Quantum Computing, Nisq, Qubit Fidelity, Quantum Error Correction, Near Perfect Qubits.
(\d+(\.d+)?)? means that a decimal number may optionally be written after NP, specifying some integer number of nines of qubit fidelity and optionally some fraction of a single nine. The intent of the fraction is to capture a half a nine or thirds or quarters of nines, such as 3.5, 4.25, 4.75,
