The ultrafast nature of the cat generation is less restrictive on nonlinearities in the forces on the atom, and allows for very fast state creation with Δα = 0.4 per laser pulse period (~12 ns). Fina
Figure 3: Light-atom interaction. (a) Measurement of the probability P↓ of finding the spin in the |↓〉 state as a function of the interaction time with light near-resonant with the sth motional sideband and of the trap-potential displacement xd. The minimum pulse time is tp=1.4 μ...
follows the voltage of an external voltage source. Depending on the application, a high RC time constant can be desired to be able to sweep a voltage pulse over the entire gate area, similar to U.S. Pat. No. 5,528,643 but without complex clocking schemes and circuitry and with the pos...
To explore the effect of an error in π pulse area on a gate applied to an adjacent pair of ions in a large trap, we employed a method relying on the assumption that the motional mode dynamics are separable during the gate, a valid assumption for small π pulse errors in harmonic ...
