temperatures, where their quantum properties can be manipulated with great precision. This is because, in such an isolated environment, atoms are protected from environmental noise and can retain their quantum properties for much longer.

Cooling down particles to exert better control over them is not new to the quantum world: Google and IBM's superconducting processors also require placing qubits in huge dilution refrigerators, where temperatures are brought down to zero kelvin (-273.15C).

But ColdQuanta's cold atoms approach goes one step further. Atoms are cooled down to the microkelvin level that is, a thousand times colder than in the superconducting method.

Rather than using large refrigerators, however, ColdQuanta traps the atoms with lasers to cool them down, before using a combination of lasers and microwave pulses to arrange them into the gates that make up a quantum circuit.

"Because we cool them down with lasers rather than dilution refrigerators, we don't have the same scaling challenges in terms of building enormous fridges that can hold large numbers of qubits," says Lipman. "We cool them down to microkelvin, but we do that in a device that can fit in your hand at room temperature."

What's more: atoms are ten-thousand times smaller than superconducting qubits, according to Lipman, meaning that many cold atom qubits can be packed closely together on a much smaller space. What would require square-meters worth of space for a superconducting quantum processor can sit on a cold atom system the size of a nail, according to the company.

"Cold atoms have this intrinsic scalability that is very attractive," argues Lipman.

Cold atoms' ability to scale rapidly is one of ColdQuanta's key selling points, but there remain some engineering challenges that, for now, still limit Hilbert's size. The company's scientists are looking at how the use of lasers changes when the qubit count increases by orders of magnitude, for instance, and testbeds are already underway in the lab to determine the best path forward.

The fundamental principles of the approach, however, are tested and proven, says Lipman, and cold atoms already perform similarly to leading-edge quantum processors. Not only on qubit count: the company's data also shows thatthe system is comparable to IBM and Google's quantum computerswhen it comes to connectivity, which refers to the number of qubits that can interact with one another, and coherence, which is the duration of time that quantum properties can be maintained.

On fidelity, however, the processor lags slightly behind the devices developed by competitors, meaning that the accuracy of ColdQuanta's system isn't as high. But part of the optimization work going on now, says Lipman, is dedicated to boosting Hilbert's performance on fidelity.

Lipman is confident that these promising results will set ColdQuanta apart in an ecosystem that is growing at pace. New milestones are announced by quantum companies large and small at a rapid pace, and the number of approaches to quantum computing is multiplying fast, each with their own benefits and challenges making it increasingly difficult to distinguish hype from reality.

"It's too early to tell which modality will win the race," admits Lipman. "If you roll the clock forward two or three years, there might even be modalities that we don't even have publicly available information on today, but may come to the forefront."

"We'll learn more once the computer is released, but our focus now is to work with potential customers to deliver tangible near-term value."

ColdQuanta has not publicly announced any customers yet, but the company is working particularly on optimization problems, which could find applications in logistics, material science and telecommunications.

The firm also has a long-standing partnership with the Defense Advanced Research Projects Agency (DARPA), which awarded ColdQuanta a total $7.4 million to develop a scalable cold-atom-based quantum computer for defense applications such as resource allocation, logistics, and image recognition.

Hilbert is expected to launch later this year and will be available over ColdQuanta's private cloud. The company is also in talks with Amazon, Microsoft and Google to eventually make the quantum computer accessible over AWS, Azure and Google Cloud.
