Noisy intermediate-scale quantum era

The term "Noisy Intermediate-Scale Quantum (NISQ) era" refers to the current stage of quantum computing technology, characterized by the existence of quantum processors that possess a limited number of qubits (typically ranging from tens to a few hundred) and are susceptible to errors due to decoherence and noise. NISQ devices are not yet capable of performing error-corrected quantum computations, which makes them "noisy" and intermediary between classical and full-scale quantum computing.
