Quantum technologies, devices that perform specific functions leveraging quantum mechanical effects, could soon outperform ...

The 2023 Nobel Prize in Chemistry was focused on quantum dots -- objects so tiny, they're controlled by the strange rules of quantum physics. Quantum dots used in electronics are often toxic, but ...

Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber ...

Work on tiny dots that light up TV screens and help doctors see the blood vessels that feed tumors has earned three scientists the 2023 Nobel Prize in chemistry. Chemist Moungi Bawendi, chemist Louis ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now ...
