Co-trapping of Cold NH Molecules with N Atoms

A frontier in physics with cold polar molecules is the study of paths toward collisional cooling. Here we co-trap an very low polarizability atom along with a very “atom-like” polar molecule. Earlier work with He colliding with NH found that the inelastic processes were highly suppressed due to the small of the NH ground state...

Realization of a strongly interacting Bose-Fermi mixture from a two-component Fermi gas

Fermions are the fundamental building blocks of matter, whereas bosons emerge as composite particles. The simplest physical system to study the emergence of bosonic behavior is a two-component fermion mixture, where the composite boson is a dimer of the two different fermions.

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.
