Quantum Instruction Set Design for Performance
A quantum instruction set is where quantum hardware and software meet. We
develop new characterization and compilation techniques for non-Clifford gates
to accurately evaluate different quantum instruction set designs. We
specifically apply them to our fluxonium processor that supports mainstream
instruction by calibrating and characterizing its square root
. We measure a gate fidelity of up to with an average
of and realize Haar random two-qubit gates using
with an average fidelity of . This is an average error reduction of
for the former and a reduction for the latter compared to using
on the same processor. This shows designing the quantum
instruction set consisting of and single-qubit gates on such
platforms leads to a performance boost at almost no cost.Comment: 2 figures in main text and 21 figures in Supplementary Materials.
