Diamond Quantum Technologies

Authors: George Rajna

Qubits from diamonds are of particular interest to quantum scientists because their quantum-mechanical properties, including superposition, exist at room temperature, unlike many other potential quantum resources. [31] For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. [30] Diamonds are prized for their purity, but their flaws might hold the key to a new type of highly secure communications. [29] Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4000 kilometre fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. [28] Researchers at the University of York have shown that a new quantum-based procedure for distributing secure information along communication lines could be successful in preventing serious security breaches. [27] In the new study, Bomantara and Gong have developed a method for harnessing the unique properties of time crystals for quantum computing that is based on braiding. [26] An Aalto University study has provided new evidence that time crystals can physically exist-a claim currently under hot debate. [25] Yale physicists have uncovered hints of a time crystal-a form of matter that "ticks" when exposed to an electromagnetic pulse-in the last place they expected: a crystal you might find in a child's toy. [24] The research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways. [23]
