Matchgate quantum computing with cold polar molecules

What is it about?

Polar molecules in optical lattices are ideal candidates for building a quantum computer, but so far it has been difficult to achieve this goal experimentally, in part due to the very large dc electric fields required to implement quantum gates. We introduce a molecular two-qubit gate implementation that only requires infrared laser pulses and dc magnetic fields, and show that the scheme is robust with respect to realistic experimental imperfections. This work opens the way to new quantum control experiments with cold polar molecules.
