Measurement-induced long-range entanglement in a hot, strongly-interacting atomic system

April 2019. The ICFO team has used quantum non-demolition (QND) measurement to generate long-lived, long-range entanglement in a dense, hot, strongly-interacting atomic system [1]. This implements a central element of proposals for detection [2-4] and production [5] of complex anti-ferromagnetic phases. The resulting entangled state is exceptionally resistant to thermal decoherence, and shares several traits... Continue Reading →
