Quantum Communications Bend to Our Needs

APL017737-Olbrich-photons.jpg

The potential for photon entanglement in quantum computing and communications has been known for decades. One issue impeding immediate application is that many photon entanglement platforms do not operate within the range used by most forms of telecommunication. Researchers have started to unravel the mysteries of entangled photons, demonstrating a new nanoscale technique that uses semiconductor quantum dots to bend photons to the wavelengths used by today’s popular C-band standards. They report their work in Applied Physics Letters.

Enhancing the Sensing Capabilities of Diamonds with Quantum Properties

APL018735-Farfunik-diamond-cropped.jpg

When a nitrogen atom is next to the space vacated by a carbon atom, it forms what is called a nitrogen-vacancy center. Now, researchers have shown how they can create more NV centers, which makes sensing magnetic fields easier, using a relatively simple method that can be done in many labs. They describe their results this week in Applied Physics Letters.

Massive Particles Test Standard Quantum Theory

PressreleaseCotter.jpg

In quantum mechanics particles can behave as waves and take many paths through an experiment, even when a classical marble could only take one of them at any time. However, it requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive somewhere. This principle is a consequence of Born’s rule, a cornerstone of quantum physics and any measured violation of it might hint at new physics. Now, researchers at the Universities of Vienna and Tel Aviv have addressed this question for the first time explicitly using the wave interference of large molecules behind various combinations of single, double, and triple slits. The analysis – published in the Journal ‘Science Advances’ – confirms the formalism of established quantum physics for massive particles.
