Quantum computers could revolutionize the way we tackle problems that stump even the best classical computers.
Single atom transistor recently introduced has been seen as a tool that could lead the way to building a quantum computer. For general introduction how quantum computer work, read A tale of two qubits: how quantum computers work article.
D-Wave Announces Commercially Available Quantum Computer article tells that computing company D-Wave has announced that they’re selling a quantum computing system commercially, which they’re calling the D-Wave One. D-Wave system comes equipped with a 128-qubit processor that’s designed to perform discrete optimization operations. The processor uses quantum annealing to perform these operations.
D-Wave is advertisting a number of different applications for its quantum computing system, primarily in the field of artificial intelligence. According to the company, its system can handle virtually any AI application that can be translated to a Markov random field.
Learning to program the D-Wave One blog article tells that the processor in the D-Wave One – codenamed Rainier – is designed to perform a single mathematical operation called discrete optimization. It is a special purpose processor. When writing applications the D-Wave One is used only for the steps in your task that involve solving optimization problems. All the other parts of your code still run on your conventional systems of choice. Rainier solves optimization problems using quantum annealing (QA), which is a class of problem solving approaches that use quantum effects to help get better solutions, faster. Learning to program the D-Wave One is the first in a series of blog posts describing the algorithms we have run on D-Wave quantum computers, and how to use these to build interesting applications.
But is this the start of the quantum computers era? Maybe not. D-Wave Announces Commercially Available Quantum Computer article comments tell a story that this computer might not be the quantum computer you might be waiting for. It seem that the name “quantum computer” is a bit misleading for this product. There are serious controversies around the working and “quantumness” of the machine. D-Wave has been heavily criticized by some scientists in the quantum computing field. First sale for quantum computing article tells that uncertainty persists around how the impressive black monolith known as D-Wave One actually works. Computer scientists have long questioned whether D-Wave’s systems truly exploit quantum physics on their products.
Slashdot article D-Wave Announces Commercially Available Quantum Computer comments tell that this has the same central problem as before. D-Wave’s computers haven’t demonstrated that their commercial bits are entangled. There’s no way to really distinguish what they are doing from essentially classical simulated annealing. Recommended reading that is skeptical of D-Wave’s claims is much of what Scott Aaronson has wrote about them. See for example http://www.scottaaronson.com/blog/?p=639, http://www.scottaaronson.com/blog/?p=198 although interestingly after he visited D-Wave’s labs in person his views changed slightly and became slightly more sympathetic to them http://www.scottaaronson.com/blog/?p=954.
So it is hard to say if the “128 qubits” part is snake oil or for real. If the 128 “qubits” aren’t entangled at all, which means it is useless for any of the quantum algorithms that one generally thinks of. It seem that this device simply has 128 separate “qubits” that are queried individually, and is, essentially an augmented classical computer that gains a few minor advantages in some very specific algorithms (i.e. the quantum annealing algorithm) due to this qubit querying, but is otherwise indistinguishable from a really expensive classical computer for any other purpose. This has the same central problem as before: D-Wave’s computers haven’t demonstrated that their commercial bits are entangled.
Rather than constantly adding more qubits and issuing more hard-to-evaluate announcements, while leaving the scientific characterization of its devices in a state of limbo, why doesn’t D-Wave just focus all its efforts on demonstrating entanglement, or otherwise getting stronger evidence for a quantum role in the apparent speedup? There’s a reason why academic quantum computing groups focus on pushing down decoherence and demonstrating entanglement in 2, 3, or 4 qubits: because that way, at least you know that the qubits are qubits! Suppose D-Wave were marketing a classical, special-purpose, $10-million computer designed to perform simulated annealing, for 90-bit Ising spin glass problems with a certain fixed topology, somewhat better than an off-the-shelf computing cluster. Would there be even 5% of the public interest that there is now?

Quantum Circuit Uses Just A Few Atoms
https://hackaday.com/2022/06/25/quantum-circuit-uses-just-a-few-atoms/
Researchers at the University of New South Wales and a startup company, Silicon Quantum Computing, published results of their quantum dot experiments. The circuits use up to 10 carbon-based quantum dots on a silicon substrate. Metal gates control the flow of electrons. The paper appears in Nature and you can download the full paper from there.
What’s new about this is that the dots are precisely arranged to simulate an organic compound, polyacetylene. This allowed researchers to model the actual molecule. Simulating molecules is important in the study of exotic matter phases, such as superconductivity. The interaction of particles inside, for example, a crystalline structure is difficult to simulate using conventional methods. By building a model using quantum techniques on the same scale and with the same topology as the molecule in question, simulation is simplified.

Before quantum computers and quantum networks can fulfil their huge potential, scientists have got several difficult problems to overcome – but a new study outlines a potential solution to one of these problems.
Tomi Engdahl says:

Scientists create quantum computer that breaks free of binary system
https://www.independent.co.uk/tech/quantum-computer-binary-qudit-science-b2128385.html#Echobox=1658416073
Scientists have made a quantum computer that breaks free from the binary system.
Computers as we know them today rely on binary information: they operate in ones and zeroes, storing more complex information in “bits” that either off or on. That seemingly simple system is at the heart of every computer we use.
Quantum computers have taken on that same system. They use qubits, which replicate the bits of a classical computer but using quantum technology.
But they are built with more than just those ones and zeroes. Quantum computers are not necessarily restricted to binary, and scientists hope that breaking them are from that system can add extra complexity without using more quantum particles.
Now scientists say they have succeeded in building a quantum computer that works in that way. It can do calculations not with qubits but instead with qudits – quantum digits that could allow for vastly more computing power.

