MIT scientists built photonic ‘ski jumps’ that beam light off chips for faster quantum computing

MIT researchers developed photonic "ski jumps"—novel on-chip structures that efficiently launch light into free space, addressing a key bottleneck in quantum computing and optical communication systems. The breakthrough enables controlled, scalable light emission from photonic chips, where light typically remains trapped in tiny optical wires despite its speed advantages over electrical signals. Published in March 2026, the work targets quantum computing’s need for high-speed, low-loss light transmission between chips and external systems, a critical hurdle for scalable architectures. Unlike traditional methods, these structures use precision-engineered ramps to redirect light upward, minimizing energy loss and maintaining signal integrity for quantum information processing. The innovation could accelerate hybrid quantum-classical systems by bridging on-chip photonic circuits with off-chip components, reducing latency in quantum networks and optical interconnects.
