Complete Quantum-State Tomography with a Local Random Field
Pengcheng Yang, Min Yu, Ralf Betzholz +2
Single-qubit measurements are typically insufficient for inferring arbitrary quantum states of a multi-qubit system. We show that if the system can be fully controlled by driving a…

Emerging unitary evolutions in dissipatively coupled systems
C. Arenz, A. Metelmann
Having a broad range of methods available for implementing unitary operations is crucial for quantum information tasks. We study a dissipative process commonly used to describe dis…

An upper bound on the time required to implement unitary operations
Juneseo Lee, Christian Arenz, Daniel Burgarth +1
We derive an upper bound for the time needed to implement a generic unitary transformation in a dimensional quantum system using control fields. We show that given the abil…
