Robust control of quantum systems by quantum systems

2021 · Physical Review A

Quantum systems can be controlled by other quantum systems in a reversible way, without any information leaking to the outside of the system-controller compound. Such coherent quantum control is deterministic, is less noisy than measurement-based …

Comment on the Quantum Supremacy Claim by Google

2021 · arXiv (Cornell University)

Quantum computation promises to execute certain computational tasks on time scales much faster than any known algorithm on an existing classical computer, for example calculating the prime factors of large integers. Recently a research team …
