Quantum Conditions on Dynamics and Control in Open Systems
Lian-Ao Wu, Arjun Bharioke, Paul Brumer
Quantum conditions on the control of dynamics of a system coupled to an environment are obtained. Specifically, consider a system initially in a system subspace of dimensio…

Master Equation and Control of an Open Quantum System with Leakage
Lian-Ao Wu, Gershon Kurizki, Paul Brumer
Given a multilevel system coupled to a bath, we use a Feshbach P,Q partitioning technique to derive an exact trace-nonpreserving master equation for a subspace of…

Upper bounds for the secure key rate of decoy state quantum key distribution
Marcos Curty, Tobias Moroder, Xiongfeng Ma +2
The use of decoy states in quantum key distribution (QKD) has provided a method for substantially increasing the secret key rate and distance that can be covered by QKD protocols w…
