Pretty good quantum state transfer via transcendental edge weights

Addison Ballif, Mark Kempton, James B. Larsen +3

We prove that if we take a rooted product of a circulant graph with universal perfect state transfer with a path of fixed length whose end edge is weighted with a transcendental nu…

Constrained minimax approximation for quantum signal processing

Yulong Dong, James B. Larsen, Lin Lin +1

Quantum signal processing (QSP) provides a simple and efficient framework for implementing polynomial transformations using quantum circuits. Its classical design stage leads to a…

Equivariant Continuous Normalizing Flows with Offline Sampling for Fermionic Ground State Estimation

Sam Cochran, James B. Larsen, James Stokes +4

We introduce a framework for fermionic variational Monte Carlo in which a continuous normalizing flow refines a fixed antisymmetric base wavefunction. The flow is a permutation-equ…

Trajectory-independent speed limits for controlled open quantum systems

James B. Larsen, Tameem Albash, Alicia B. Magann +1

Existing quantum speed limits for controlled open quantum systems depend on the specified trajectory. For example, lower bounds on quantum annealing times in the presence of dissip…

Feedback-based quantum algorithms for ground state preparation

James B. Larsen, Matthew D. Grace, Andrew D. Baczewski +1

The ground state properties of quantum many-body systems are a subject of interest across chemistry, materials science, and physics. Thus, algorithms for finding ground states can…

Self-healing of Trotter error in digital adiabatic state preparation

Lucas K. Kovalsky, Fernando A. Calderon-Vargas, Matthew D. Grace +4

Adiabatic time evolution can be used to prepare a complicated quantum many-body state from one that is easier to synthesize and Trotterization can be used to implement such an evol…
