IonQ Releases A New 32-Qubit Trapped-Ion Quantum Computer system With Substantial Quantum Volume Promises

Final Could, I had a discussion with Peter Chapman, CEO of IonQ, a start out-up quantum computing company.  In advance of coming to IonQ, Chapman labored for Amazon, wherever he was liable for all the technical complexities of Amazon Key.  IonQ experienced accomplished a whole lot in the twelve months that Chapman experienced been at the helm, so I was searching ahead to talking to him.

My major surprise throughout that discussion was that IonQ was at the same time performing on its subsequent three generations of its trapped-ion quantum pcs – 5th, 6th, and 7th generations.

In a latest comply with-up with Chapman, together with Chris Monroe, IonQ’s Co-founder and Chief Scientist, we discussed IonQ’s release of its 5th generation quantum hardware.  Maintain in brain that the 6th and 7th generations are nonetheless in development. Chapman said that each technology would be scaled-down and a lot more potent than its predecessor when launched.  Although he failed to point out it, I would not be shocked if Chapman’s team hasn’t currently started work on IonQ’s 8th technology processor.

Capabilities of  IonQ’s new 5th era quantum pc

A qubit is the fundamental device of details in a quantum pc.  A classical computer bit can only be a a person or zero.  A qubit can also exist as a just one or zero, but when in a quantum point out, it can be a superposition of both of those values.  Ion states its newest quantum hardware has 32 ion qubits in its most current launch, almost tripling the 11 qubits in its preceding quantum computer system.  

Robert Niffenegger, a Ph.D. and a member of the Trapped Ion and Photonics team at MIT Lincoln Laboratory, mentioned he was not amazed at the big bounce in the variety of qubits. “Truthfully, I think a whole lot of men and women were just holding their breath right up until they [IonQ] declared. They have printed papers on strategies of cooling chains of 20 ions that have hinted that they had considerably extra than the 11 ions they set on the cloud – the question was just how a lot of?”

The new quantum pc also includes yet another new development. It enables random obtain on all-to-all gate functions. This enhancement will allow for a more successful program compilation of programs. In accordance to Chris Monroe, IonQ is also working on a long run functionality identical to Honeywell’s mid-circuit measurement and reuse.  

Our lack of ability to suitable qubit problems is a single of the reasons we are not able to establish quantum pcs bigger than a few hundred qubits.  Discovering a solution to error correction is critical to the long term of quantum computing. Which is why it has the attention of lots of scientists.  Some consider that as lots of as a person thousand qubits could possibly be necessary to accurate one particular qubit mistake.  These types of a necessity could final result in a quantum device the dimension of a football subject.  In its new processor, IonQ included a new error correction code that it suggests only uses 13 qubits. Monroe stated that when the code failed to engage in a major  part in this announcement, it will be helpful in later versions as qubits are scaled up. 

A quantum leap in quantum quantity

The most startling portion of IonQ’s new announcement was the claimed enormity of its new computer’s quantum quantity.   

Quantum quantity is a hardware-agnostic effectiveness measurement for gate-dependent quantum computers. IBM designed it in 2017.  QV considers this sort of items as the amount of qubits, connectivity of the qubits, gate fidelity, cross speak, circuit compiler effectiveness, and additional.  In other words and phrases, it usually takes far more than just adding qubits to increase the quantum quantity: the greater the QV, the additional strong the machine.

Quantum quantity generally requires jogging algorithms with quantum volume circuits. Right before IonQ’s announcement, Honeywell’s 7-qubit ion-trap quantum pc had the industry’s optimum printed quantum volume of 128. IBM had the following maximum QV of 64 with its 27-qubit superconducting quantum machine.   

It can be the recognized norm for quantum experts to publish scientific proof of new quantum hardware, program, and theories.  Honeywell documented its QV 128 with some facts on its web page.  And IBM published complex details about how it obtained QV 64 in a study paper.  In this situation, rather than jogging quantum quantity circuits with publishable results, IonQ resorted to calculating the quantum volume. Its calculated QV  was a staggering 4 million, and that only considered 22 of its offered 32 qubits. Which is pretty much 65,000 situations larger than the highest printed QV.

