Quantum 6, 782 (2022). https://doi.org/10.22331/q-2022-08-23-782 Parameterized quantum circuits (PQCs) are a central component of many variational quantum algorithms, yet there is a lack of understanding of how their parameterization impacts algorithm performance. We initiate this […]
Quantum 6, 781 (2022). https://doi.org/10.22331/q-2022-08-22-781 We present a new hybrid, local search algorithm for quantum approximate optimization of constrained combinatorial optimization problems. We focus on the Maximum Independent Set problem and demonstrate the ability of […]
Quantum 6, 780 (2022). https://doi.org/10.22331/q-2022-08-17-780 Conventional methods of quantum simulation involve trade-offs that limit their applicability to specific contexts where their use is optimal. In particular, the interaction picture simulation has been found to provide […]
Quantum 6, 779 (2022). https://doi.org/10.22331/q-2022-08-17-779 Recently, table-top experiments involving massive quantum systems have been proposed to test the interface of quantum theory and gravity. In particular, the crucial point of the debate is whether it […]
Quantum 6, 778 (2022). https://doi.org/10.22331/q-2022-08-17-778 Mutually unbiased bases correspond to highly useful pairs of measurements in quantum information theory. In the smallest composite dimension, six, it is known that between three and seven mutually unbiased […]

Quantum 6, 776 (2022). https://doi.org/10.22331/q-2022-08-16-776 The classical shadows protocol, recently introduced by Huang, Kueng, and Preskill [Nat. Phys. 16, 1050 (2020)], is a quantum-classical protocol to estimate properties of an unknown quantum state. Unlike full […]
Quantum 6, 775 (2022). https://doi.org/10.22331/q-2022-08-11-775 The task of determining whether a given quantum channel has positive capacity to transmit quantum information is a fundamental open problem in quantum information theory. In general, the coherent information […]
Quantum 6, 774 (2022). https://doi.org/10.22331/q-2022-08-11-774 We introduce Mitiq, a Python package for error mitigation on noisy quantum computers. Error mitigation techniques can reduce the impact of noise on near-term quantum computers with minimal overhead in […]
Quantum 6, 773 (2022). https://doi.org/10.22331/q-2022-08-04-773 Quantum state preparation is an important ingredient for other higher-level quantum algorithms, such as Hamiltonian simulation, or for loading distributions into a quantum device to be used e.g. in the […]
