Excitation Flow, Positivity, and Fisher Information for Open Subsystems of an -Qubit Network
Tommy Chin, Sarah Shandera
We derive closed-form propagators for any -qubit subsystem of a closed -qubit network with a single conserved excitation. A single transition amplitude simultaneously control…
Operator dynamics in k-Markov random circuits
Unnati Akhouri, Pei-Jun Huang, Elliott Rose +1
We demonstrate that -Markov sequences of unitary gates provide low-cost handles to manipulate the rate and structure of information spreading compared to traditional random, 0-M…
Open-systems tools for non-thermalizing closed quantum systems
Unnati Akhouri, Sarah Shandera, Jackson Henry
We design several examples of constrained, symmetric quantum circuit dynamics that generate non-equilibrium steady states. The qubit networks maintain local memory of the initial c…
Natural disorder distributions from measurement
Šárka Blahnik, Sarah Shandera
We consider scenarios where the dynamics of a quantum system are partially determined by prior local measurements of some interacting environmental degrees of freedom. The resultin…
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…
