A novel protocol for quantum computers could reproduce the complex dynamics of quantum materials.

RIKEN researchers have created a hybrid quantum-computational algorithm that can efficiently calculate atomic-level interactions in complex materials. This innovation enables the use of smaller quantum computers or conventional ones to study condensed-matter physics and quantum chemistry, paving the way for new discoveries in these fields.

A quantum-computational algorithm that could be used to efficiently and accurately calculate atomic-level interactions in complex materials has been developed by RIKEN researchers. It has the potential to bring an unprecedented level of understanding to condensed-matter physics and quantum chemistryan application of quantum computers first proposed by the brilliant physicist Richard Feynman in 1981.

Quantum computers bring the promise of enhanced number-crunching power and the ability to crack problems that are out of the reach of conventional computers.

Qubits, the building blocks of quantum computers, are essentially tiny systemsnanocrystals or superconducting circuits, for examplegoverned by the laws of quantum physics. Unlike bits used in conventional computers, which can be either one or zero, qubits can have multiple values simultaneously. It is this property of qubits that gives quantum computers their advantage in terms of speed.

An unconventional way of computation also requires a new perspective on how to efficiently process data in order to tackle problems too difficult for conventional computers.

One notable example of this is the so-called time-evolution operator. Time-evolution operators are huge grids of numbers that describe the complex behaviors of quantum materials, explains Kaoru Mizuta of the RIKEN Center for Quantum Computing. Theyre of great importance because they give quantum computers a very practical applicationbetter understanding quantum chemistry and the physics of solids.

The prototype quantum computers demonstrated to date have achieved time-evolution operators using a relatively simple technique called Trotterization. But Trotterization is thought to be unsuitable for the quantum computers of the future because it requires a huge number of quantum gates and thus a lot of computational time. Consequently, researchers have been striving to create quantum algorithms for accurate quantum simulations that use fewer quantum gates.

Now, Mizuta, working with colleagues from across Japan, has proposed a much more efficient and practical algorithm. A hybrid of quantum and classical methods, it can compile time-evolution operators at a lower computational cost, enabling it to be executed on small quantum computers, or even conventional ones.

We have established a new protocol for constructing quantum circuits that efficiently and accurately reproduce time-evolution operators on quantum computers, explains Mizuta. By combining small quantum algorithms with the fundamental laws of quantum dynamics, our protocol succeeds in designing quantum circuits for replicating large-scale quantum materials, but with simpler quantum computers.

Mizuta and his team next intend to clarify how the time-evolution operators optimized by their method can be applied to various quantum algorithms that can compute the properties of quantum materials. We anticipate that this work will demonstrate the potential of using smaller quantum computers to study physics and chemistry.

The company's dedicated research team has been actively involved in the development of both quantum computing hardware and software. In August 2022, Baidu, Inc. (NASDAQ:BIDU) introduced its first superconducting quantum computer, demonstrating its progress in integrating hardware, software, and applications. Additionally, Baidu, Inc. (NASDAQ:BIDU) has pioneered the development of a comprehensive quantum hardware-software integration solution, enabling access to a wide range of quantum chips through various platforms such as cloud services, mobile applications, and personal computers.

Here's what Horos Asset Management said about Baidu, Inc. (NASDAQ:BIDU) in its Q4 2022 investor letter:

As I mentioned at the beginning of this quarterly letter, we took advantage of the meltdown in technology platforms to initiate new positions in companies in which we had already been shareholders in the past and whose valuation did not, until now, provide a sufficiently high margin of safety. Such is the case of PayPal and Baidu, Inc.(NASDAQ:BIDU).

In the case of Baidu, as many will know, it is known as the Chinese Google. The company has been the leading Internet search engine in the Asian country for years, which has given it a historically privileged position to monetize, through online advertising, a huge user base. However, the rise of two types of applications has called into question the sustainability of its business model. On the one hand, mobile social apps, such as ByteDances well-known TikTok, have emerged as a new model of online consumption, generating a new platform through which to monetize Internet users. On the other hand, even more disruptive in the long term, is the emergence of the so-called super apps: a sort of virtual Swiss Army knives that allow users to access many products and services without having to leave their interface at any time, making Baidus traditional search engine less attractive. In this field, Tencent (with its super app Weixin/WeChat), Alibaba (Alipay) and Meituan certainly stand out. These two factors have caused Baidus online advertising market share to drop from 17% in 2017 to less than 7% estimated for 2022.34 To this deterioration, we should add the collapse in market value of its stake in iQiyi (video platform controlled by Baidu) and its equity holdings such as Trip.com (hotel and flight platform) (Click here to read the full text)

Market Capitalization: $115.29 billion

2022 Total Revenue: $60.53 billion

The hybrid quantum computing system integrates high-performance computing (HPC) infrastructure with native quantum computing technology an exciting and challenging innovation for the industry.

