About

William Coish is a theoretical physicist who investigates nanoscale systems – electronic devices with a size scale of a few billionths of a metre.

At these tiny length scales, the laws of quantum, rather than classical, mechanics hold sway. Devices that obey quantum principles could drastically accelerate computational tasks and allow for highly secure private communication. Coish works on fundamental problems related to the physics of decoherence (the loss of information stored in quantum devices); the creation of entanglement (strong correlations between quantum particles, necessary to improve communication tasks); and the coupling of distant quantum systems with light, a prerequisite for large-scale computation with quantum devices.
