Current state of quantum computing

Different technologies that can be used for quantum computation. Superconducting quantum computing is one of it

Scaling to bigger systems (i.e. more qubits, but with good other )

coherence times: Increase life time of a qubit

reliable operations (gate fidelities, readout, reset etc)

About this module

The NISQ (Noisy Intermediate-Scale Quantum) era refers to the current stage of development of quantum computers, where the available devices have a limited number of qubits (typically a few dozen to a few hundred), and suffer from high levels of noise and errors. Despite these limitations, NISQ devices are still capable of performing useful quantum computations and are being used to explore various quantum algorithms and applications. The term "Noisy Intermediate-Scale" highlights the fact that the devices are not yet powerful enough to perform fault-tolerant quantum computing, but are still useful for exploring the intermediate-scale problems that are beyond classical computers. The NISQ era is expected to last for several years until more advanced and reliable quantum computing technologies become available.
