Quantinuum
“The trapped-ion world-record holder.”
Honeywell-born trapped-ion leader holding the world record for quantum volume and demonstrating logical qubits at scale.
Quantinuum's H2 holds the world record — 2²¹ quantum volume, orders of magnitude above rivals.
The Story
Honeywell begins commercial quantum program, leveraging decades of ion-trap physics.
Honeywell announces the H1, the first machine with quantum volume 64.
Merges with Cambridge Quantum to form Quantinuum — hardware plus software under one roof.
Demonstrates the first logical qubit outperforming its physical counterparts.
H2 machine passes quantum volume 2^21 and demonstrates 12 logical qubits with Microsoft.
Files confidentially for IPO at reported multi-billion valuation.
