Industrial conglomerate Honeywell International Inc. said Tuesday that it plans to introduce an early-stage quantum computer for commercial experiments within about three months, with JPMorgan Chase & Co. as the first public user. A Honeywell executive said the machine is set to be the world's most powerful quantum computer by one measure, as it vies for a leading position in the nascent quantum-computing market against technology giants such as International Business Machines Corp., Alphabet Inc.'s Google and Microsoft...
Honeywell has launched its System Model H1, a quantum computer with a quantum volume of 128, as well as a cloud API that makes it available to enterprises. Quantum computers offer great promise for cryptography and optimization problems. ZDNet explores what quantum computers will and won't be able to do, and the challenges we still face. System Model H1 is also accessible through Microsoft Azure Quantum and via channel partners Zapata Computing and Cambridge Quantum Computing. Access to System Model H1 is available via subscription.
The H1 generation of computer, which uses trapped-ion technology, is strategically designed to be rapidly upgraded throughout its lifetime, said the company. Honeywell said the computer initially offers 10 fully connected qubits, a proven quantum volume of 128 and unique features such as mid-circuit measurement and qubit reuse. Quantum volume is a metric of the overall compute power of a quantum computer. According to a report in TechCrunch, the H1's quantum volume is higher than comparable efforts by IBM. But it is far behind what trapped-ion quantum computing startup IonQ claimed earlier this month it was able to achieve with 32 qubits.
The System Model H1, a ten-qubit quantum computer, has reached a quantum volume of 512. Honeywell's quantum scientists have quadrupled the capabilities of the company's quantum computer, with the device achieving record levels of performance less than a year after the first generation of the system was released. The System Model H1, a ten-qubit quantum computer, effectively reached a quantum volume of 512 – four times as much as was attained in the previous tweak of the system, which saw the H1 reach a quantum volume of 128. Released commercially last June (at the time as the System Model H0), the H1 makes use of trapped ions, unlike IBM and Google's devices, which are built with superconducting qubits. Honeywell's new record is eight times as much as was achieved with the System Model H0, which launched with a quantum volume of 64.
Honeywell's quantum computer is now commercially available after it was first announced in March. The company, best known in the US for making thermostats, says enterprise customers can access the machine either directly through one of its own interfaces or via Microsoft's Azure Quantum portal. As it did when it unveiled the device, Honeywell claims it's the world's most powerful quantum computer. Typically, when most companies talk about quantum computers, they usually mention qubits. Honeywell is instead using a metric called quantum volume to play up the capabilities of its machine.
