What is quantum entanglement?
Two objects, dependent on each other, with no measurable connection between them, not even light. The Bell tests, the Canary Islands experiment, and the 2022 Nobel Prize.

Building blocks
Short, visual explainers for the gates, states, and algorithms you keep running into. Each page has an interactive you can play with.
Gates
Gates
Hadamard gate
The gate that puts a qubit into superposition. The most-used gate in quantum computing.
Gates
Pauli-X gate
The quantum NOT. A 180° rotation about the x-axis, flips |0⟩ ↔ |1⟩.
Gates
Pauli-Y gate
A 180° rotation about the y-axis. Like X, but with an added 90° phase.
Gates
Pauli-Z gate
The phase flip. A 180° rotation about the z-axis, leaves |0⟩ alone, sends |1⟩ to −|1⟩.
Gates
T gate
A 45° phase rotation about the z-axis. The third gate in the H–T–CNOT universal set.
Gates
What is a quantum gate?
An operation that rotates a qubit on the Bloch sphere, the basic building block of every quantum algorithm.
Gates
CNOT gate
The two-qubit gate that creates entanglement. Flips the target qubit only when the control is |1⟩.
States
