Using Lieb-Mattis states, a new entanglement-enhanced protocol for differential phase sensing in two-node quantum sensor networks is immune to common-mode noise but robust to local imperfections. The work introduces a unitary and dissipative protocol.

ALT Figure showing the differential phase sensing protocol in three parts. The top schematic shows how the atoms in ensembles are initially in their excited ground states, shown by globes with colorful areas on one of the poles. An entangler is applied, causing each to acquire a distinct phase, shown by horizontal arrows on the globes. Then a joint measurement estimates the differential phase for each. The second schematic shows the target state after the entangling process, which is an entangled Lieb-Mattis state. The last part of the figure shows the Wigner distributions represented by globes with colorful areas and alternating signs of all Dicke-state combinations.

A team led by JILA and @NIST Fellow Jun Ye has demonstrated a new way to boost clock precision using quantum entanglement. By making atoms "tick" in tighter unison, theyāve reduced the randomness that typically limits time measurement.
Their breakthrough surpasses the Standard Quantum Limit (SQL)āa fundamental threshold in quantum physicsāthanks to a method called spin entanglement. This advancement could enhance technologies like GPS, and deepen our understanding of gravity and the universe itself.

Researchers led by JILA and @NIST Fellow Jun Ye have shown how to make atomic clocks even more precise by leveraging entanglement. This allows the atoms to ātickā more in sync, reducing the randomness that usually limits how precisely we can measure time.
Their results show that itās possible to go beyond whatās known as theĀ Standard Quantum Limit (SQL)āa fundamental barrier in quantum measurementsāby using a technique calledĀ spin squeezing. This work could help improve everything from GPS systems to tests of gravity and the nature of the universe.
