Challenges for near term quantum computing
The perspective of using quantum computers to solve otherwise intractable computational problems is naturally exciting for scientists and is also starting to attract substantial industrial interest. The ultimate goal is to build large scale universal quantum computers, which support general quantum algorithms. However, due to daunting requirements regarding error control and qubit numbers this goal currently seems to be out of reach. In the intermediate time, special purpose machines are being developed that can solve at least some task substantially better than classical computers. Their applications range from mere demonstrators of "quantum supremacy" to hybrid quantum-classical algorithms for problems, e.g. from quantum chemistry and classical optimization.
