Proof-of-principle experimental demonstration of twin-field quantum key distribution over optical channels with asymmetric losses

npj Quantum Information, 2021
Twin-field (TF) quantum key distribution (QKD) is highly attractive because it can beat the fundamental limit of secret key rate for point-to-point QKD without quantum repeaters.

Low-Voltage Solution-Processed Zinc-Doped CuI Thin Film Transistors with NOR Logic and Artificial Synaptic Function

Nanomaterials, 2023
Low-voltage Zn-doped CuI thin film transistors (TFTs) gated by chitosan dielectric were fabricated at a low temperature. The Zn-doped CuI TFT exhibited a more superior on/off current ratio than CuI TFT due to the substitution or supplementation of copper

Simple security proofs for continuous variable quantum key distribution with intensity fluctuating sources

npj Quantum Information, 2021
Despite tremendous theoretical and experimental progress in continuous variable (CV) quantum key distribution (QKD), the security has not been rigorously established for most current continuous variable quantum key distribution systems that have ...

Transparent qubit manipulations with spin-orbit coupled two-electron nanowire quantum dot

Scientific Reports, 2021
We report on the first set of exact orthonormalized states to an ac driven one-dimensional (1D) two-electron nanowire quantum dot with the Rashba–Dresselhaus coexisted spin-orbit coupling (SOC) and the controlled magnetic field orientation and trapping ...

Efficient experimental quantum fingerprinting with channel multiplexing and simultaneous detection

Nature Communications, 2021
Quantum fingerprinting could allow an exponential quantum advantage in a cryptographic protocol, but current schemes are still difficult to scale. Here, the authors exploit wavelength division multiplexing to increase the channel capacity and reduce the ...

QNMs of slowly rotating Einstein–Bumblebee black hole

European Physical Journal C: Particles and Fields, 2023
We have studied the quasinormal modes (QNMs) of a slowly rotating black hole with Lorentz-violating parameter in Einstein–Bumblebee gravity. We analyse the slow rotation approximation of the rotating black hole in the Einstein–Bumblebee gravity, and ...

Effective metric of spinless binaries with radiation-reaction effect up to fourth post-Minkowskian order in effective-one-body theory

European Physical Journal C: Particles and Fields, 2023
By means of the scattering angles, we obtain an effective metric of spinless binaries with radiation-reaction effects up to fourth post-Minkowskian order, which is the foundation of the effective-one-body theory.

Positive and Negative Photoconductivity Conversion Induced by H2O Molecule Adsorption in WO3 Nanowire

Nanoscale Research Letters, 2019
Negative photoconductivity effect has been observed in the Au/WO3 nanowire/Au devices in a high humidity environment, which might be attributed to the accumulation of H+ ions on the surface of WO3 nanowire.
