# Quantum Computing - from NISQ to PISQ

@article{Bertels2021QuantumC, title={Quantum Computing - from NISQ to PISQ}, author={Koen Bertels and Aritra Sarkar and Imran Ashraf}, journal={IEEE Micro}, year={2021}, volume={41}, pages={24-32} }

Given the impeding timeline of developing good quality quantum processing units, it is the moment to rethink the approach to advance quantum computing research. Rather than waiting for quantum hardware technologies to mature, we need to start assessing in tandem the impact of the occurrence of quantum computing in various scientific fields.However, to this purpose, we need to use a complementary but quite different approach than proposed by the NISQ vision, which is heavily focused on and…
