For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality.

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots—one of the biggest challenges in building a quantum ...

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...

The structure of the zinc oxide (ZnO) device. A two-dimensional electron gas (2DEG) forms at the (Mg, Zn)O/ZnO interface. By applying voltages to the gate electrodes, we can confine electrons in a ...

In one sentence: A quantum dot laser is a semiconductor laser whose gain medium contains nanoscale quantum dots that confine electrons and holes in all three dimensions, producing discrete energy ...

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 ...

Quantum dots are composed of semiconducting materials like cadmium selenide (CdSe) or indium arsenide (InAs) and can be synthesized through various methods. For instance, colloidal synthesis and ...

To get quantum computing to work, we will ultimately need lots of high-quality qubits, which we can tie together into groups of error-corrected logical qubits. Companies are taking distinct approaches ...

(Nanowerk News) Researchers have successfully created electrically defined quantum dots in zinc oxide (ZnO) heterostructures, marking a significant milestone in the development of quantum technologies ...
