For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but ...

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 ...

Physicists have recreated the Nobel Prize–winning quantum Hall effect using light, revealing that photons can follow the same ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

Scientists have developed a new way to manufacture semiconductor quantum dots that emit faster ...

A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

Physicists have forced light to behave like electrons trapped in a magnetic field, producing a quantized sideways drift that had never been observed in photons before. The experiment, carried out on ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is that a malicious third party could steal the key by hacking the devices the ...
