Scattering Processes from Quantum Simulation Algorithms for Scalar Field Theories
Andrew Hardy, Priyanka Mukhopadhyay, M. Sohaib Alam +8
We provide practical simulation methods for scalar field theories on a quantum computer that yield improved asymptotics as well as concrete gate estimates for the simulation and ph…
Bacon-Shor Board Games
M. Sohaib Alam, Jun Zen, Thomas R. Scruby
We identify a period-4 measurement schedule for the checks of the Bacon-Shor code that fully covers spacetime with constant-weight detectors, and is numerically observed to provide…
Dynamical Logical Qubits in the Bacon-Shor Code
M. Sohaib Alam, Eleanor Rieffel
The Bacon-Shor code is a quantum error correcting subsystem code composed of weight 2 check operators that admits a single logical qubit, and has distance on a squ…
Highly-efficient quantum Fourier transformations for some nonabelian groups
Edison M. Murairi, M. Sohaib Alam, Henry Lamm +2
Quantum Fourier transformations are an essential component of many quantum algorithms, from prime factoring to quantum simulation. While the standard abelian QFT is well-studied, i…
Assessing and Advancing the Potential of Quantum Computing: A NASA Case Study
Eleanor G. Rieffel, Ata Akbari Asanjan, M. Sohaib Alam +20
Quantum computing is one of the most enticing computational paradigms with the potential to revolutionize diverse areas of future-generation computational systems. While quantum co…