Jungsang Kim, co-founder and Main Engineering Officer, explained why IonQ decided to work out quantum quantity fairly than managing quantum quantity algorithms:  “We have a temp[orary] resolution for some of the optics that permitted us to have confidence in the gate fidelity that permitted us to estimate approximate QV. As we converse, we are putting in the final output optics and will be ready to get a closing number on the machine. The 4 million number essential only 22 qubits with 99.9% fidelity, and so we expect the remaining QV to only be restricted by the gate fidelity fairly than amount of qubits.”

Experienced all 32 qubits been made use of in IonQ’s calculation alternatively of just 22 qubits, the claimed, predicted quantum quantity would have exploded from 4 million to a quantum volume of around 4 billion.  That would be 31 million situations better than any quantum quantity ever published.

Niffenegger believes that the gate fidelity was not higher adequate to use all 32 qubits.  One more quantum theorist that I spoke to explained that two-qubit gates would have to have very little significantly less than 99.96% fidelity to accomplish a quantum quantity of that magnitude.

It will be settled, because in accordance to Chris Monroe IonQ will before long publish a investigate paper on the new processor.  

Other reactions 

As mentioned, IBM and Honeywell have every single beforehand revealed its respective quantum volume.  With that in intellect, I questioned every business for its reaction to the IonQ announcement. 

IBM provided this response: ” The Quantum sector bulletins this 7 days are appealing. Definitely, the ion entice-based mostly firms are expanding their aggressive depth in that phase of the current market. The growing use of Quantum Volume as a metric is also value noting. That reported, for further comment, we will wait until we see the associated investigation published and study more about the details of these information announcements. The IBM Quantum group is self-assured in our roadmap announcement previously this month. We have posted our final results and improvements for assessment and discussion with the scientific and analyst group. Our progress and improvements are shown and offered on the IBM Cloud now. To serve our fast growing foundation of about 260,000 registered users, we continue to be targeted on accelerating advancement in true utilization and continuing to push up circuit fidelity and all round circuit quantity.”

Honeywell’s CEO, Tony Uttley, also weighed in on the announcement. “IonQ’s announcement is very good for the development of quantum computing in normal. The simple fact that you can make large increases in qubits like this is what can make trapped-ion such an remarkable technological innovation.  It reveals the electrical power and foreseeable future likely of the platform.”


Analyst notes and conclusions:


  1. IonQ’s announcement substantially developments quantum computing in general.  Controlling 32 ions in a linear trap is no compact scientific feat. IonQ’s target is to double the amount qubits each year.  IonQ may well will need to include yet another quantum interconnected linear entice in the foreseeable future. 
  2. The launch of IonQ’s technology 5 machine delivers us a different stage closer to quantum benefit, a term that usually means quantum pcs can outperform classical devices in particular use scenarios.  Relying on the application, Peter Chapman thinks that 80 to 150 very large fidelity qubits and logic gates might obtain quantum edge.
  3. Not to diminish IonQ’s accomplishment, but simply because it is so spectacular, I’m obligated to connect with a foul. The basic scientific community normally makes bulletins before publishing a investigation paper.  Having said that, for many motives, which is not the norm in quantum exploration. A exploration paper is particularly critical if a benchmark assert exceeds its double-digit predecessors by a element of 65,000.  I do not think push release announcements on sizeable quantum achievements this sort of as IonQ’s with no proof can help to advance the industry. It is effortless to declare, but giving scientific proof is considerably more challenging. 
  4. It will be incredibly appealing when IonQ can make the new equipment obtainable to scientists. A lot of folks are curious what can be accomplished with 32 ions.  Anticipate to see early papers by economical institutions this sort of as JP Morgan Chase. 
  5. IonQ now has a presence on Amazon Braket and Microsoft Azure. I estimate that private betas applying the new components will start out within just a few months, and deployment on the cloud platforms will come about someday in mid- to late-2021
  6. Federal government funding and private expenditure monies are readily available for the reason that the general health of the quantum computing ecosystem is great. IBM a short while ago introduced a specific roadmap exhibiting a improvement route leading to a million qubit superconducting quantum laptop.  Google hinted at a identical roadmap. Moreover, Honeywell takes advantage of its innovative QCCD trapped-ion architecture with quite a few zones that have a lot of place for extra ions. And, photonics and silicon are commencing to make progress.