The research team consisting of QMware GmbH, Saint Gallen, Switzerland, and QuiX Quantum NV, Enschede, Netherlands expects it will be fully operational for commercial applications in August this year.

Hybrid quantum computing is an industry game changer.

A hybrid quantum computing system is one that combines elements of quantum computing, especially the use of quantum bits or qubits for processing, and classic computers as we know them.

Working together, quantum and classical can perform functions that are difficult or impossible for a classical computer, even supercomputers, to do alone. They also allow users to read out the results of quantum computation via their classical systems.

By combining classical high-performance computing with quantum computing, businesses can tackle todays toughest challenges in optimisation, simulation, and Machine Learning.

It has the potential to solve complex optimisation problems in a fraction of the usual time for challenges like route planning in logistics or collateral portfolio and risk optimisation in financial services.

Moreover, hybrid computing can also help simulate physical systems with extreme accuracy, which can have implications for drug discovery or materials science.

In the field of Machine Learning, it can improve classification, clustering, and regression tasks.

QMware offers a unique hybrid approach to quantum hybrid computing through its software framework.

This will be used to integrate different hardware types with shared memory access and will be operated under a unified Linux operating system. The companies say this will be the first of a new kind of data centre, which aims to increase processing power by ten-fold.

QuiX Quantum uses photonic qubits that operate at room temperature. This interesting process provides a scalable technology for optimisation applications, such as route planning and payload optimisation in logistics or aerospace, or collateral portfolio and risk control in finance.

QMware will use a broadband, low-latency optical fibre connection. This connection directly attaches high-performance computing infrastructure with simulated and native quantum hardware.

We believe that the photonics quantum processing units by QuiX Quantum, integrated into QMwares hybrid quantum high-performance computers, are one of the most promising technologies to provide a commercially sustainable hybrid computing advantage, said George Gesek, CTO and co-founder of QMware.

You may be one of those waiting for the quantum computer, the arrival of which we have been told is imminent for several years. Already at this point, DTU Associate Professor Sven Karlsson begins to look a little strained, because among his partners are the two European companies AQT and IQM which produce and sell quantum computers.

"It's a common misconception that the quantum computer doesn't exist yet. It does already exist, so it's not something we need to wait for. However, the current quantum computers aren't yet all that large, which obviously limits how complicated the calculations can be, but they exist and are being used," says Sven Karlsson.

One example is IBM's quantum computers, which anyone can access via the internet. In addition, there are quantum computers in scientific laboratories, in supercomputer centers, at universities, and so onworldwide. These are also among the customers to which AQT and IQM sell their products.

It has not yet been possible to build quantum computers with many quantum bits. Quantum bits are used to process the information in the computer, and a low number of quantum bits therefore limits the complexity of the calculations the quantum computer can perform. Sven Karlsson therefore characterizes the current use as primarily experimental, making it possible to play with and understand the technology.

"The technical level of the current quantum computers is somewhat similar to the first stage of our current computers. When they first appeared in the 1950s, there were only a limited number of them, and, back then, they couldn't make larger calculations than those any calculator can perform today."

However, there are examples of calculations performed using a quantum computer. One of the calculations known to Sven Karlsson was done during the coronavirus pandemic. The Italian football league needed to know how best to schedule the matches so that the different football teams came into contact with each other as little as possible to reduce the risk of infection. Likewise, travel distances for the players had to be limited, as travel by air was banned.

"A quantum computer is well suited for calculations of this type that will take too long for an ordinary supercomputer. The quantum computer can examine many solutions simultaneously and is therefore more efficient at such calculations than a supercomputer," says Sven Karlsson.

Sven Karlsson and his colleagues' collaboration with AQT and IQM includes developing the hardware and software needed to connect the quantum computer to supercomputers.

"The future quantum computers will initially largely be connected to the relatively few high-performance computing centers with supercomputers that exist worldwide. The centers have already built an infrastructure with the right competences to operate the quantum computers, and it also makes sense to invest in relation to the existing centers. Today, a quantum computer costs around DKK 150 million, so it's a relatively large investment," says Sven Karlsson.

The quantum computer will not replace supercomputers. Instead, it will supplement them and be used for highly specific calculations. Nor will the quantum computer have its own user interface, but must be accessed via the supercomputers.

As a result of the current budding production of quantum computers worldwide, large-scale standardization work is being initiated. It includes standards for all the hardware and software parts that make up a quantum computer. The hope is to prevent inexpediencies that we struggle with in other technological areas, such as only being able to use one charger type for our mobile phone.

"We would like to develop joint standards so that, throughout the world, we have the same understanding and use of the different components that make up a quantum computer. This must be done already at this early stage, so that we don't risk individual countries or parts of the world introducing different standards," says Sven Karlsson.

Sven Karlsson leads a group of researchers and practitioners with in-depth experience with and knowledge of quantum computers, who will meet in the coming years to create recognized standards that can be used in future production.
