How to Build a Quantum Supercomputer: Scaling from Hundreds to Millions of Qubits
Masoud Mohseni, Artur Scherer, K. Grace Johnson +48
In the span of four decades, quantum computation has evolved from an intellectual curiosity to a potentially realizable technology. Today, small-scale demonstrations have become po…
Surrogate Constructed Scalable Circuits ADAPT-VQE in the Schwinger model
Erik Gustafson, Kyle Sherbert, Adrien Florio +8
Inspired by recent advancements of simulating periodic systems on quantum computers, we develop a new approach, (SC)-ADAPT-VQE, to further advance the simulation of these syste…
Benchmarking the performance of a high-Q cavity qudit using random unitaries
Nicholas Bornman, Tanay Roy, Joshua A. Job +4
High-coherence cavity resonators are excellent resources for encoding quantum information in higher-dimensional Hilbert spaces, moving beyond traditional qubit-based platforms. A n…
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…
Imposing Constraints on Driver Hamiltonians and Mixing Operators: From Theory to Practical Implementation
Hannes Leipold, Federico M. Spedalieri, Stuart Hadfield +1
Driver Hamiltonians and Mixing Operators that satisfy constraints is an important part of ansatz construction for many quantum algorithms. In this manuscript, we give general algeb…
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…
