A research team in China has built a quantum dot device that produces photon pairs with record-setting purity, achieving a two-photon fraction of 0.983(1). The work, published in Nature Materials, ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

Physicists at the University of the Witwatersrand in South Africa, together with colleagues from the Universitat Autònoma de Barcelona, have shown how ...

Researchers have discovered new ways to shape quantum light, creating high-dimensional states that can carry much more ...

Abstract: Single-Photon Avalanche Diodes (SPADs) are new and promising imaging sensors. These sensors are sensitive enough to detect individual photons hitting each pixel, with extreme temporal ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since ...

American culture has developed a curious habit of turning ordinary life into pathology. Shyness becomes social anxiety. Stress is labeled trauma. Sadness is quickly upgraded to depression. And now — ...

Wendy’s is helping people celebrate their single life the day after Valentine’s Day with a special dollar offer of its single burger. The company announced in a press release it is commemorating ...

Abstract: Silicon single-photon detectors (Si SPDs) play a crucial role in detecting single photons in the visible spectrum. For various applications, photon detection efficiency (PDE) is the most ...

A single trapped atom has been used to carry out Einstein’s proposed test of the double-slit experiment, a challenge he believed could expose a flaw in quantum mechanics by measuring its recoil The ...

A single trapped atom has now turned Einstein’s long-imagined moving-slit experiment into a physical reality, closing a nearly century-old gap in the debate over quantum mechanics. By carefully ...
