Simulating Heisenberg Interactions in the Ising Model with Strong Drive Fields
Anthony N. Ciavarella, Stephan Caspar, Hersh Singh +2
The time-evolution of an Ising model with large driving fields over discrete time intervals is shown to be reproduced by an effective XXZ-Heisenberg model at leading order in the i…
Quantifying the Impact of Precision Errors on Quantum Approximate Optimization Algorithms
Gregory Quiroz, Paraj Titum, Phillip Lotshaw +4
The quantum approximate optimization algorithm (QAOA) is a hybrid quantum-classical algorithm that seeks to achieve approximate solutions to optimization problems by iteratively al…
Hybrid quantum-classical approach for coupled-cluster Green's function theory
Trevor Keen, Bo Peng, Karol Kowalski +2
The three key elements of a quantum simulation are state preparation, time evolution, and measurement. While the complexity scaling of time evolution and measurements are well know…
Digital-Analog Quantum Simulations Using The Cross-Resonance Effect
Tasio Gonzalez-Raya, Rodrigo Asensio-Perea, Ana Martin +4
Digital-analog quantum computation aims to reduce the currently infeasible resource requirements needed for near-term quantum information processing by replacing sequences of one-…
Fully Arbitrary Control of Frequency-Bin Qubits
Hsuan-Hao Lu, Emma M. Simmerman, Pavel Lougovski +2
Accurate control of two-level systems is a longstanding problem in quantum mechanics. One such quantum system is the frequency-bin qubit: a single photon existing in superposition…
A practical and efficient approach for Bayesian quantum state estimation
Joseph M. Lukens, Kody J. H. Law, Ajay Jasra +1
Bayesian inference is a powerful paradigm for quantum state tomography, treating uncertainty in meaningful and informative ways. Yet the numerical challenges associated with sampli…
