Efficient Measurement of Multiparticle Entanglement with Embedding Quantum Simulator

2016 · Physical Review Letters

The quantum measurement of entanglement is a demanding task in the field of quantum information. Here, we report the direct and scalable measurement of multiparticle entanglement with embedding photonic quantum simulators. In this embedding framework …

Multi-photon quantum boson sampling on a semiconductor (Conference Presentation)

2018

Boson sampling is considered as a strong candidate to demonstrate the “quantum advantage / supremacy” over classical computers. However, previous proof-of-principle experiments suffered from small photon number and low sampling rates owing to the inefficiencies …

Quantum Interference between Light Sources Separated by 150 Million Kilometers

2019 · Physical Review Letters

We report an experiment to test quantum interference, entanglement, and nonlocality using two dissimilar photon sources, the Sun and a semiconductor quantum dot on the Earth, which are separated by ∼150 million kilometers. By making …

Emergence of Classical Objectivity of Quantum Darwinism in a Photonic Quantum Simulator

2018 · arXiv (Cornell University)

Quantum-to-classical transition is a fundamental open question in physics frontier. Quantum decoherence theory points out that the inevitable interaction with environment is a sink carrying away quantum coherence, which is responsible for the suppression of …

Gaussian Boson Sampling with Pseudo-Photon-Number-Resolving Detectors and Quantum Computational Advantage

2023 · Physical Review Letters

We report new Gaussian boson sampling experiments with pseudo-photon-number-resolving detection, which register up to 255 photon-click events. We consider partial photon distinguishability and develop a more complete model for the characterization of the noisy Gaussian …
