A new piece of the quantum computing puzzle

Research from the McKelvey School of Engineering at Washington University in St. Louis has found a missing piece in the puzzle of optical quantum computing.

Generalizing the measurement postulate in quantum mechanics

The measurement postulate is crucial to quantum mechanics. If we measure a quantum system, we can only get one of the eigenvalues of the measured observable, such as position, energy and so on, with a probability. Immediately ...

Counting single photons at unprecedented rates

In high-end 21st century communications, information travels in the form of a stream of light pulses typically traveling through fiber optic cables. Each pulse can be as faint as a single photon, the smallest possible unit ...

Controlling fully integrated nanodiamonds

Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles—also known as quantum systems—makes possible a wide ...

Parylene photonics enable future optical biointerfaces

Carnegie Mellon University's Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He's labeled this new field of optical technology "Parylene photonics," ...

From custom-built to ready-made photonics

Information technology continues to progress at a rapid pace. However, the growing demands of data centers have pushed electrical input-output systems to their physical limit, which has created a bottleneck. Maintaining this ...

Geometry of intricately fabricated glass makes light trap itself

Laser light traveling through ornately microfabricated glass has been shown to interact with itself to form self-sustaining wave patterns called solitons. The intricate design fabricated in the glass is a type of "photonic ...
