Quantum Sails

Quantum sails are a theoretical propulsion concept that use the pressure of light or other electromagnetic radiation to propel a spacecraft. Unlike traditional sails that rely on sunlight reflecting off a large fabric surface, quantum sails would harness quantum phenomena—such as the interaction of particles with engineered materials—to generate thrust efficiently at very small scales. This approach could potentially enable deep space travel with minimal fuel. While still in the research stage, quantum sails represent a promising avenue for future spacecraft propulsion, leveraging advanced physics to explore the cosmos more sustainably and rapidly.
