Quantinuum

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.

Highest Quantum Volume on Earth

Quantinuum's H2 holds the world record — 2²¹ quantum volume, orders of magnitude above rivals.

The Story

Timeline.

2018

Honeywell begins commercial quantum program, leveraging decades of ion-trap physics.

2020

Honeywell announces the H1, the first machine with quantum volume 64.

2021

Merges with Cambridge Quantum to form Quantinuum — hardware plus software under one roof.

2023

Demonstrates the first logical qubit outperforming its physical counterparts.

2024

H2 machine passes quantum volume 2^21 and demonstrates 12 logical qubits with Microsoft.

2025

Files confidentially for IPO at reported multi-billion valuation.

What makes them different

Key Facts

  • Holds the highest quantum volume of any quantum computer.
  • QCCD architecture physically moves ions between zones — a chip you can 'wire' in real time.
  • Powers Microsoft Azure's premium quantum backend.
  • Ships InQuanto for chemistry and TKET for circuit compilation.

Real-world pilots

Quantum Uses Today

  • Cybersecurity — Quantum Origin generates verifiably random encryption keys.
  • Chemistry pilots with BMW, JSR and Airbus.
  • Machine learning on quantum-generated feature spaces.

If they succeed

Potential Applications

  • Fault-tolerant logical qubits at the scale needed for cryptanalysis.
  • Quantum-enhanced AI training loops.
  • Simulation of nitrogenase and other 'grand challenge' molecules.
