‘Giant atoms’ May Create All-in-One Quantum Processing and Communication

By Matt Swayne

MIT News reports that researchers have introduced a quantum computing architecture that can perform low-error quantum computations while also rapidly sharing quantum information between processors. The work represents a key advance toward a complete quantum computing platform.

Before, small-scale quantum processors have successfully performed tasks at a rate exponentially faster than that of classical computers. However, it has been difficult to controllably communicate quantum information between distant parts of a processor. In classical computers, wired interconnects are used to route information back and forth throughout a processor during the course of a computation. In a quantum computer, however, the information itself is quantum mechanical and fragile, requiring fundamentally new strategies to simultaneously process and communicate quantum information on a chip.

“One of the main challenges in scaling quantum computers is to enable quantum bits to interact with each other when they are not co-located,” says William Oliver, an associate professor of electrical engineering and computer science, MIT Lincoln Laboratory fellow, and associate director of the Research Laboratory for Electronics. “For example, nearest-neighbor qubits can easily interact, but how do I make ‘quantum interconnects’ that connect qubits at distant locations?”

The answer lies in going beyond conventional light-matter interactions.

China’s New Quantum Computer Has 1 Million Times the Power of Google’s

And they say it’s the world’s fastest.

By  Brad Bergan

It appears a quantum computer rivalry is growing between the U.S. and China.

Physicists in China claim they’ve constructed two quantum computers with performance speeds that outrival competitors in the U.S., debuting a superconducting machine, in addition to an even speedier one that uses light photons to obtain unprecedented results, according to a recent study published in the peer-reviewed journals Physical Review Letters and Science Bulletin.

China has exaggerated the capabilities of its technology before, but such soft spins are usually tagged to defense tech, which means this new feat could be the real deal.

A Simple Crystal Could Finally Give Us Large-Scale Quantum Computing, Scientists Say

By lenexweb

Vaccine and drug development, artificial intelligence, transport and logistics, climate science – these are all areas that stand to be transformed by the development of a full-scale quantum computer. And there has been explosive growth in quantum computing investment over the past decade.

Yet current quantum processors are relatively small in scale, with fewer than 100 qubits – the basic building blocks of a quantum computer. Bits are the smallest unit of information in computing, and the term qubits stems from “quantum bits”.

While early quantum processors have been crucial for demonstrating the potential of quantum computing, realizing globally significant applications will likely require processors with upwards of a million qubits.

Our new research tackles a core problem at the heart of scaling up quantum computers: how do we go from controlling just a few qubits, to controlling millions? In research published today in Science Advances, we reveal a new technology that may offer a solution.

New Intel Horse Ridge Cryogenic Chip Offers High-Fidelity Two-Qubit Control: A Major Quantum Computing Breakthrough

By Griffin Davis 

Intel collaborates with QuTech, an advanced research center for quantum internet and quantum computing, to develop a new cryogenic control SoC called the Horse Ridge. The tech giant manufacturer claimed that this new chipset is a breakthrough in quantum computing. 

A “Mistral” supercomputer, installed in 2016, at the German Climate Computing Center (DKRZ, or Deutsches Klimarechenzentrum) on June 7, 2017 in Hamburg, Germany. The DKRZ provides HPC (high performance computing) and associated services for climate research institutes in Germany. Its high performance computer and storage systems have been specifically selected with respect to climate and Earth system modeling.

Right now, researchers and experts are finding it hard to understand quantum computations since they are complex mathematical equations. On the other hand, they also deal with quantum states, specifically superposition and entanglement. 

Because of these, traditional computers are currently unable to perform quantum computations because they don’t have the ability to harness the phenomenon of quantum mechanics. Since this is the case, experts are forced to create quantum supercomputers that are specifically developed to perform quantum computing. 
And now, Intel also developed a new SoC that could be used in these special desktops.

To help you have more idea about it, here are other details of Intel’s new Horse Ridge.

Will quantum computing deliver a big leap forward for battery cells?

By Michelle Lewis 

The Cologne-headquartered German Aerospace Center (DLR) and Cambridge Quantum Computing(CQC) in the UK is the latest pair to explore how quantum computing could help create better simulation models for battery development. The DLR is Germany’s research center for aeronautics and space.

