When light strongly interacts with matter, it can produce unique quasi-particles called polaritons, which are half light and half matter. In recent decades, physicists explored the realization of polaritons in optical cavities ...
(Phys.org) —In the strange world of quantum mechanics, the vacuum state (sometimes referred to as the quantum vacuum, simply as the vacuum) is a quantum system's lowest possible energy state. While not containing physical ...
(PhysOrg.com) -- While researchers have already demonstrated the building blocks for few-bit quantum computers, scaling these systems up to large quantum computers remains a challenge. One of the biggest problems is developing ...
Researchers have discovered a way to "translate" quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking.

(Phys.org)—As understood in the field of quantum mechanics, objects are able to exist in more than one state at a time, a property known as superposition. Measuring such states is a challenge however, as doing so causes ...
(PhysOrg.com) -- A team of Finnish physicists has developed a novel way to amplify a microwave signal that unlike other amplifiers, produces noise that is just barely above that which is necessary due to the laws of quantum ...
(PhysOrg.com) -- Solar cells, the heart of the photovoltaic industry, must be tested for mechanical strength, oxidized, annealed, purified, diffused, etched, and layered.
