High-fidelity Rydberg controlled-Z gates with optimal pulses

Autor: Chang, T. H., Wang, T. N., Jen, H. H., Chen, Y. -C.

Publikováno v: New J. Phys. 25, 123007 (2023)

High-fidelity control-$Z$ ($C_Z$) gates are essential and mandatory to build a large-scale quantum computer. In neutral atoms, the strong dipole-dipole interactions between their Rydberg states make them one of the pioneering platforms to implement $

Evidence for a flavor asymmetry between the $\bar u$ and $\bar d$ quark distributions in the proton has been found in deep-inelastic scattering and Drell-Yan experiments. The pronounced dependence of this flavor asymmetry on $x$ (fraction of nucleon

Report

Almost indistinguishable single photons via multiplexing cascaded biphotons with cavity modulation and phase compensation

Autor: Wong, Y. -E., Chang, T. H., Jen, H. H.

Publikováno v: Phys. Rev. A 105, 063706 (2022)

The cascade-emitted biphotons generated from the alkali metal atomic ensembles are an excellent entanglement resource which enables long-distance quantum communication. The communication of quantum information between distant locations can be realize

Report

Spectral shaping of the biphoton state from multiplexed thermal atomic ensembles

Autor: Chang, T. H., Lin, G. -D., Jen, H. H.

Publikováno v: J. Phys. B: At. Mol. Opt. Phys. 53, 085403 (2020)

We theoretically investigate the spectral property of a biphoton state from multiplexed thermal atomic ensembles. This biphoton state originates from the cascade emissions, which can be generated by two weak pump fields under four-wave mixing conditi

Report

Spectrally entangled biphoton state of cascade emissions from a Doppler-broadened atomic ensemble

Autor: Chang, T. H., Lin, G. -D., Jen, H. H.

Publikováno v: J. Phys. B: At. Mol. Opt. Phys. 52, 135501 (2019)

We theoretically investigate the spectral property of biphoton state from the cascade emissions from a Doppler-broadened atomic ensemble. This biphoton state is spontaneously created in the four-wave-mixing process. The upper transition of the emissi