As IBM defines it, “Quantum computing harnesses the phenomena of quantum mechanics to deliver a huge leap forward in computation to solve certain problems.”

DLR will use CQC’s quantum algorithms for solving partial differential equation systems to render a one-dimensional simulation of a lithium-ion battery cell.

This will lay the groundwork for exploring multi-scale simulations of complete battery cells with quantum computers, which are considered a viable alternative for rendering full 3D models. A multi-scale approach incorporates information from different system levels (e.g., atomistic, molecular, and macroscopic) to make a simulation more manageable and realistic. That, in turn, will potentially accelerate battery research and development for a variety of sustainable energy solutions.

DLR has previously used classical computer modeling to research a range of different battery types, including lithium-ion and other technologies.

The World’s Highest Performing Quantum Computer is Here

Our team of scientists, engineers and technicians, have built what is currently the highest performing quantum computer available.

With a quantum volume of 64, the Honeywell quantum computer is twice as powerful as the next alternative in the industry. That means we are closer to industries leveraging our solutions to solve computational problems that are impractical to solve with traditional computers.

“What makes our quantum computers so powerful is having the highest quality qubits, with the lowest error rates.  This is a combination of using identical, fully connected qubits and precision control,” said Tony Uttley, president of Honeywell Quantum Solutions.

By Daphne Leprince-Ringuet 

Quantum Motion says that its latest experiment paves the way for large-scale, practical quantum computers.

Forget about superconducting circuits, trapped ions, and other exotic-sounding manufacturing techniques typically associated with quantum computing: scientists have now shown that it is possible to create a qubit on a standard silicon chip, just like those found in any smartphone. 

UK-based start-up Quantum Motion has published the results of its latest experiments, which saw researchers cooling down CMOS silicon chips to a fraction of a degree above absolute zero (-273 degrees Celsius), enabling them to successfully isolate and measure the quantum state of a single electron for a whole nine seconds. 

The apparent simplicity of the method, which taps similar hardware to that found in handsets and laptops, is striking in comparison to the approaches adopted by larger players like IBM, Google or Honeywell, in their efforts to build a large-scale quantum computer.

Honeywell says quantum computers will outpace standard verification in ’18 to 24 months’

By Michael Vizard

Honeywell expects that as advances in quantum computing continue to accelerate over the next 18 to 24 months, the ability to replicate the results of a quantum computing application workload using a conventional computing platform simulation will come to an end.

The company’s System Model H1 has now quadrupled its performance capabilities to become the first commercial quantum computer to attain a 512 quantum volume. Ascertaining quantum volume requires running a complex set of statistical tests that are influenced by the number of qubits, error rates, connectivity of qubits, and cross-talk between qubits. That approach provides a more accurate assessment of a quantum computer’s processing capability that goes beyond simply counting the number of qubits that can be employed.

Honeywell today provides access to a set of simulation tools that make it possible to validate the results delivered on its quantum computers on a conventional machine. Those simulations give organizations more confidence in quantum computing platforms by allowing them to compare results. However, quantum computers are now approaching a level where at some point between 2022 and 2023 that will no longer be possible, Honeywell Quantum Solutions president Tony Uttley said.

The usefulness of most quantum computers is still significantly limited by the low number of qubits that hardware can support. But simple fiber optic cables – just like the ones used for broadband connections – could be the answer. 

A team of researchers from the National Institute of Standards and Technology (NIST) found that, with just a few tweaks, optical fiber can be used to communicate with the qubits sitting inside superconducting quantum computers, with the same level of accuracy as existing methods.

A Desktop Quantum Computer for Just $5,000

A cheap, portable quantum computer, aimed at schools and colleges will be launched later this year.

A Chinese start-up has unveiled plans to sell a desktop quantum computer costing less than $5,000. The new portable device is one of a range called SpinQ, aimed at schools and colleges. It is made by the Shenzhen SpinQ Technology, based in Shenzhen, China.

This is not the company’s first quantum computer. Last year, it started selling a desktop quantum computer for around $50,000. The desk in question would need to be sturdy given that the device weighs a hefty 55kg (121 lbs)—about the weight of a small adult. 

But the new machine will be simpler, more portable and cheaper. “This simplified version is expected to be released in the fourth quarter of 2021, such that it can be more affordable for most K-12 schools around the world,” say the team behind the device.
