Entanglement Breaking Structure of Cartan-Covariant Quantum Channels
Sean Prudhoe
Cartan-covariant quantum channels are introduced and studied using the Choi-Jamiołkowski isomorphism. The channels are Cartan-covariant as the covariance groups considered form sym…
Effective dynamics of qubit networks via phase-covariant quantum ensembles
Sean Prudhoe, Unnati Akhouri, Tommy Chin +1
We derive a new constructive procedure to rapidly generate ensembles of phase-covariant dynamical maps that may be associated to the individual spins of a closed quantum system. We…
Spontaneously interacting qubits from Gauss-Bonnet
Sean Prudhoe, Rishabh Kumar, Sarah Shandera
Building on previous constructions examining how a collection of small, locally interacting quantum systems might emerge via spontaneous symmetry breaking from a single-particle sy…
Classifying the non-time-local and entangling dynamics of an open qubit system
Sean Prudhoe, Sarah Shandera
We study families of dynamical maps generated from interactions with varying degrees of symmetry. For a family of time-independent Hamiltonians, we demonstrate the relationship bet…
