Control of open quantum systems: Case study of the central spin model
Christian Arenz, Giulia Gualdi, Daniel Burgarth
We study the controllability of a central spin guided by a classical field and interacting with a spin bath, showing that the central spin is fully controllable independently of th…
Optimal strategies for estimating the average fidelity of quantum gates
Daniel M. Reich, Giulia Gualdi, Christiane P. Koch
We show that the minimum experimental effort to characterize the proper functioning of a quantum device scales as 2^n for n qubits and requires classical computational resources ~…
Minimum number of input states required for quantum gate characterization
Daniel M. Reich, Giulia Gualdi, Christiane P. Koch
We derive an algebraic framework which identifies the minimal information required to assess how well a quantum device implements a desired quantum operation. Our approach is based…
