Quantum computing service provider Quantinuum ups its hardware to 20 qubits

Quantinum Ltd.a startup that claims to be the world’s largest independent quantum computing company, has announced a major hardware upgrade which expands its System Model H1-1 platform to 20 fully connected qubits, making it possible to process quantum operations in parallel.

The company said the computational capabilities of the H1-1 quantum machine have been “significantly bolstered” by the update, and that’s very good news for developers and researchers using its platform.

Quantinuum is one of the world’s first providers of commercial quantum computing services. He developed his trapped-ion-based quantum computer, which is based on charged particles suspended in a vacuumin conjunction with Honeywell International Inc. Their machines are available for use by researchers through services such as quantum origina cybersecurity offer, and InQuanto, which is a recently released quantum computational chemistry software. By purchasing InQuanto software licenses, chemical researchers gain access to Quantinuum’s H1-1 machine. Additionally, Quantinuum’s H1-1 and H1-2 machines, as well as H1-1 emulators, can be accessed through Microsoft Corp’s Azure Quantum service.

The upgrades announced today increase the number of fully connected qubits in the H1-1 quantum computer from 12 to 20, significantly increasing its power. Qubits are what are at the heart of quantum computers and give them their unique abilities. While traditional computers rely on “bits” that represent information as “0” or “1”, qubits can represent data as “0”, “1”, or both at the same time, a capability that exponentially increases their computational power. . .

By adding more qubits, Quantinuum said it has managed to preserve its low two-qubit gate errors, with typical performance fidelities of 99.7%, along with other critical features. Meanwhile, the number of gate zones supported by H1-1 has been increased from three to five, allowing it to complete more quantum calculations simultaneously without affecting performance.

Quantinuum president and COO Tony Uttley said the updates will allow developers to run more complex calculations than before, without sacrificing performance. “This upgrade is yet another example of our unique business model of continually upgrading our systems, even after they are in business use, to deliver the best performance for our users,” he added.

The Quantinuum H1-1 system has been extensively tested by the company’s experts and also by JP Morgan Chase in a private preview. Marco Pistoia, Ph.D., a distinguished engineer and director of quantum computing at the bank, said he was very impressed with what he saw.

“In our experiments, we use the 20 qubits of the H1-1 computer in a quantum natural language processing algorithm for extractive text summarization,” Pistoia said. “The results were nearly identical to baseline values ​​calculated with a silent simulator, validating the high fidelity of the computer, as shown in our recent arXiv preprint. Thanks to this, the Quantinuum computer continues to be a fundamental resource for our research in Quantum Computing”.

Quantinuum’s next step will be to apply the same updates to its second machine, H1-2.

Quantinuum’s claim to be the world’s largest independent quantum computing firm comes after several of its rivals in the space, including D-Wave Systems Inc., Computing Rigetti Inc. Y IonQ Inc. everything was recently made public.
