Researchers have built what they believe is 'the world's most efficient single-photon source.' And they are still improving it. With planned upgrades, the apparatus could generate upwards of 30 photons at unprecedented efficiencies. Sources of that caliber are precisely what's needed for optical quantum information applications.
Read moreA research team has invented a semiconductor quantum well system that can efficiently cool electronic devices using established fabrication methods. This work can allow for smaller and faster smart devices that consume less power.
Read moreResearchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. The approach could one day be used to create a large range of reconfigurable devices such as phase-shifters and tunable optical couplers needed for networking applications and quantum information processing.
Read moreQuantum physics is difficult and explaining it even more so. Researchers have now tried to solve one of the biggest puzzles in quantum physics: How to measure the quantum system without changing it?
Read moreThe quantum superposition principle has been tested on a scale as never before in a new study. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to interfere. By confirming this phenomenon — 'the heart of quantum mechanics', in Richard Feynman's words — on a new mass scale, improved constraints on alternative theories to quantum mechanics have been placed.
Read moreResearchers describe a noteworthy step forward in the quantum manipulation and control of light.
Read moreNew research result brings the quantum internet a step closer. Such an internet could offer the military security, sensing and timekeeping capabilities not possible with traditional networking approaches.
Read moreQuantum computing has the potential to revolutionize technology, medicine, and science by providing faster and more efficient processors, sensors, and communication devices. But transferring information and correcting errors within a quantum system remains a challenge. Researchers now demonstrate a new method of relaying information by transferring the state of electrons. The research brings scientists one step closer to creating fully functional quantum computers.
Read moreHey, physicists and materials scientists: You'd better reevaluate your work if you study iridium-based materials — members of the platinum family — when they are ultra-thin. Iridium 'loses its identity' and its electrons act oddly in an ultra-thin film when interfaced with nickel-based layers, which have an unexpectedly strong impact on iridium ions.
