Direct measurement of the 3P0 clock state natural lifetime in 87Sr
Jonathan Dolde, Dhruva Ganapathy, Xin Zheng +3
Optical lattice clocks based on the narrow (5s2)1S0 - (5s5p)3P0 transition in neutral strontium (Sr) are among the most precise and accurate measurement devices in existence. Altho…
Enhancing optical lattice clock coherence times with erasure conversion
Shuo Ma, Jonathan Dolde, Xin Zheng +6
Increasing coherent interrogation times is central to advancing the precision of optical clocks. Synchronous differential optical clock comparisons have now demonstrated atomic coh…
Quantum Sensing with Erasure Qubits
Pradeep Niroula, Jack Dolde, Xin Zheng +7
The dominant noise in an "erasure qubit" is an erasure -- a type of error whose occurrence and location can be detected. Erasure qubits have potential to reduce the overhead associ…
Reducing the instability of an optical lattice clock using multiple atomic ensembles
Xin Zheng, Jonathan Dolde, Shimon Kolkowitz
The stability of an optical atomic clock is a critical figure of merit for almost all clock applications. To this end, much optical atomic clock research has focused on reducing cl…
A lab-based test of the gravitational redshift with a miniature clock network
Xin Zheng, Jonathan Dolde, Matthew C. Cambria +2
Einstein's theory of general relativity predicts that a clock at a higher gravitational potential will tick faster than an otherwise identical clock at a lower potential, an effect…
High precision differential clock comparisons with a multiplexed optical lattice clock
Xin Zheng, Jonathan Dolde, Varun Lochab +3
Rapid progress in the precision and accuracy of optical atomic clocks over the last decade has advanced the frontiers of timekeeping, metrology, and quantum science. However, the s…
Impacts of random filling on spin squeezing via Rydberg dressing in optical clocks
Jacques Van Damme, Xin Zheng, Mark Saffman +2
We analyze spin squeezing via Rydberg dressing in optical lattice clocks with random fractional filling. We compare the achievable clock stability in different lattice geometries,…
