TL;DR: This work improves the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume (QV), with a combination of dynamical decoupling, compiler optimizations, shorter two-qubit gates, and excited state promoted readout.
Journal ArticleDOI
RBFOpt: an open-source library for black-box optimization with costly function evaluations
Alberto Costa,Giacomo Nannicini +1 more
TL;DR: The two main methodological contributions of this paper are an approach to exploit a noisy but less expensive oracle to accelerate convergence to the optimum of the exact oracle, and the introduction of an automatic model selection phase during the optimization process.

Breaking the 49-Qubit Barrier in the Simulation of Quantum Circuits
Edwin P. D. Pednault,John A. Gunnels,Giacomo Nannicini,Lior Horesh,Thomas Magerlein,Edgar Solomonik,Robert L. Wisnieff +6 more
TL;DR: In this paper, the authors presented a new approach for computing the output amplitudes of a universal random circuit with depth 27 in a 2D lattice of $7 \times 7$ qubits.
Journal ArticleDOI
Improving Variational Quantum Optimization using CVaR
Panagiotis Kl. Barkoutsos,Giacomo Nannicini,Anton Robert,Anton Robert,Ivano Tavernelli,Stefan Woerner +5 more
TL;DR: This paper empirically shows that the Conditional Value-at-Risk as an aggregation function leads to faster convergence to better solutions for all combinatorial optimization problems tested in this study.
