Controlling Quantum Emitters Remotely
Remote control for quantum emitters Quantum technologies are enabled by precise control of the state and interactions of individual quantum objects. Innsbruck physicists have now proposed a way to remotely control the state of individual quantum emitters. The underlying idea, developed by a research group led by Oriol Romero-Isart, is based on chirped light pulses. […]
Australia: University of Queensland Introduces 20 Dimensional Quantum State, The Quvigint
Finding quvigints in a quantum treasure map Researchers have struck quantum gold—and created a new word—by enlisting machine learning to efficiently navigate a 20-dimensional quantum treasure map. Physicist Dr Markus Rambach from the ARC Centre of Excellence for Engineered Quantum Systems (EQUS) at The University of Queensland said the team was able to find unknown quantum […]
Columbia Engineering Pushes Forth In Many Quantum Directions With New Twistoptics Studies
Twistoptics—A New Way to Control Optical Nonlinearity Two slabs of boron nitride crystals are dynamically twisted with respect to each other. At certain angles, the incoming laser light (orange beam) can be efficiently converted to higher energy light (pink beam), as a result of micromechanical symmetry breaking. Nonlinear optics, a study of how light […]
