The table maker's quantum search

Benjamin C. A. Morrison, Stefanos Kourtis

We show that quantum search can be used to compute the hardness to round an elementary function, that is, to determine the minimum working precision required to compute the values…

JaqalPaw: A Guide to Defining Pulses and Waveforms for Jaqal

Daniel Lobser, Joshua Goldberg, Andrew J. Landahl +8

One of the many challenges of developing an open user testbed such as QSCOUT is providing an interface that maintains simplicity without compromising expressibility or control. Thi…

Logical fermions for fault-tolerant quantum simulation

Andrew J. Landahl, Benjamin C. A. Morrison

We show how to absorb fermionic quantum simulation's expensive fermion-to-qubit mapping overhead into the overhead already incurred by surface-code-based fault-tolerant quantum com…

Just another quantum assembly language (Jaqal)

Benjamin C. A. Morrison, Andrew J. Landahl, Daniel S. Lobser +4

The Quantum Scientific Computing Open User Testbed (QSCOUT) is a trapped-ion quantum computer testbed realized at Sandia National Laboratories on behalf of the Department of Energy…

Evaluating energy differences on a quantum computer with robust phase estimation

A. E. Russo, K. M. Rudinger, B. C. A. Morrison +1

We adapt the robust phase estimation algorithm to the evaluation of energy differences between two eigenstates using a quantum computer. This approach does not require controlled u…

Oracle Separations Between Quantum and Non-interactive Zero-Knowledge Classes

Benjamin Morrison, Adam Groce

We study the relationship between problems solvable by quantum algorithms in polynomial time and those for which zero-knowledge proofs exist. In prior work, Aaronson [arxiv:quant-p…
