Many researchers believe that quantum computers will complement rather than replace our conventional technologies. Some researchers have expressed skepticism that scalable quantum computers could ever be built, typically because of the issue of maintaining coherence at large scales, but also for other reasons. As described by the threshold theorem, if the error rate is small enough, it is thought to be possible to use quantum error correction to suppress errors and decoherence.

Better understanding and working to solve these challenges is why Atom Computing is chasing scale at the same time as error-correction. In addition to error-correction in neutral atom quantum computers, IBM announced this year they’ve developed error correction codes for quantum computing that could reduce the number of necessary qubits needed by an order of magnitude. In a real quantum computer, qubits can be represented by various physical systems, such as electrons with spin, photons with polarization, trapped ions, and semiconducting circuits. With the ability to perform complex operations exponentially faster, quantum computers have the potential to revolutionize many industries and solve problems that were previously thought impossible. The most famous example is Peter Shor’s beautiful quantum factoring algorithm. To find the prime factors of an nnn-bit integer seems to be a very difficult problem on a classical computer.

Key SLURM functions include job queuing and prioritization, virtualization, resource allocation with node selection and reservation capabilities, and intricate workload management through job arrays and task distribution. SLURM also offers real-time monitoring, reporting, access control and accounting features. As quantum computers will work alongside classical HPCs, a way to increase efficiency would be to split computational tasks between the HPC and quantum systems using SLURM. For optimal integration into such HPC environments, quantum computers should also possess a SLURM interface. Application Programming Interfaces (APIs) and Software Development Kits (SDKs) are essential for developers to integrate quantum computing capabilities into existing applications.

Quantum algorithms take a new approach to these sorts of complex problems — creating multidimensional computational spaces. This turns out to be a much more efficient way of solving complex problems like chemical simulations. Computer engineers typically describe a modern computer’s operation in terms of classical electrodynamics. Within these “classical” computers, some components (such as semiconductors and random number generators) may rely on quantum behavior, but these components are not isolated from their environment, so any quantum information quickly decoheres. While programmers may depend on probability theory when designing a randomized algorithm, quantum mechanical notions like superposition and interference are largely irrelevant for program analysis. Quantum computers mimic the behavior of atoms and subatomic particles to drastically increase processing speed.

Some types of anyons can be used to make what are called “topologically protected” qubits, which are stable against any small, local disturbances. The Wellcome Trust has selected the Cleveland Clinic-IBM Discovery Accelerator to develop proof-of-concept demonstrations of quantum computing for biologic and health applications through the Wellcome Leap Quantum for Bio Challenge. The complex mathematics behind these unsettled states of entangled ‘spinning coins’ can be plugged into special algorithms to make short work of problems that would take a classical computer a long time to work out… if they could ever calculate them at all.

A team led by scientists and engineers at the University of Washington has announced a significant advancement in this quest. In a pair of papers published June 14 in Nature and June 22 in Science, they report that, in experiments with flakes of semiconductor materials — each only a single layer of atoms thick — they detected signatures of “fractional quantum anomalous Hall” (FQAH) states. The team’s discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons — strange “quasiparticles” that have only a fraction of an electron’s charge.

And if it didn’t work—and often, it didn’t—they had to redesign and build it again. We made these early bets because we believed—and still do—that quantum computing can accelerate solutions for some of the world’s most pressing problems, from climate change to disease. Given that nature behaves quantum mechanically, quantum computing gives us the best possible chance of understanding and simulating the natural world at the molecular level. With this breakthrough we’re now one step closer to applying quantum computing to—for example—design more efficient batteries, create fertilizer using less energy, and figure out what molecules might make effective medicines. As well as superposition, quantum particles also exhibit another strange behaviour called entanglement which also makes this tech so potentially ground-breaking.

Quantum Computing Initiatives

This contributed commentary from Yuval Boger and Yoel Knoll is a bit on the skeletal side, but it also broadly notes many of the important considerations that potential users of quantum computers need to consider in preparation to deploy a quantum computer. For some time, it looked like most quantum computer users would access quantum devices by a web portal. Indeed, that may still turn out to be true, but recently more quantum computer developers are talking about delivering on-premise solutions, whether embedded in a major HPC center, like Leibniz, or at a private entity as IBM has done at the Cleveland Clinic.

Here, I want to explain why the billion-dollar rush into quantum computing may not yield results for many years to come. Quantum computing refers to the use of quantum mechanics to run calculations. Quantum computing can run multiple processes at once by using quantum bits, unlike binary bits which power traditional computing. Hear from Government leaders on the UK’s commitment to the development of scalable quantum computing and the vision for getting businesses like yours ready for the tipping-point of commercialisation for this transformative technology.

What might quantum technology do?

Using lasers as probes, the researchers detected signatures of the FQAH effect, a major step forward in unlocking the power of anyons for quantum computing. FQAH states are related to the fractional quantum Hall state, an exotic phase of matter that exists in two-dimensional systems. In these states, electrical conductivity is constrained to precise fractions of a constant known as the conductance quantum. But fractional quantum Hall systems typically require massive magnetic fields to keep them stable, making them impractical for applications in quantum computing. The FQAH state has no such requirement — it is stable even “at zero magnetic field,” according to the team. For the second project, Algorithmiq joins the collaborators to create a set of computational tools that aims to explore how quantum computing could assist in the development of photon-activated drugs for cancer.

The discovery of new drugs relies in part on a field of science known as molecular simulation, which consists of modelling the way that particles interact inside a molecule to try and create a configuration that’s capable of fighting off a given disease. “It makes you optimistic that this will work in other systems and more complicated algorithms,” John Martinis, a physicist at the University of California, Santa Barbara, who achieved the 2019 Google result, told Nature News.

Using quantum computers to solve complex social issues

While technologies such as Quantum Key Distribution and Quantum Random Number Generation will lead to more secure communication and systems, the power of quantum technologies also introduces new threats to current implementations. Most cryptographic algorithms today are computationally hard, thus making them difficult to be broken in practice in a reasonable amount of time by adversaries using classical computers. However, it has been theoretically established that certain current cryptographic algorithms can be broken by a sufficiently powerful quantum computer in a matter of minutes, thus posing a major threat to current cryptography. The behavioral science paradigm sheds light on the human and organizational behavior (Bariff and Ginzberg 1982). As with every technology, quantum computing is not a universal solution to every problem that companies face. Quantum computing is likely to perform specific tasks with a considerable performance increase in comparison to traditional systems.

In the state of superposition, any arbitrary number of qubits N occupy all of their possible states at once. If we have 4 qubits, the sample will have 2⁴ possible states, but in superposition all these states will obtain simultaneously. The probability of collapsing to one of these states upon measurement will be distributed equally along the linear combination of the unit vectors. We democratise quantum computing applications for businesses by removing the need for quantum algorithms knowledge for software developers.
