Classical symmetries and the Quantum Approximate Optimization Algorithm
Ruslan Shaydulin, Stuart Hadfield, Tad Hogg +1
We study the relationship between the Quantum Approximate Optimization Algorithm (QAOA) and the underlying symmetries of the objective function to be optimized. Our approach formal…
Cost Efficient Repository Management for Cloud-Based On-Demand Video Streaming
Mahmoud Darwich, Ege Beyazit, Mohsen Amini Salehiy +1
Video transcoding is the process of converting a video to the format supported by the viewer's device. Video transcoding requires huge storage and computational resources, thus, ma…
Quantum algorithms with local particle number conservation: noise effects and error correction
Michael Streif, Martin Leib, Filip Wudarski +2
Quantum circuits with local particle number conservation (LPNC) restrict the quantum computation to a subspace of the Hilbert space of the qubit register. In a noiseless or fault-t…
Ensuring Robustness in Training Set Based Global 21-cm Cosmology Analysis
Neil Bassett, David Rapetti, Keith Tauscher +2
We present a methodology for ensuring the robustness of our analysis pipeline in separating the global 21-cm hydrogen cosmology signal from large systematics based on singular valu…
Modelling the Galactic Foreground and Beam Chromaticity for Global 21-cm Cosmology
Joshua J. Hibbard, Keith Tauscher, David Rapetti +1
In order to characterize and model the beam-weighted foreground for global 21-cm signal experiments, we present a methodology for generating basis eigenvectors that combines analyt…
Character randomized benchmarking for non-multiplicity-free groups with applications to subspace, leakage, and matchgate randomized benchmarking
Jahan Claes, Eleanor Rieffel, Zhihui Wang
Randomized benchmarking (RB) is a powerful method for determining the error rate of experimental quantum gates. Traditional RB, however, is restricted to gatesets, such as the Clif…
