KEY POINTS

  • Physicists achieve a noise level 10 times lower than the previous record
  • Demonstration proves to take a major step closer to a full-scale silicon quantum processor 
  • Next step could be a 10-qubit prototype quantum integrated processor by 2023

The lowest noise level on record for a semiconductor quantum bit has been demonstrated by a team of quantum physicists, bringing the development of a commercially available silicon quantum computer one step forward to possibility. 

In a study published in Advanced Materials, the physicists said they were able to achieve a noise level 10 times lower than previously recorded for any semiconductor qubit. Specifically, they demonstrated a low-level charge noise of  S0 = 0.0088 ± 0.0004 μeV2 Hz−1. 

As a next step, the team is now looking forward to demonstrating the capability required to produce a reliable 10-qubit prototype quantum integrated processor by 2023. 

“Our team is now working towards

Last May, I had a discussion with Peter Chapman, CEO of IonQ, a start-up quantum computing company.  Before coming to IonQ, Chapman worked for Amazon, where he was responsible for all the technical complexities of Amazon Prime.  IonQ had accomplished a lot in the twelve months that Chapman had been at the helm, so I was looking forward to talking to him. 

My biggest surprise during that discussion was that IonQ was simultaneously working on its next three generations of its trapped-ion quantum computers – 5th, 6th, and 7th generations. 

In a recent follow-up with Chapman, including Chris Monroe, IonQ’s Co-founder and Chief Scientist, we discussed IonQ’s release of its 5th generation quantum hardware.  Keep in mind that the 6th and 7th generations are still in development. Chapman said that each generation would be smaller and more powerful than its predecessor when released.  Although he

Call it the quantum Garden of Eden. Fifty or so miles east of New York City, on the campus of Brookhaven National Laboratory, Eden Figueroa is one of the world’s pioneering gardeners planting the seeds of a quantum internet. Capable of sending enormous amounts of data over vast distances, it would work not just faster than the current internet but faster than the speed of light — instantaneously, in fact, like the teleportation of Mr. Spock and Captain Kirk in Star Trek.

Sitting in Brookhaven’s light-filled cafeteria, his shoulder-length black hair fighting to free itself from the clutches of a ponytail, Figueroa — a Mexico native who is an associate professor at Stony Brook University — tries to explain how it will work. He grabs

COLLEGE PARK, Md., Oct. 1, 2020 /PRNewswire/ — IonQ, the leader in quantum computing, today unveiled its next generation quantum computer system. The new hardware features 32 perfect qubits with low gate errors, giving it an expected quantum volume greater than 4,000,000.

The new system consists of perfect atomic clock qubits and random access all-to-all gate operations for efficient software compilation of applications. It will be first available via private beta, and then commercially available on Amazon Braket, where IonQ’s 11 qubit system is generally available for customers today, and Microsoft’s Azure Quantum. Pre-existing IonQ customers and partners, including 1QBit, Cambridge Quantum Computing, QC Ware, Zapata Computing and more are excited to experience the benefits of the new system, enabling them to drive towards the first wave of quantum applications.

The company’s trapped-ion quantum computers have a proven track record of outperforming all other available quantum hardware. With

LEESBURG, Va., Oct. 02, 2020 (GLOBE NEWSWIRE) — Quantum Computing Inc. (OTC:QUBT) (QCI), the technology leader in quantum-ready applications and tools, and only public pure-play in quantum computing, reports that the number of users on its performance-leading Mukai ™ quantum software development and execution platform has increased significantly since the introduction of a new trial program launched at the end of June.

“Dozens of new users have signed up for our Mukai trial, including major enterprises from the technology and finance sectors, U.S. Department of Energy national labs, large universities, and quantum computer (QC) providers,” stated John Dawson, QCI’s director of program management. Dawson, who oversees the trial program, previously led Cray Research’s worldwide IT organization and the software development team for its massively parallel and vector supercomputers.

“Most of our trial users are focused on solving real-world problems, exploring how Mukai can solve challenges in logistics, finance, supply chain

IonQ announces development of next generation quantum computer claiming it is the most powerful to date
Credit: IonQ

IonQ, a College Park, Maryland-based quantum computing hardware and software company has announced that it has launched its next generation quantum computer. As part of its announcement, the company is claiming that its new machine is the most powerful quantum computer built to date based on IBM’s quantum volume metric. The company has also announced that the new computer will be made available to customers soon.


Despite the headlines claiming that the age of quantum computers is upon us, they are still very much in their infancy. In most ways, conventional computers still outperform them by a wide margin. But the promise of future capabilities is fueling an ever-increasing competition between established companies like IBM, Microsoft and Google, and recent startups like IonQ.

Because the technology is still so new, quantum computer makers are working on different approaches to building them. IBM and Google, for example, use superconducting

Trapped-ion quantum computing startup IonQ today announced the launch of its latest quantum computer, which features what IonQ calls “32 perfect qubits with low gate errors.”

Using IBM’s preferred quantum benchmark, IonQ expects to hit a quantum volume of 4,000,000. That’s a massive increase over the double-digit quantum volume numbers that IBM itself recently announced and it’s a pretty extraordinary claim on IonQ’s side, as this would make its system the most powerful quantum computer yet.

The (well-funded) company has never used this metric before. Through a spokesperson, IonQ also noted that it doesn’t necessarily think quantum volume is the best metric, but since the rest of the industry is using it, it decided to release this number. The company argues that its ability to achieve 99.9% fidelity between qubits has allowed it to achieve this breakthrough.

“In a single generation of hardware, we went from 11 to 32 qubits,

On Thursday, the startup IonQ announced that the next generation of its ion-trap quantum computer was ready for use. The new machine marks a major jump for the company, going from 11 qubits up to 32. While this still trails the offerings of companies that are using superconducting qubits, the high fidelity of the trapped ions makes them far less prone to errors and far easier to link into complex configurations. So, by at least one measure of performance, this is the most powerful quantum computer yet made.

Perhaps more significantly, IonQ’s CEO told Ars that it expects to be able to double the number of qubits every eight months for the next few years, meaning its hardware should consistently outperform classical computers within two years.
