Computing hardware

Who is turning quantum hardware into usable systems?

14 assessed in computing hardware · Edition 11 Sept 2026 · Method 1.0

A field guide to this sectorKnow what to compare

Match the machine to the experiment

Gate-based circuits, analog simulation and annealing offer different controls and solve different classes of problems. A larger physical-qubit count alone does not establish better useful performance.

Gate model
Programs a sequence of quantum gates.
Analog simulation
Programs an interacting physical system to model its dynamics.
Logical qubit
Quantum information encoded across physical qubits to control errors.
AWS: quantum computing models

Three questions worth asking

  1. Can you access the named system today, and under which plan?
  2. Does the result report errors, circuit depth and a credible classical baseline?
  3. Are the qubits physical or logical, and what operations were actually demonstrated?

Strength: An operating cloud service, detailed hardware controls and external experimental use give researchers concrete ways to work with annealing.

Limitation: An annealer does not execute arbitrary gate-model circuits. Reported hybrid business outcomes do not by themselves establish quantum speedup; the separate gate-model program is not validated by annealing results.
