Quantum optimization using variational algorithms on near-term quantum devices
N. Moll, P. Barkoutsos, L. Bishop +15 more·Oct 3, 2017
Universal fault-tolerant quantum computers will require error-free execution of long sequences of quantum gate operations, which is expected to involve millions of physical qubits. Before the full power of such machines will be available, near-term q...