City College of New York physicist Pouyan Ghaemi and his research team are claiming significant progress in using quantum computers to study and predict how the state of a large number of interacting quantum particles evolves over time. This was done by developing a quantum algorithm that they run on an IBM quantum computer. “To the best of our knowledge, such particular quantum algorithm which can simulate how interacting quantum particles evolve over time has not been implemented before,” said Ghaemi, associate professor in CCNY’s Division of Science.

Quantum annealing can beat classical computing in limited cases
https://phys.org/news/2022-08-quantum-annealing-classical-limited-cases.html
Recent research proves that under certain conditions, quantum annealing computers can run algorithms—including the well-known Shor’s algorithm—more quickly than classical computers. In most cases, however, quantum annealing does not provide a speed-up compared to classical computing when time is limited, according to a study in Nature Communications.
“We proved that you can be sure you will reach a fast solution from the initial problem, but that’s only true for a certain class of problems that can be set up so that the many histories of evolution of the quantum system interfere constructively. Then the different quantum histories enhance each other’s probability to reach the solution,” said Nikolai Sinitsyn, a theoretical quantum physicist at Los Alamos National Laboratory and coauthor of the paper with his Los Alamos colleague Bin Yan.

Disentangling the Facts From the Hype of Quantum Computing IEEE Quantum Week is a chance to celebrate progress and acknowledge the challenges
https://spectrum.ieee.org/ieee-quantum-week?share_id=7228601&socialux=facebook&utm_campaign=RebelMouse&utm_content=IEEE+Spectrum&utm_medium=social&utm_source=facebook#toggle-gdpr
Few fields invite as much unbridled hype as quantum computing. Most people’s understanding of quantum physics extends to the fact that it is unpredictable, powerful, and almost existentially strange. A few years ago, I provided IEEE Spectrum an update on the state of quantum computing and looked at both the positive and negative claims across the industry. And just as back in 2019, I remain enthusiastically optimistic today. Even though the hype is real and has outpaced the actual results, much has been accomplished over the past few years.
First, let’s address the hype.
Over the past five years, there has been undeniable hype around quantum computing—hype around approaches, timelines, applications, and more. As far back as 2017, vendors were claiming the commercialization of the technology was just a couple of years away—like the announcement of a 5,000-qubit system by 2020 (which didn’t happen). There was even what I’d call antihype, with some questioning if quantum computers would materialize at all
More recently, companies have shifted their timelines from a few years to a decade, but they continue to release road maps showing commercially viable systems as early as 2029.
And these hype-fueled expectations are becoming institutionalized: The Department of Homeland Security even released a road map to protect against the threats of quantum computing, in an effort to help institutions transition to new security systems. This creates an “adopt or you’ll fall behind” mentality for both quantum-computing applications and postquantum cryptography security.
Market research firm Gartner (of the “Hype Cycle” fame) believes quantum computing may have already reached peak hype, or phase two of its five-phase growth model. This means the industry is about to enter a phase called “the trough of disillusionment.” According to McKinsey & Company, “fault tolerant quantum computing is expected between 2025 and 2030 based on announced hardware roadmaps for gate-based quantum computing players.” I believe this is not entirely realistic, as we still have a long journey to achieve quantum practicality—the point at which quantum computers can do something unique to change our lives.
In my opinion, quantum practicality is likely still 10 to 15 years away. However, progress toward that goal is not just steady; it’s accelerating. That’s the same thing we saw with Moore’s Law and semiconductor evolution: The more we discover, the faster we go. Semiconductor technology has taken decades to progress to its current state, accelerating at each turn. We expect similar advancement with quantum computing.

SCIENTISTS FED THE FIBONACCI SEQUENCE INTO A QUANTUM COMPUTER AND SOMETHING STRANGE HAPPENED
https://futurism.com/the-byte/fibonacci-quantum-computer
“YOU CAN HAVE THE SYSTEM BEHAVE AS IF THERE ARE TWO DISTINCT DIRECTIONS OF TIME.”
Future of Computing
Physicists shot a laser pulse sequence mimicking the Fibonacci sequence at a quantum computer and ended up creating a new phase of matter in the process, according to a study published in Nature earlier this year.
They suggest that the newfound phase of matter is particularly robust in preserving information, more so than the methods currently used.
In the experiment, a regular qubit at each end of a line-up of ten atoms retained its quantum state for 1.5 seconds. But when they blasted those atoms with a pulse of laser light to the tune of the Fibonacci numbers — a sequence of numbers where each number is the sum of the two preceding ones — the qubits lasted a whopping 5.5 seconds.
And according to the physicists, the reason that occurs has to do with time itself.
“What we realized is that by using quasi-periodic sequences based on the Fibonacci pattern, you can have the system behave as if there are two distinct directions of time,” study lead author Philip Dumistrescu, a research fellow at the Flatiron Institute’s Center for Computational Quantum Physics, told Gizmodo in a recent interview.
Erasing Errors
But why the Fibonacci numbers? In essence, when you shoot laser pulses following the Fibonacci numbers, they act as a sort of quasicrystal, the physicists say, a structure of matter that adheres to a pattern, but is not periodic.
In other words, ordered, but not repeating.
“With this quasi-periodic sequence, there’s a complicated evolution that cancels out all the errors that live on the edge,” Dumistrescu elaborated in a press release. “Because of that, the edge stays quantum-mechanically coherent much, much longer than you’d expect.”

And with that, the slow but steady march toward a quantum processor with real-world applications continues.
“The new 433 qubit ‘Osprey’ processor brings us a step closer to the point where quantum computers will be used to tackle previously unsolvable problems,” said Darío Gil, senior vice president, IBM and director of Research. “We are continuously scaling up and advancing our quantum technology across hardware, software and classical integration to meet the biggest challenges of our time, in conjunction with our partners and clients worldwide. This work will prove foundational for the coming era of quantum-centric supercomputing.”
