Experimental quantum teleportation
TLDR
It is shown that during teleportation, one of a pair of entangled photons are subjected to a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon. Expand
Satellite-based entanglement distribution over 1200 kilometers
TLDR
Satellite-based distribution of entangled photon pairs to two locations separated by 1203 kilometers on Earth, through two satellite-to-ground downlinks is demonstrated, with a survival of two-photon entanglement and a violation of Bell inequality. Expand
Satellite-to-ground quantum key distribution
TLDR
This work reports the development and launch of a low-Earth-orbit satellite for implementing decoy-state QKD—a form ofQKD that uses weak coherent pulses at high channel loss and is secure because photon-number-splitting eavesdropping can be detected. Expand
Polarization entanglement purification using spatial entanglement.
TLDR
Surprisingly, spatial entanglement as an additional resource also leads to a substantial improvement in entangling output compared to the previous scheme, which relied on ideal single-pair sources. Expand
Measurement-Device-Independent Quantum Key Distribution Over a 404 km Optical Fiber.
TLDR
This record-breaking implementation of the MDIQKD method provides a new distance record and achieves a distance that the traditional Bennett-Brassard 1984 QKD would not be able to achieve with the same detection devices even with ideal single-photon sources. Expand
Experimental long-distance decoy-state quantum key distribution based on polarization encoding.
TLDR
The decoy-state quantum key distribution (QKD) with one-way quantum communication in polarization space over 102 km is demonstrated and can really offer the unconditionally secure final keys. Expand
Softening of roton and phonon modes in a Bose-Einstein condensate with spin-orbit coupling.
TLDR
Using Bragg spectroscopy, a SO-coupled Bose-Einstein condensate of ^{87}Rb atoms is studied and it is shown that the excitation spectrum in a "magnetized" phase clearly possesses a two-branch and roton-maxon structure. Expand
On-Demand Single Photons with High Extraction Efficiency and Near-Unity Indistinguishability from a Resonantly Driven Quantum Dot in a Micropillar.
TLDR
By s-shell pulsed resonant excitation of a Purcell-enhanced quantum dot-micropillar system, deterministically generate resonance fluorescence single photons which, at π pulse excitation, have an extraction efficiency of 66, single-photon purity of 99.1%, and photon indistinguishability of 98.5%. Expand
Quantum computational advantage using photons
TLDR
Gaussian boson sampling was performed by sending 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random matrix and sampling the output using 100 high-efficiency single-photon detectors, and the obtained samples were validated against plausible hypotheses exploiting thermal states, distinguishable photons, and uniform distribution. Expand
Decoy-state quantum key distribution with polarized photons over 200 km.
TLDR
A novel and economic way of synchronization method is designed and incorporated into the system, which allows to work at a low frequency of 40kHz and removes the use of highly precise clock. Expand
