Quantum computing stands at the forefront of groundbreaking computer research today. Spearheaded by Don Towsley, a Distinguished Professor at the Manning College of Information and Computer Sciences (CICS), an interdisciplinary team at the University of Massachusetts Amherst is actively contributing to this transformative field.

The infrastructure needed to support future city-scale quantum networks is being designed by Towsley and his colleagues at UMass in the College of Engineering and CICS. This work is being managed by the Center for Quantum Networks, a $26 million, five-year, renewable project headed by the University of Arizona, one of the Engineering Research Centers of the National Science Foundation.

Compared to the bit-based computing that is performed, quantum computing is very different. A bit denotes an electrical current, either on or off, and is commonly expressed as a 0 or a 1. The software, websites, and emails that make up the electronic world are built on bits. Thousands of them make up even the most basic digital artifacts; this story, for example, has over 170,000 bits.

In contrast, quantum bits, or qubits, are the building blocks of quantum computing. They resemble regular bits but represent particles in a quantum state. Because of the drastically different behavior of matter in a quantum state, qubits are not limited to being either ones or zeroes, on or off.

Although they are not magical, Stefan Krastanov, an Assistant Professor of Information and Computer Sciences at UMass Amherst and one of the researchers contributing to the design of the quantum network, notes that their different behavior opens up a range of computing possibilities.

For many computing problems, quantum computers are no more powerful than conventional ones. However, for a growing family of important problems like drug discovery, cryptography, and scientific simulations, only quantum algorithms have a chance of providing solutions.

The ability of matter to become entangled is one of the more peculiar features of the quantum state. Here, the game of pool serves as a useful analogy. In the real world, the three-ball goes into the corner pocket when the cue ball strikes it. However, in a quantum world, the three balls might be entangled with another ball, like the eight ball, in this case, both the eight and the three would react simultaneously to the cue, even though the eight ball was not touched.

Entangling quantum computers through a quantum internet could offer unparalleled digital securitya primary focus of the Center for Quantum Networks' research, while also significantly enhancing the computing capabilities of current top-tier machines.

However, for any of this to occur, a secure quantum network that is capable of connecting quantum computers and sending entangled qubits is required.

The problem, is that quantum information- those qubits - is incredibly fragile and very sensitive to environmental noise, such as heat. This requires the careful design of a network architecture, algorithms, and protocols to protect against this noise.

Towsley is working with colleagues at UMass, including Krastanov and Assistant Professor of Information and Computer Science Filip Rozpedek, as well as Assistant Professor of Electrical and Computer Engineering Taqi Raza in the College of Engineering, to figure out how to send qubits securely without having to worry about them being lost or decaying.

This problem calls for computer science and engineering knowledge since, in the words of Raza, whose area of expertise is critical infrastructure security, Security cuts across all the various specialties that must contribute to a successful quantum network. We are working to embed security principles in quantum networks from the start.

Quantum computing is not just an advance in technology. Its a paradigm shift in how we process information. Were proud contributors to this thrilling journey to usher in the next era of computing. NSFs recognition of UMass Amherst as a key hub in the northeast amplifies our sense of pride and highlights the significant role our talented researchers play in advancing the field.

Towsley is spearheading the establishment of a UMass Amherst center of excellence to support research in quantum information systems, which will work to develop a quantum internet and provide network security to connect quantum computers, thanks to a seed fund established by anonymous donors, including a gift of $5 million.

Sanjay Raman, Dean, College of Engineering, College of Information and Computer Sciences, states, Our role as a core institution in the NSF Center for Quantum Networks is part of a broader, growing interdisciplinary initiative in quantum information systems here at UMass, involving faculty and researchers in CICS, Electrical and Computer Engineering, and Physics in the College of Natural Sciences.

Between the three colleges, we have nine core faculty in the quantum information systems area, working on everything from quantum materials, devices, and circuits to algorithms and security, and many others who are helping to explore the science and applications of the quantum world, concludes Sanjay Raman.

AMHERST, Mass. Quantum computing is one of the most potentially transformative areas of computer research happening today. Now, an interdisciplinary team at the University of Massachusetts Amherst, under the leadership of Don Towsley, Distinguished Professor in the Manning College of Information and Computer Sciences (CICS), is helping to lead the charge. Towsley and his UMass colleagues in CICS and the College of Engineering are responsible for designing the infrastructure to support future city-scale quantum networks, an effort overseen by the Center for Quantum Networks, a $26 million, five-year, renewable effort led by the University of Arizona, one of the National Science Foundations Engineering Research Centers.

Quantum computing differs fundamentally from the bit-based computing we all do every day. A bit is typically expressed as a 0 or a 1 and represents an electrical current that is either off or on. Bits are the basis for all the software, websites and emails that make up our electronic world. Even the simplest digital artifacts are composed of thousands of them: this story, for instance, contains more than 170,000 bits.

By contrast, quantum computing relies on quantum bits, or qubits, which are like regular bits except that they represent particles in a quantum state. Matter in a quantum state behaves very differently, which means that qubits arent relegated to being only 0s or 1s, off or on.

That difference in their behavior opens up a range of possibilities in computingthough they are not magical, points out Stefan Krastanov, assistant professor of information and computer sciences at UMass Amherst and one of the researchers helping to design the quantum network,. For many computing problems, quantum computers are no more powerful than conventional ones, he says. However, for a growing family of important problems like drug discovery, cryptography and scientific simulations, only quantum algorithms have a chance of providing solutions.

One of the stranger aspects of the quantum state is that matter can be entangled. The game of pool is a helpful analogy here. In our everyday world, a cue ball smacking into the three ball will send the three ball into the corner pocket. But in a quantum world, the three ball could be entangled with, say, the eight ball, and when the cue hits the three both the three and the eight will react in exactly the same way at exactly the same time, even though nothing touched the eight ball.

