Quantum Control

Edited by: Prof Matthew James, Prof Gerard Milburn, Prof John Gough

In conjunction with the Ninth International Workshop on Principles and Applications for Control of Quantum Systems, EPJ Quantum Technology would like to call for papers to be published in a Thematic Series on Quantum Control. Quantum Control has already led to significant improvements in technologies ranging from magnetic resonance to prototype quantum computers, from quantum high-precision sensors to quantum logic clocks, from single atom transistors to quantum noise suppression in gravitation wave detectors. The field is experiencing rapid development driven by the necessity of practical engineered quantum systems. This series will highlight how quantum control engineering is becoming an essential framework behind the implementation of Quantum Technology, and focus on its role in problems of design, stabilization, error-correction, noise reduction and filtering, and combating decoherence.

  1. The emergence of coherent quantum feedback control (CQFC) as a new paradigm for precise manipulation of dynamics of complex quantum systems has led to the development of efficient theoretical modeling and simu...
