In the strange world of quantum physics, even the tiniest tweak can unlock outsized rewards.

Quantum technologies demand perfection: one photon at a time, every time, all with the same energy. Even tiny deviations in the number or energy of photons can derail devices, threatening the ...

Quantum information can be carried in particles of light called photons. Single photon emitters that emit precisely one photon at a time are important components for many quantum technologies, ...

The ability to control the colour, or emission wavelength, of light from quantum sources is central to the development of secure quantum communication networks and photonic-based computing. However, ...

A U.S. Naval Research Laboratory (NRL) multi-disciplinary team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic ...

Quantum light sources often produce inconsistent or contaminated single photons, limiting the reliability of quantum technologies. Researchers coated atomically thin tungsten diselenide with a uniform ...
