- Authors: Arman A. Setser, Jason P. Kestner
- Abstract summary: We use a gradient-based optimization scheme to find single-qubit rotations to be interwoven between timesteps of a noisy logical two-qubit entangling gate.
We show how the sequence fidelity is affected by imperfections in the single-qubit operations, as well as by various relative strengths of the logical and leakage noise.

- Abstract: We use a gradient-based optimization scheme to find single-qubit rotations to
be interwoven between timesteps of a noisy logical two-qubit entangling gate in
order to suppress arbitrary logical and leakage errors in the two-qubit gate.
We show how the sequence fidelity is affected by imperfections in the
single-qubit operations, as well as by various relative strengths of the
logical and leakage noise. Our approach is completely general and
system-independent, allowing for application to any two-qubit system regardless
of the experimental implementation details.

Virtual distillation is an error-mitigation technique that reduces quantum-computation errors without assuming the noise type.
We show that for a given overall error rate, the average mitigation performance improves monotonically as the noisy peripheral is split(diluted) into more layers.
We propose an application of these findings in designing a quantum-computing cluster that houses realistic noisy intermediate-scale quantum circuits.
