Best 1 qubit
qubit

A qubit is a fundamental unit of quantum information leveraging quantum mechanics. It differs from a classical bit by existing in multiple states simultaneously due to superposition. This allows for vastly increased computational possibilities. Qubits are relevant for researchers and developers expl...

2 density matrix

The density matrix is a mathematical tool used in quantum mechanics to represent the state of a quantum system. It accounts for both known and unknown components within that state, including mixed states resulting from interactions or entanglement. This formalism provides a way to describe open syst...

3 Bell state
Bell state

A Bell state describes a fundamental property in quantum mechanics involving the linked behavior of multiple subatomic particles, typically two qubits. These states exhibit correlations that cannot be explained by classical physics and are key to understanding phenomena like quantum entanglement. Th...

4 Bloch sphere

The Bloch sphere is a geometrical representation of a qubit's state, visualizing its superposition as a point on the surface of a unit sphere where axes represent classical bit values (0 and 1).
