Quantum Mechanics survives a gravity test in space

Scientists have challenged one of the great mysteries of physics – by undertaking an experiment in space proposed by The University of Queensland a decade ago. The School of Mathematics and Physics’ Professor Timothy Ralph collaborated on the study, which he said could bring quantum technologies, such as a global quantum internet, closer to being … Read more

Light surfing

A similar situation occurs when a light pulse interacts in a material with a moving front of refractive index as shown in Fig. 2. In this case, no friction needs to be overcome and the extracted energy from the front is used instead to change the color (frequency) of the light. Experienced surfers can balance … Read more
