The state of quantum computing in 2026

Classical computers store information as bits — 0 or 1. Quantum computers use qubits, which can exist in a superposition of both states at once and can be entangled with one another so their states become correlated regardless of distance. That difference doesn't make quantum computers faster at everything — it makes them differently suited to a narrow but important set of problem structures, described below.

The state of the field, 2026

Quantum computing remains a small, fast-growing, pre-commercial industry. The gap between hardware headlines and deployed business value is still wide — but both the funding and the technical benchmarks are moving quickly.
