Inverse-coefficient black-box quantum state preparation

2022 · New Journal of Physics

Abstract Black-box quantum state preparation is a fundamental building block for many higher-level quantum algorithms. The basic task of black-box state preparation is to transduce the data encoded as computational basis of quantum state into …

Manipulating the quantum steering direction with sequential unsharp measurements

2022 · Physical Review A

Quantum steering exhibits an inherent asymmetric property that differs from both quantum entanglement and Bell nonlocality, which leads to no-way, one-way, and two-way steering. Flexibly manipulating the direction of quantum steering without reducing the quantum …
