Time interfaces in materials with suddenly changing refractive indices create unique quantum optical phenomena including photon-pair production and destruction, tunable photon statistics, and opportunities for quantum state engineering.
Researchers have theorized a new mechanism to generate high-energy ‘quantum light’, which could be used to investigate new properties of matter at the atomic scale.
In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Researchers have developed an integrated electro-optic modulator that can efficiently change the frequency and bandwidth of single photons. The device could be used for more advanced quantum computing and quantum networks.
Researchers have designed smart, color-controllable white light devices from quantum dots — tiny semiconductors just a few billionths of a meter in size — which are more efficient and have better color saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.
Researchers at Karlsruhe Institute of Technology (KIT) and Chimie ParisTech/CNRS have now significantly advanced the development of molecule-based materials suitable for use as light-addressable fundamental quantum units. They have demonstrated for the first time the […]
Researchers unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements designed to evade the influence of the detector in the notorious ‘back action limit’ problem.
