Engineering energy-time entanglement from resonance fluorescence
Jian Wang, Xiu-Bin Liu, Ziqi Zeng +8
Resonance fluorescence from a coherently driven two-level emitter is a minimal quantum optical field that combines phase coherence with single-photon-level nonlinearity. Here we sh…
High-performance Sources of Multidimensionally Engineered Quantum Light Based on Monolithic Microcavity-metalens Interfaces
Jiantao Ma, Dong Liu, Shunfa Liu +15
The ultimate non-classic light sources for modern photonic quantum technology require on-demand generation of indistinguishable quantum light with high brightness and flexible engi…
Bell Inequality Violation with Vacuum-One-Photon Number Superposition States
Zi-Qi Zeng, Jian Wang, Xiu-Bin Liu +8
Entanglement is a central resource in quantum technologies, and the realization of photonic entanglement necessarily relies on interaction with matter. Resonance fluorescence (RF),…
Full Polarization Control of Photons with Evanescent Wave Coupling in the Ultra Subwavelength Gap of Photonic Molecules
Rui Zhu, Chenjiang Qian, Shan Xiao +16
Polarization of photons plays a key role in quantum optics and light-matter interactions, however, it is difficult to control in nanosystems since the eigenstate of a nanophotonic…
Two-photon interference between mutually-detuned resonance fluorescence signals scattered off a semiconductor quantum dot
Guoqi Huang, Jian Wang, Ziqi Zeng +9
The radiative linewidth of a two-level emitter (TLE) fundamentally limits the bandwidth available for quantum information processing. Despite its importance, no prior experiment ha…
Single-Photon Advantage in Quantum Cryptography Beyond QKD
Daniel A. Vajner, Koray Kaymazlar, Fenja Drauschke +8
Quantum key distribution (QKD) can be used to establish a secret key between trusted parties. Many practical use-cases in communication networks, however, involve parties who do no…
