Quantum Trajectory Theory of Open Cavity-QED Systems with a Time Delayed Coherent Optical Feedback
… for example by increasing the stability and coherent lifetimes of these systems. Following the notable improvements using measurement-based feedback, time-delayed coherent optical feedback has been proposed as one such method of stabilizing and improving these systems. Furthermore, modelling …

Coherent control of electron spins in diamond for quantum information science and quantum sensing
… introduces and experimentally demonstrates coherent control techniques to exploit electron spins in diamond for applications in quantum information processing and quantum sensing. Specifically, optically-detected magnetic resonance measurements are performed on quantum states of single and …

Quantum control of spin systems in diamond
… frequency. The second approach exploits a coherent feedback protocol. We take advantage of a long-lived nuclear spin as an ancillary spin to protect the qubit of interest from decoherence. We show that the protocol protects the qubit as long as open-loop dynamical decoupling control schemes …

Efficient and coherent frequency conversions and nonlinear interference in optical parametric and atomic Raman processes
… from pump photons to idler photons can be a coherent process. Contrary to a common misconception, we show that the process can be free of quantum noise. With an interference experiment, we demonstrate that coherence is preserved in the conversion process. This technique could lead to a …
