Two-photon emission is a relatively weak emission process, about five orders of magnitude weaker than the usual single-photon emission that occurs in semiconductor lasers or LEDs. So we had to use ...

Researchers have experimentally demonstrated a groundbreaking quantum imaging method using ultra-thin nonlinear metasurfaces.

Researchers have developed a method that leverages artificial intelligence to ensure accurate heart scans without added radiation or cost.

Coronary artery disease is the leading cause of death globally. One of the most common tools used to diagnose and monitor ...

Scientists have created an ultra-thin metasurface that generates entangled photons for quantum imaging, offering up to four ...

Coronary artery disease is the leading cause of death globally. One of the most common tools used to diagnose and monitor heart disease, myocardial perfusion imaging (MPI) by single photon emission ...

In an advance for quantum technologies, researchers at the Cavendish Laboratory, University of Cambridge, have created a ...

Scientists successfully used 13,000 nuclear spins in a gallium arsenide (GaAs) quantum dot system to create a scalable ...

As a result, rather than emitting a photon, a defect might instead cause the atoms to vibrate, reducing the light-emission efficiency. Chris G. Van de Walle, Herbert Kroemer Professor, Materials ...

The metasurface generates spatially entangled photon pairs, with their emission angle tunable via the pump laser wavelength. Using these photon pairs, quantum imaging with unprecedented resolution ...
