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.…
Virtual quantum broadcasting
Arthur J. Parzygnat, James Fullwood, Francesco Buscemi +1
The quantum no-broadcasting theorem states that it is impossible to produce perfect copies of an arbitrary quantum state, even if the copies are allowed to be correlated. Here we s…
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 $\…
Quantum dynamics as a pseudo-density matrix
James Fullwood
While in relativity theory space evolves over time into a single entity known as spacetime, quantum theory lacks a standard notion of how to encapsulate the dynamical evolution of…
