Abstract: We are well into the NISQ era of Noisy Intermediate Scale Quantum Computers. Four years on from Google's ‘quantum supremacy’ experiment, we have a deeper understanding of the nature of that experiment, the computing power of NISQ and novel techniques for benchmarking such computers and characterizing their error models.
At a foundational level, quantum supremacy provides a test of quantum mechanics in a new regime. I will also describe how concepts from cryptography have provided novel and counter-intuitive ways of probing quantum systems, and the prospects they hold for the next generation of quantum computers taking on the quantum supremacy challenge.
