Qubits

The quantum bit or qubit is the elementary unit that can carry quantum information.

Superposition

A qubit is a binary quantum state. The state can be well-determined (blue, orange) or undetermined (in superposition).

Entanglement

When two qubits are in a state where measuring one qubit can affect the result of measuring the other qubit,

Quantum operations

Quantum computation consists of applying a sequence of elementary quantum operations to qubits.

Circuits

Quantum circuits depict the sequence of operations applied to qubits in the course of a quantum computation.

Communication

Quantum communication takes place via standard optical fibers carrying photons.

Coming soon: Quantum interference

Interference is the key to understanding the difference between quantum computing and randomized computing.

Coming soon: Quantum nonlocality

What Einstein referred to as “spooky action at a distance” is a result of quantum entanglement.
