A quantum harmonic oscillator—a structure that can control the location and energy of quantum particles that could, in the future, be used to develop new technologies including OLEDs and miniature lasers—has been made at room temperature by researchers led by the University of St Andrews.
The research, conducted in collaboration with scientists at Nanyang Technological University in Singapore and published in Nature Communications recently, used an organic semiconductor to produce polaritons, which show quantum states even at room temperature.
