Learning Clifford-structured quantum unitaries and Hamiltonians
Arkopal Dutt, Dale Jacobs, John Jeang +2
Learning algorithms for structured quantum unitaries and Hamiltonians have primarily considered classes of processes that are local or sparse in the Pauli basis. We turn our attent…

Quantum state isomorphism problems for groups
Alexandru Gheorghiu, Dale Jacobs, Saeed Mehraban +1
We study the computational complexity of quantum state isomorphism problems under group actions: given two quantum circuits that prepare pure or mixed states, decide whether the tw…

The Space Just Above One Clean Qubit
Dale Jacobs, Saeed Mehraban
Consider the model of computation where we start with two halves of a -qubit maximally entangled state. We get to apply a universal quantum computation on one half, measure bot…
