Here, we report an experimental demonstration of three-qubit single-photon, linear, deterministic quantum gates that exploit photon polarization and the two-dimensional spatial-parity …

We describe the construction of controlled-NOT (CNOT), n√CNOT, controlled-PHASE, and Fredkin gates, and the preparation of one-photon, three-qubit Greenberger-Horne-Zeilinger …

In contrast, single-photon quantum logic (SPQL) aims to exploit the potentially large information-carrying capacity of a single photon to offer deterministic computation at the expense of an ...

2018年8月6日 · Wang et al. now show that they can entangle three degrees of freedom of six photons, providing control over an 18-qubit ensemble. The researchers employ the paths, the …

2017年9月29日 · Here, we report an experimental demonstration of three-qubit single-photon, linear, deterministic quantum gates that exploit photon polarization and the two-dimensional …

2021年1月29日 · The interaction between the field state and a system of three separable qubits is considered under Jaynes–Cummings model. Our study reveals that the three-qubit system …

2021年12月9日 · An evolution of a two-level system (qubit) interacting with a single-photon wave packet is analyzed. It is shown that a hierarchy of master equations gives rise to phase …

2024年1月25日 · Utilizing a tritter with variable parameter $T$ and induced by vacuum--one-photon superpositions $\left\vert 0\right\rangle +\alpha\left\vert 1\right\rangle $ with $\alpha …

2020年12月30日 · An evolution of a two-level system (qubit) interacting with a single-photon wave packet is analyzed. It is shown that a hierarchy of master equations gives rise to phase …
