What are we trying to do?What are we trying to do?
Create a world-class partnership between Create a world-class partnership between NIST, LPS and UM NIST, LPS and UM on the Maryland on the Maryland CampusCampus
Cover the complete field of quantum Cover the complete field of quantum coherence (and quantum computing) coherence (and quantum computing)
Make this a center which attracts the top Make this a center which attracts the top scientists in the world scientists in the world
Start with a JILA model, but strongerStart with a JILA model, but stronger
Why now?Why now?Recent advances in both Condensed Matter and AMO have enabled unprecedented quantum coherence, with exciting prospects for applications. The new center would join the efforts and the insights to exploit coherence in solid state and atomic systems.
We have tremendous strength in our existing groups in this area
We have a new AMO group with strong ties to NIST
Now during the budget crunch is the perfect time to make a big move
This is a strong motivating force for the PSC
The leadership of every organization is highly supportive
Coherence is the Key
Interference of two atomic-gas Bose condensates

• Nuclear spins flip-flop due to their dipolar interaction;
• Electron’s Zeeman frequency fluctuates in time due to nuclear hyperfine field.
Nuclear pairs are described by Poisson random variables;
Flip-flop rates are calculated using the method of moments, a high temperature expansion.
