Boson sampling with 20 input photons in 60-mode interferometers at state spaces

Hui Wang, Jian Qin, Xing Ding +11

Quantum computing experiments are moving into a new realm of increasing size and complexity, with the short-term goal of demonstrating an advantage over classical computers. Boson…

Analytical description of quantum emission in optical analogues to gravity

Maxime J Jacquet, Friedrich Koenig

We consider a moving refractive index perturbation in an optical medium as an optical analogue to waves under the influence of gravity. We describe the dielectric medium by the Lag…

Towards optimal single-photon sources from polarized microcavities

Hui Wang, Yu-Ming He, Tung Hsun Chung +21

An optimal single-photon source should deterministically deliver one and only one photon at a time, with no trade-off between the source's efficiency and the photon indistinguishab…

Exact Quantum Dynamics in Structured Environments

Dominic Gribben, Aidan Strathearn, Jake Iles-Smith +4

The dynamics of a wide range of technologically important quantum systems are dominated by their interaction with just a few environmental modes. Such highly structured environment…

Design of the coherent diffusive photon gun for generating non-classical states

Matthew Thornton, Anton Sakovich, Alexander Mikhalychev +4

We suggest and discuss a concept of deterministic integrated source of non-classical light based on the coherent diffusive photonics, a coherent light flow in a system of dissipati…

Photon-number parity of heralded single photons from a Bragg-reflection waveguide reconstructed loss-tolerantly via moment generating function

K. Laiho, M. Schmidt, H. Suchomel +6

Due to their strict photon-number correlation, the twin beams produced in parametric down-conversion (PDC) work well for heralded state generation. Often, however, this state manip…

Quantum interference between light sources separated by 150 million kilometers

Yu-Hao Deng, Hui Wang, Xing Ding +18

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…

Coherently driving a single quantum two-level system with dichromatic laser pulses

Yu-Ming He, Hui Wang, Can Wang +12

Efficient excitation of a single two-level system usually requires that the driving field is at the same frequency as the atomic transition. However, the scattered laser light in s…

Quantum Frequency Conversion of a Quantum Dot Single-Photon Source on a Nanophotonic Chip

Anshuman Singh, Qing Li, Shunfa Liu +10

Single self-assembled InAs/GaAs quantum dots are promising bright sources of indistinguishable photons for quantum information science. However, their distribution in emission wave…

On-demand semiconductor source of entangled photons which simultaneously has high fidelity, efficiency, and indistinguishability

Hui Wang, Hai Hu, T. -H. Chung +14

An outstanding goal in quantum optics and scalable photonic quantum technology is to develop a source that each time emits one and only one entangled photon pair with simultaneousl…

Quantum correlations in separable multi-mode states and in classically entangled light

Natalia Korolkova, Gerd Leuchs

In this review we discuss intriguing properties of apparently classical optical fields, that go beyond purely classical context and allow us to speak about quantum characteristics…

Optimal power generation using dark states in dimers strongly coupled to their environment

D. M. Rouse, E. M. Gauger, B. W. Lovett

Dark state protection has been proposed as a mechanism to increase the power output of light harvesting devices by reducing the rate of radiative recombination. Indeed many theoret…

Atom-only descriptions of the driven-dissipative Dicke model

François Damanet, Andrew J. Daley, Jonathan Keeling

We investigate how to describe the dissipative spin dynamics of the driven-dissipative Dicke model, describing two-level atoms coupled to a cavity mode, after adiabatic elimina…
