  We propose a new technique for detecting gravitational waves using Quantum
Entangled STate (QUEST) technology. Gravitational waves reduce the non-locality
of correlated quanta controlled by Bell's inequalities, distorting quantum
encryption key statistics away from a pure white noise. Gravitational waves
therefore act as shadow eavesdroppers. The resulting colour distortions can, at
least in principle, be separated from noise and can differentiate both
deterministic and stochastic sources.
