Dipolar exchange quantum logic gate with polar molecules

Quantum phase gate and controlled entanglement with polar molecules

Quantum magnetism with multicomponent dipolar molecules in an optical lattice.

We consider bosonic dipolar molecules in an optical lattice prepared in a mixture of different rotational states. The 1/R(3) interaction between molecules for this system is produced by exchanging a quantum of angular momentum between two molecules. We show that the Mott states of such systems have a large variety of quantum phases characterized by dipolar orderings including a state with an or...

Polar molecules in the quantum regime

May 2011 Physics Today 27 Molecules at ultralow temperatures represent an exciting new frontier for atomic, molecular, and optical physics; that frontier is endowed with a strong interdisciplinary character and connections to other scientific fields, including chemistry, quantum information, condensed-matter physics, and astrophysics.1 The connections, and many possibilities for technological a...

A Quantum Gas of Polar Molecules by

Far-from-equilibrium quantum magnetism with ultracold polar molecules.

Recent theory has indicated how to emulate tunable models of quantum magnetism with ultracold polar molecules. Here we show that present molecule optical lattice experiments can accomplish three crucial goals for quantum emulation, despite currently being well below unit filling and not quantum degenerate. The first is to verify and benchmark the models proposed to describe these systems. The s...
