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. The term tries to capture the “quality” of qubits. The larger the quantum volume value, the more complex problems the computer can solve. Honeywell says its computer features a quantum volume of 64. For context, IBM recently said its latest quantum computer had a quantum volume of 32.
