diamondsQuantum Control in Nanodiamonds

Quantum coherence control usually requires low temperature environments. Even for nitrogen-vacancy center spins in diamond, a remarkable exception, the coherence signal is limited to about 700 K due to the quench of the spin-dependent fluorescence at a higher temperature. Here …

diamondsUnder the continental plates are 1000 trillion tons of diamonds

A new study suggests that 120 to 150 kilometers (75 to 93 miles) under the Earth’s surface there is 1000 trillion tons of diamonds. The diamonds are in the “roots” of cratons, which are large sections of rock. Cratons lie …

diamondsPractical Continuous Room Temperature Masers using Diamonds

Physicists at Imperial College London can now produce a continuous maser beam in room-temperature conditions. The set-up involves shining a laser light through a diamond, sapphire and copper apparatus to create the microwave emission. The sensitivity of existing microwave amplifiers …

diamondsExoplanet space telescope will launch in December 2017

The Transiting Exoplanet Survey Satellite (TESS) is a planned space telescope for NASA’s Explorers program, designed to search for exoplanets using the transit method. It is planned for launch in December 2017. The primary mission objective for TESS is to …
