Industrial giant Honeywell says it’s built the world’s best quantum computer – MIT Technology Review

Honeywell, a US company best known for its home thermostats, has announced that it has built the world’s most powerful quantum computer. While all eyes were on IBM and Google, which last year knocked heads over quantum supremacy, Honeywell has been working quietly on quantum tech that it plans to make available to clients via the internet in the next three months. 

How it works: Most quantum computers, including those being developed by IBM and Google, are built around superconducting qubits, which use supercooled circuits. Honeywell’s quantum computer uses a different technology, called ion traps, which hold ions—the computer’s qubits—in place with electromagnetic fields. Superconducting quantum chips are faster, but ion traps are more accurate and hold their quantum state for longer.
