Time-symmetric correlations for open quantum systems
Arthur J. Parzygnat, James Fullwood
Two-time expectation values of sequential measurements of dichotomic observables are known to be time symmetric for closed quantum systems. Namely, if a system evolves unitarily be…
General Communication Enhancement via the Quantum Switch
Zhen Wu, James Fullwood, Zhihao Ma +3
Recent studies have shown that quantum information may be effectively transmitted by a finite collection of completely depolarizing channels in a coherent superposition of differen…
General covariance for quantum states over time
James Fullwood
The theory of quantum states over time provides an approach to the dynamics of quantum information which is in direct analogy with spacetime and its relation to classical dynamics.…
On dynamical measures of quantum information
James Fullwood, Arthur J. Parzygnat
In this work, we use the theory of quantum states over time to define an entropy associated with quantum processes , where is a state and $\…
