quantum information
Superposition-encoded knowledge storage
Quantum information is data encoded in quantum systems—typically subatomic particles—where the fundamental unit is the qubit rather than the classical bit.
Unlike ordinary bits, which are either 0 or 1, qubits can exist in superposition, representing both states simultaneously until measured.
This property, along with entanglement between particles, enables quantum computers to perform certain calculations exponentially faster than classical machines.
The field encompasses quantum computing, quantum cryptography, and quantum communication.
