Compression for Qubit Clocks
Yuxiang Yang, Giulio Chiribella, Masahito Hayashi
Two-Ievel (qubit) clock systems are often used to perform precise measurement of time. In this work, we propose a compression protocol for identically prepared states of qubit…
Third-harmonic generation of spatially structured light in a quasi-periodically poled crystal
Yan-Chao Lou, Zi-Mo Cheng, Yu-Xiang Yang +4
Nonlinear optical processes of spatially structured light, including optical vortex and vector optical fields, have stimulated a lot of interesting physical effects and found a var…
Quantum metrology for non-Markovian processes
Anian Altherr, Yuxiang Yang
Quantum metrology is a rapidly developing branch of quantum technologies. While various theories have been established on quantum metrology for Markovian processes, i.e., quantum c…
Optimal universal programming of unitary gates
Yuxiang Yang, Renato Renner, Giulio Chiribella
A universal quantum processor is a device that takes as input a (quantum) program, containing an encoding of an arbitrary unitary gate, and a (quantum) data register, on which the…
Ultimate limit on time signal generation
Yuxiang Yang, Renato Renner
The generation of time signals is a fundamental task in science. Here we study the relation between the quality of a time signal and the physics of the system that generates it. Ac…
Communication Cost of Quantum Processes
Yuxiang Yang, Giulio Chiribella, Masahito Hayashi
A common scenario in distributed computing involves a client who asks a server to perform a computation on a remote computer. An important problem is to determine the minimum amoun…
