Collective quantum entanglement from induced dark states is inherently resistant to external disturbances and exhibits 600X longer lifetimes

"near-total invisibility to emitted light allows entanglement to persist... creating dark states: nanocavity with tuned loss rates balancing coupling strength between quantum dots/ cavity's dissipation... when cavity loss too high, quantum dots act independently without affecting each other/ if coupling sufficiently strong, collective entangled state formed... entanglement lasts up to 36 ns... quantum: ultra-sensitive sensors, memory/ transmission, energy-harvesting technologies based on quantum principles"
