DESCRIPTION:Title: Beyond the Standard Quantum Limit in Atomic Clocks: Spi
 n Squeezing-Enhanced Precision at the 10-18 Level\n\nSpeaker: Maya Miklos
 \n\nAbstract: State-of-the-art optical clock comparisons are approaching 
 a fundamental precision limit due to the quantum fluctuations of uncorrel
 ated particles\, the Standard Quantum Limit (SQL). We demonstrate perform
 ance beyond the SQL at the 10-18 level in a strontium optical lattice clo
 ck integrated with a high-finesse optical cavity. With cavity-based quant
 um nondemolition measurements\, we prepare two independent spin-squeezed 
 ensembles of 30\,000 atoms each. A synchronous clock comparison with an i
 nterrogation time of 61 ms achieves a metrological improvement of 2.0(2) 
 dB beyond the SQL\, after correcting for state preparation and measuremen
 t errors. These results establish the most precise entanglement-enhanced 
 clock to date.\n\nhttp://next-to-u.app/events/46201f7a-71e0-4204-8b21-86c
