Riemannian gradient descent-based quantum algorithms for ground state preparation with guarantees
Mahum Pervez, Ariq Haqq, Nathan A. McMahon +1
We investigate Riemannian gradient flows for preparing ground states of a desired Hamiltonian on a quantum device. We show that the number of steps of the corresponding Riemannian…

In situ quantum verification of polarization-stabilized optical channels
Matthew L. Stevens, Noah I. Wasserbeck, Zachary Goisman +8
The active stabilization of polarization channels is a task of growing importance as quantum networks move to deployed demonstrations over existing fiber infrastructure. However, t…

Hamiltonian simulation in Zeno subspaces
Kasra Rajabzadeh Dizaji, Ariq Haqq, Alicia B. Magann +1
We investigate the quantum Zeno effect as a framework for designing and analyzing quantum algorithms for Hamiltonian simulation. We show that frequent projective measurements of an…
