Efficient re-sampling in quasi-probability decompositions

This work introduces a reweighting strategy for QPDs for circuits with the same variational structure across parameter settings, reusing samples and thereby reducing the sampling overhead, and finds that this method outperforms other standard estimation techniques.

Analytic gradients for low-rank quantum optimal control

We introduce low-rank optimal control (LROC), a method for designing control pulses in open quantum systems whose full density-matrix simulation is prohibitively expensive. The method exploits a feature of quantum computing itself: because protocols are designed to preserve purity, the density matrix is dominated by a...
