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 ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

Quantum physics keeps challenging our intuition. Researchers have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough ...

A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

WEST LAFAYETTE, Ind. — Caltech president and pioneering physicist Thomas Rosenbaum, an expert in the promising field of quantum physics, will join Purdue University President Mung Chiang in April for ...

IBM unveiled what it calls the first integrated quantum computing system for commercial use. 1. Quantum computing is meant to help researchers investigate problems that are too complex for classical ...

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 ...
