G06N 10/00

Quantum computing, i.e. information processing based on quantum-mechanical phenomena

Introduced: January 2019

Additional Content IPC

Quantum-mechanical phenomena covers quantum phenomena of superposition, coherence, decoherence, entanglement, nonlocality or teleportation.

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2022.
