Therefore, determining whether a state is entangled or not is [...]

Training a quantum measurement device to discriminate unknown non-orthogonal quantum states

Marcelo Castellanos2024-03-27T13:57:24+01:00Tags: Multidisciplinary Sciences. |

Authors: Concha, D.; Pereira, L.; Zambrano, L.; Delgado, A. Journal: SCIENTIFIC REPORTS Publication date: 2023/05/08 DOI: 10.1038/s41598-023-34327-0 Abstract: Here, we study the problem of decoding information transmitted through unknown quantum states. We assume that Alice encodes an alphabet into a set of orthogonal quantum states, which are then transmitted to Bob. However, the quantum channel [...]
