Mitigating Errors in DC Magnetometry via Zero-Noise Extrapolation
John S. Van Dyke, Zackary White, Gregory Quiroz
Zero-noise extrapolation (ZNE), a technique to estimate quantum circuit expectation values through noise scaling and extrapolation, is well-studied in the context of quantum comput…
Quantum tensor network algorithms for evaluation of spectral functions on quantum computers
Michael L. Wall, Aidan Reilly, John S. Van Dyke +2
We investigate quantum algorithms derived from tensor networks to simulate the static and dynamic properties of quantum many-body systems. Using a sequentially prepared quantum cir…
Time-crystalline behavior in central-spin models with Heisenberg interactions
Rafail Frantzeskakis, John Van Dyke, Leon Zaporski +5
Time-crystalline behavior has been predicted and observed in quantum central-spin systems with periodic driving and Ising interactions. Here, we theoretically show that it can also…
Scaling adaptive quantum simulation algorithms via operator pool tiling
John S. Van Dyke, Karunya Shirali, George S. Barron +3
Adaptive variational quantum simulation algorithms use information from the quantum computer to dynamically create optimal trial wavefunctions for a given problem Hamiltonian. A ke…
Preparing exact eigenstates of the open XXZ chain on a quantum computer
John S. Van Dyke, Edwin Barnes, Sophia E. Economou +1
The open spin-1/2 XXZ spin chain with diagonal boundary magnetic fields is the paradigmatic example of a quantum integrable model with open boundary conditions. We formulate a quan…
Preparing Bethe Ansatz Eigenstates on a Quantum Computer
John S. Van Dyke, George S. Barron, Nicholas J. Mayhall +2
Several quantum many-body models in one dimension possess exact solutions via the Bethe ansatz method, which has been highly successful for understanding their behavior. Neverthele…
