This article from NIST provides a comprehensive glossary of terms related to quantum networks and quantum communication technologies. Key terms include:
– Cluster states: A type of entangled qubit state used in quantum networks
– Entanglement: A quantum phenomenon where particles become interconnected, with measurements on one affecting the others
– Fidelity: A measure of how similar two quantum states are
– Fock states: Quantum states describing a definite number of particles
– Nitrogen-vacancy centers: Quantum defects in diamond used for quantum information processing
– Nonclassical light: Light that cannot be described by classical physics
– Photon number statistics: The probability distribution of finding a certain number of photons
– Quantum communications: Secure information exchange using quantum principles
– Quantum dots: Semiconductor particles with discrete electronic states
– Qubits: The quantum equivalent of classical bits
– Quantum key distribution (QKD): Protocols for secure key exchange using quantum principles
– Quantum repeaters: Devices that extend quantum communication over long distances
– Quantum transducers: Devices that convert quantum states between different physical systems
– Rydberg atoms: Atoms with highly excited electrons
– Single photons: Individual particles of light
– Single-photon detectors: Devices that can detect individual photons
– Single-photon sources: Devices that emit individual photons
– Superposition: A quantum state that exists in multiple states simultaneously
The glossary provides a valuable resource for understanding the terminology used in quantum network research and development.
