Neither classical nor quantum: This computer lets light solve complex calculations

Queen's University researchers developed a computer that uses light pulses instead of electronics to solve complex optimization problems that overwhelm traditional computers. Built from ordinary internet components like fiber-optic cables and lasers, the room-temperature machine represents problems as interacting light pulses that naturally settle into optimal solutions, similar to how magnets align in physics. The system handles up to 256 fully connected variables, remains stable for hours, and dramatically outperforms other optical computers while consuming less energy than conventional supercomputers.
