"lasers tune entanglement interaction of ions in vacuum producing squeezed quantum state... interaction between neighboring particles decreases with distance between particles, spin-exchange interactions more collective behavior... measurement errors halved by entangling 51 ions in relation to individual particles... quantum entanglement makes sensors even more sensitive... satellite-based navigation or data transfer... search for dark matter or determination of time-variation fundamental constants... atomic clocks"
