Statistical Quantum Phase Estimation: Extensions and Practical Considerations
Amit Surana, Brandon Allen
We present several refinements and extensions of the statistical quantum phase estimation (SQPE) framework to address some of its key practical limitations, improving its applicabi…
Solving Constrained Optimization Problems Using Hybrid Qubit-Qumode Quantum Devices
Rishab Dutta, Brandon Allen, Chuzhi Xu +8
Variational Quantum Algorithms (VQAs) provide a promising framework for tackling complex optimization problems on near-term quantum hardware. Here, we demonstrate that hybrid qubit…
Asymmetry Control in a Parametric Oscillator for the Quantum Simulation of Chemical Activation
Alejandro Cros Carrillo de Albornoz, Rodrigo G. Cortiñas, Max Schäfer +8
Dissipative tunneling remains a cornerstone effect in quantum mechanics. In chemistry, it plays a crucial role in governing the rates of chemical reactions, often modeled as the mo…
A Roadmap for Simulating Chemical Dynamics on a Parametrically Driven Bosonic Quantum Device
Delmar G. A. Cabral, Pouya Khazaei, Brandon C. Allen +8
Chemical reactions are commonly described by the reactive flux transferring population from reactants to products across a double-well free energy barrier. Dynamics often involves…
Characterizing conical intersections of nucleobases on quantum computers
Yuchen Wang, Cameron Cianci, Irma Avdic +7
Hybrid quantum-classical computing algorithms offer significant potential for accelerating the calculation of the electronic structure of strongly correlated molecules. In this wor…
