Microfabricated Ion Trap Systems for Quantum Simulations

We have developed and tested a generation of ion traps, for the purpose of quantum information science and quantum simulations. These traps are based on semiconductor lithography, fabricated at MIT, and operated at liquid helium temperature. The traps enable systematic study of the behavior of the quantum state of trapped ions, near the surface of...

Spin Squeezing on an Atomic Clock Transition

Atomic clocks, the most accurate instruments ever developed, can now operate at the Standard Quantum Limit; their uncertainty dominated by the uncorrelated projection of individual atoms into eigenstates.  Using entanglement, quantum mechanics allows one to correlate the atoms so as to redistribute or squeeze such quantum noise, reducing the uncertainty in a variable of interest.

Phase diagram of a two-component Fermi gas with resonant interactions

The pairing of fermions is at the heart of superconductivity and superfluidity.  The stability of these pairs determines the robustness of the superfluid state, and the quest for superconductors with high critical temperature is a search for systems with strong pairing mechanisms. Ultracold atomic Fermi gases have emerged as a highly controllable model system for...
