quantum gate directory
Quantum gates are the fundamental building block of quantum computation. This website aims to provide information regarding quantum gates seen in literature, and in practice in building quantum computers.
Periodic Table of Gates
Groups
Subgroups of the unitary group $\mathsf{U}(n)$ that are of particular importance. Every gate lives inside the unitary group; click a region to read about that subgroup.
The small grey labels mark one example gate per intersection.
SDK Support
Wondering which framework implements a gate natively? The SDK support matrix shows every gate against Qiskit, PennyLane, Cirq, Q#, PyQuil, Braket, BQSKit, Qibo, pytket, Stim, and OpenQASM, with links into each SDK's documentation.
