Fictitious Copy Quantum Error Mitigation
Akib Karim, Harish J. Vallury, Muhammad Usman
Errors are arguably the most pressing challenge impeding practical applications of quantum computers, which has instigated vigorous research on the development of quantum error mit…
Quantum Spectral Authentication: Entity Authentication and Key Derivation from a Hidden Eigenstate of a Public Unitary Challenge
S. P. Kish, H. J. Vallury, J. Pieprzyk +2
We introduce Quantum Spectral Authentication (QSA), a symmetric-key entity-authentication and key-derivation protocol in which a remote endpoint proves it still holds a hidden plan…
Moments-based quantum computation of the electric dipole moment of molecular systems
Michael A. Jones, Harish J. Vallury, Manolo C. Per +2
With rapid progress being made in the development of platforms for quantum computation, there has been considerable interest in whether present-day and near-term devices can be use…
Arbitrary Ground State Observables from Quantum Computed Moments
Harish J. Vallury, Lloyd C. L. Hollenberg
The determination of ground state properties of quantum systems is a fundamental problem in physics and chemistry, and is considered a key application of quantum computers. A commo…
Precision ground-state energy calculation for the water molecule on a superconducting quantum processor
Michael A. Jones, Harish J. Vallury, Lloyd C. L. Hollenberg
The accurate computation of properties of large molecular systems is classically infeasible and is one of the applications in which it is hoped that quantum computers will demonstr…
Noise-robust ground state energy estimates from deep quantum circuits
Harish J. Vallury, Michael A. Jones, Gregory A. L. White +3
In the lead up to fault tolerance, the utility of quantum computing will be determined by how adequately the effects of noise can be circumvented in quantum algorithms. Hybrid quan…
Quantum computed moments correction to variational estimates
Harish J. Vallury, Michael A. Jones, Charles D. Hill +1
The variational principle of quantum mechanics is the backbone of hybrid quantum computing for a range of applications. However, as the problem size grows, quantum logic errors and…
