Quantum photonics has a long history in the exploration of quantum information science, and now several university and industrial labs are positioned to build devices of sufficient complexity to perform valuable, though non-universal quantum computations. In this special symposium we hear from groups at the cutting edge of development of noisy intermediate-scale quantum (NISQ) processors, spanning topics from boson sampling, through variational algorithms, quantum simulation and machine learning, alongside techniques to cope with losses, fabrication errors and other realistic sources of noise.
