Understand quantum — from qubits to companies.
No physics degree required. Each explainer takes a few minutes: how the technology works, the problem it solves, and the real companies building it — linked straight to their profiles and scores.
The 3-minute foundation everything else builds on.
The technologies & niches
Chip-based qubits cooled to near absolute zero. The current front-runner.
Individual atoms held by electric fields and steered with lasers. Highest fidelity.
Qubits made of light — room temperature, and built to manufacture.
Grids of atoms held by laser tweezers — flexible and fast-scaling.
A specialized machine for optimization — the longest commercial track record.
Protecting today's data from tomorrow's quantum computers.
The tools, compilers and algorithms that make the hardware useful.
Quantum's nearest-term payoff — measuring the world more precisely than ever.
