The Quantum Observer

Diamond is famous in material science for being the best natural heat conductor on Earth—but new research reveals that, at the atomic scale, it can briefly trap heat in unexpected ways. The findings could influence […]

A researcher at the Department of Physics at Tohoku University has uncovered a surprising quantum phenomenon hidden inside ordinary crystals: the strength of interactions between electrons and lattice vibrations—known as phonons—is not continuous, but quantized. […]

Traveling-wave parametric amplifiers (TWPAs) are electronic devices that boost weak microwave signals (i.e., electromagnetic waves with frequencies typically ranging between 1 and 100 GHz). Recently, many engineers have been developing TWPAs based on superconductors, materials […]

Scientists from the Indian Institute of Technology Bombay have found a way to use light to control and read tiny quantum states inside atom-thin materials. The simple technique could pave the way for computers that […]

Quantum technologies from ultrasensitive sensors to next-generation information processors depend on the ability of quantum bits, or qubits, to maintain their delicate quantum states for a sufficiently long time to be useful. Click to rate […]

Reliably quantifying and characterizing the quantum states of various systems is highly advantageous for both quantum physics research and the development of quantum technologies. Quantifying these states typically entails performing several measurements and reconstructing them […]
