Lifetime-Limited Interrogation of Two Independent Clocks Using Correlation Spectroscopy
E. R. Clements, M. E. Kim, K. Cui +7
Laser decoherence limits the stability of optical clocks by broadening the observable resonance linewidths and adding noise during the dead time between clock probes. Correlation s…
Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
T. M. Fortier, C. W. Nelson, A. Hati +10
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we d…
Quantum coherence between two atoms beyond Q=10^15
C. W. Chou, D. B. Hume, M. J. Thorpe +2
We place two atoms in quantum superposition states and observe coherent phase evolution for 3.4x10^15 cycles. Correlation signals from the two atoms yield information about their r…
Preparation of Dicke States in an Ion Chain
D. B. Hume, C. W. Chou, T. Rosenband +1
We have investigated theoretically and experimentally a method for preparing Dicke states in trapped atomic ions. We consider a linear chain of ion qubits that is prepared in a…
