Representation matching for delegated quantum computing
Yuxiang Yang, Masahito Hayashi
Many quantum computational tasks have inherent symmetries, suggesting a path to enhancing their efficiency and performance. Exploiting this observation, we propose representation m…
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…
Optimal Universal Quantum Error Correction via Bounded Reference Frames
Yuxiang Yang, Yin Mo, Joseph M. Renes +2
Error correcting codes with a universal set of transversal gates are a desideratum for quantum computing. Such codes, however, are ruled out by the Eastin-Knill theorem. Moreover,…
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…
Entropic time-energy uncertainty relations: An algebraic approach
Christian Bertoni, Yuxiang Yang, Joseph M. Renes
We address entropic uncertainty relations between time and energy or, more precisely, between measurements of an observable and the displacement of the -generated evolut…