Entangling quantum computers over a quantum internet could provide unparalleled digital securityone of the main applications of the Center for Quantum Networks research, as well as vastly increasing the computing power of todays most powerful machines.

But for any of this to happen, there needs to be a secure quantum network that can link quantum computers and transmit entangled qubits. The problem, says Towsley, who is also director of the Quantum Information Systems Institute at UMass?, is that quantum informationthose qubitsis incredibly fragile, and very sensitive to environmental noise, such as heat. This requires the careful design of a network architecture, algorithms and protocols to protect against this noise.

Southampton to drive UK Quantum computing capability

The University of Southampton has been awarded around 32million to launch two research centres that will work to develop the future of quantum computing and boost UK defence expertise. Announced by the Engineering and Physical Sciences Research Council (EPSRC), the funding will be provided by the government, industry giants and small and medium sized enterprises along with some matching support from Southampton.

The centres intend to train PhD students to increase the talent pool of skilled innovators needed for Britains quantum technology and defence sectors.

The 18million EPSRC-funded Centre for Doctoral Training in Quantum Technology Engineering will receive funding from tech businesses including Microsoft, QinetiQ, Riverlane and Oxford Ionics.

Its directorDr Tim Freegarde from the University of Southampton, said the centre will be a crucial part of government plans to transform Britain into a quantum-enabled economy by 2033.

He added: Within 10 to twenty years, quantum technologies will be affecting our lives in diverse ways from faster mobile data and banking security to GPS-free navigation and locating pipes beneath the road.

"Our training centre will develop a new generation of graduates with the knowledge, skills and awareness needed to engineer new quantum technologies and put the UK at the forefront of the worlds quantum industry."

The two new centres opening in Southampton are among 65 announced byUK Research and Innovation (UKRI) to train 4,000 PhD students across the next 10 years.

The 12.5 million Centre for Complex Integrated Systems for Defence and Security will train the next generation of leaders and experts needed to support UK safety and resilience. It will be funded by EPSRC, the Ministry of Defence and numerous industry partners, bringing together graduates and former military and policing personnel, said centre director Professor Jordan Cheer.

A strong defence and security industry is vital for the UK, and our centre will train a new generation who will work to keep Britains future safe.

"We are opening places to graduates, current sector employers and those transitioning from serving military or policing roles to drive forward research that will develop the complex technologies needed for the modern defence and security of our country.

Experts from the University of Southampton have also been awarded funding for two additional doctoral training centres one on mathematics for the future climate, hosted at Imperial College London, and another on acoustics at the University of Salford.

If youre searching for undervalued quantum computing stocks to add to your portfolio this month, look no further. Never before in human history has technology progressed at the rate seen today. In just two decades, human civilization went from miniaturizing the computer to AI software aggregating data across the internet. With advancements in physics, humanity now harnesses the computational power of the smallest subatomic particles.

These breakthroughs enable the current state of quantum computing, where the limitations of processing hardware are pushed every single day. As a technology, however, quantum computing still has not found many mainstream applications, and thrives in the realm of research.

Yet the sheer level of investment by tech giants, such as Google (NASDAQ:GOOG, NASDAQ:GOOGL), Microsoft (NASDAQ:MSFT) and Amazon (NASDAQ:AMZN), hints at its tremendous potential. Now, for investors, the key to success lies in finding the undervalued quantum computing stocks on the market today. Here are three stocks with strong potential, competing for a share of the $42 billion future of the quantum market.

One of the best ways to assess a companys potential comes from predicting future applications of its current products. For Rigetti Computing (NASDAQ:RGTI), its focus on quantum integrated circuits means that it could become especially valuable. Thats because integrated circuits are essentially like specialized microchips, custom built to the computer they are installed on.

This approach means that Rigetti primarily focuses on developing research in hardware, software, and user interfaces for its products. As such, once Rigettis customer base grows alongside quantum computing demand, the company will have full-stack control over its products. Once customers begin rolling in, RGTI will be able to use this multi-layered approach to diversify its revenue streams.

Thanks to RGTIs early presence in quantum computing, it stands ready for a potential boom, pending breakthroughs in the field. Moreover, with its current price around $2, RGTI could be one of the most undervalued quantum computing stocks available.

Specializing in a type of sensor computing known as integrated photonics, Quantum Computing, Inc. (NASDAQ:QUBT) occupies a niche of quantum mechanics. By leveraging the quantum mechanical properties of light, QUBT has positioned itself as a premier researcher with partners such as NASA and Los Alamos.

The companys small size and short tenure make adding it to an investment portfolio a serious decision. Much of the technology the company produces targets highly specific research rather than commercial applications. Therefore, the long-term growth of this company is more tied to government interest in spending on quantum mechanics research.

For investors however, this one is worth keeping an eye on. Thats because it is one of the few companies to offer a highly specialized product in a relatively new market. Despite operational losses and lacking experience, QUBTs position could shift rapidly depending on the decisions of the U.S. government.

Perhaps one of the best undervalued quantum computing stocks on the market today, IonQ (NASDAQ:IONQ) offers multiple commercially available quantum computers. Unlike other companies that focus on using light or superconducting qubits, IonQ uses atomic ions and electromagnetism to perform calculations.

By using this form of quantum computing, IonQ offers some of the most stable and maintainable quantum computing patterns. Thus, its products are capable of solving complex calculations over extended periods of time. Furthermore, this type of quantum computing is easier to scale than others. To customers, this means products custom tailored to the needs of different projects.

The company also offers software and training specific to all of the projects mentioned above. It also maintains $456 million cash balance as of March 2024, and customers across all major cloud computing services. Bearing all of this in mind, IonQ might just be the best of the undervalued quantum computing stocks today.
