Physicists Aim to Make Transition to Quantum World Visible

Physicists Aim to Make Transition to Quantum World Visible

Theoretical physicist Frank Wilhelm-Mauch and his research team at Saarland University have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into the world of quantum particles. The new test system will enable the simultaneous study of one hundred light quanta (photons) and their complex quantum […]

Topological Light: Living On the Edge

Topological Light: Living On the Edge

Topology — the understanding of how things are connected — remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because it is the basis for creating ultrastable quantum “playgrounds.” In topological systems, certain quantum behaviors can be carefully probed and even harnessed for […]

Flawed Diamonds: Gems for New Technology

Flawed Diamonds: Gems for New Technology

A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers — defects in which two adjacent carbon atoms in the diamond’s crystal structure are replaced by a single nitrogen atom and an empty gap.   These […]

Physicists ‘Entangle’ Microscopic Drum’s Beat With Electrical Signals

Physicists ‘Entangle’ Microscopic Drum’s Beat With Electrical Signals

Extending evidence of quantum behavior farther into the large-scale world of everyday life, physicists at the National Institute of Standards and Technology (NIST) have “entangled” — linked the properties of — a microscopic mechanical drum with electrical signals.   The results confirm that NIST’s micro-drum could be used as a quantum memory in future quantum […]

Measuring Height by Connecting Clocks

Measuring Height by Connecting Clocks

How far above sea level is a place located? And where exactly is “sea level”? It is one objective of the geodesists to answer these questions with 1 cm accuracy. Conventional measurement procedures or GPS technologies via satellites, however, reach their limits here. Now optical atomic clocks offer a new approach, because the tick rate […]

Superfast Switching of Quantum Light Sources

Superfast Switching of Quantum Light Sources

Usually, an elementary light source — such as an excited atom or molecule — emits light of a particular color at an unpredictable instance in time. Recently, however, scientists from the MESA+ Institute for Nanotechnology of the UT, FOM and the Institute for Nanoscience and Cryogenics (CEA/INAC) in France have shown that a light source […]
