QUANTUM ATMOSPHERE OF REISSNER-NORDSTRÖM BLACK HOLES

Ong, Yen Chin; Good, Michael R. R. (PHYSICAL REVIEW RESEARCH, 2020-08-27)

Hawking radiation originates from a “quantum atmosphere” around black holes, not necessarily from the vicinity of the horizon. We examine and discuss the properties of quantum atmospheres of asymptotically flat Reissne ...
Quantum compiling with diffusive sets of gates

Akulin, Vladimir M.; Mandilara, Aikaterini; Zhiyenbayev, Yertay (Nazarbayev University School of Sciences and Humanities, 2018-01-15)

Given a set of quantum gates and a target unitary operation, the most elementary task of quantum compiling is the identification of a sequence of the gates that approximates the target unitary to a determined precision ε. ...
