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…
