Hidden rotation symmetry of the Jordan-Wigner transformation and its application to measurement in quantum computation
Grant Davis, James K. Freericks
Using a global rotation by theta about the z-axis in the spin sector of the Jordan-Wigner transformation rotates Pauli matrices X and Y in the x-y-plane, while it adds a global com…
Classical reservoir approach for efficient molecular ground state preparation
Zekun He, Dominika Zgid, A. F. Kemper +1
Ground state preparation is a central application of quantum algorithms for electronic structure. We introduce the classical reservoir approach, a low cost variational ansatz tailo…
Probing Bound State Relaxation Dynamics in Systems Out-of-Equilibrium on Quantum Computers
Heba A. Labib, Goksu Can Toga, J. K. Freericks +1
Pump-probe spectroscopy is a powerful tool for probing response dynamics of quantum many-body systems in and out-of-equilibrium. Quantum computers have proved useful in simulating…
Efficient Fermi-Hubbard model ground-state preparation by coupling to a classical reservoir in the instantaneous-response limit
Zekun He, Lorenzo Del Re, A. F. Kemper +1
Preparing the ground state of the Fermi-Hubbard model is challenging, in part due to the exponentially large Hilbert space, which complicates efficiently finding a path from an ini…
