Scientists Manipulate Quantum Fluids of Light, Bringing us Closer to Next-Generation Unconventional Computing
With this development, scientists now have the power to design all-optical polariton logic devices that harness the benefits of ultrafast microcavity refractive index modulation as another independent, real-time tuning parameter.

In a quantum leap toward the future of unconventional computing technologies, a team of physicists made an advancement in spatial manipulation and energy control of room-temperature quantum fluids of light, aka polariton condensates, marking a pivotal milestone for the development of high-speed, all-optical polariton logic devices that have long held the key to next-generation unconventional computing, according to a recently published paper in Physical Review Letters.
Polaritons, hybrid particles formed by the coupling of light and matter, are usually described as a quantum fluid of light that one can control through its matter component. Now, researchers have taken a monumental step forward by introducing a novel approach for active spatial control of liquid light condensates at room temperature.
