MonteQ: A Monte Carlo Tree Search Based Quantum Circuit Synthesis Framework
Mulundano Machiya, Matt Menickelly, Paul Hovland +1
Hamiltonian simulation is one of the most promising paths toward quantum advantage. Most prior approaches to Hamiltonian simulation circuit synthesis focus on local rewrite rules a…
Variational quantum state preparation within an entangle-rotate circuit framework for quantum-enhanced metrology in noisy systems
Juan C. Zuñiga Castro, Jeffrey Larson, Matt Menickelly +4
We investigate the generation of quantum states for precision metrology in noisy two-level systems. These states are obtained by optimizing a variational quantum circuit to maximiz…
Challenges with Differentiable Quantum Dynamics
Sri Hari Krishna Narayanan, Michael Perlin, Robert Lewis-Swan +4
Differentiable quantum dynamics require automatic differentiation of a complex-valued initial value problem, which numerically integrates a system of ordinary differential equation…
TROPHY: Trust Region Optimization Using a Precision Hierarchy
Richard J Clancy, Matt Menickelly, Jan Hückelheim +3
We present an algorithm to perform trust-region-based optimization for nonlinear unconstrained problems. The method selectively uses function and gradient evaluations at different…
