Deep reinforcement learning for quantum gate control [PDF]
Europhysics letters, 2019 How to implement multi-qubit gates efficiently with high precision is essential for realizing universal fault-tolerant computing. For a physical system with some external controllable parameters, it is a great challenge to control the time dependence of ...

Poor man's topological quantum gate based on the Su-Schrieffer-Heeger model [PDF]
Physical review B, 2019 Topological properties of quantum systems could provide protection of information against environmental noise, and thereby drastically advance their potential in quantum information processing. Most proposals for topologically protected quantum gates are

Logical quantum processor based on reconfigurable atom arrays [PDF]
Nature, 2023 Suppressing errors is the central challenge for useful quantum computing1, requiring quantum error correction (QEC)2–6 for large-scale processing. However, the overhead in the realization of error-corrected ‘logical’ qubits, in which information is ...

High-Fidelity Photonic Three-Degree-of-Freedom Hyperparallel Controlled-Phase-Flip Gate
Frontiers in Physics, 2022 Encoding computing qubits in multiple degrees of freedom (DOFs) of a photonic system allows hyperparallel quantum computation to enlarge channel capacity with less quantum resource, and constructing high-fidelity hyperparallel quantum gates is always ...

Toward Quantum Gate-Model Heuristics for Real-World Planning Problems
IEEE Transactions on Quantum Engineering, 2020 Many challenging scheduling, planning, and resource allocation problems come with real-world input data and hard problem constraints, and reduce to optimizing a cost function over a combinatorially defined feasible set, such as colorings of a graph ...
