Spin gradient thermometry for ultracold atoms in optical lattices

A major goal of current research with ultracold atoms in optical lattices is the realization of magnetic ordering.  This requires temperatures on the order of the second order tunneling rate, J2/U where U is the interaction energy and J the tunneling amplitude.  Such temperatures are about ten times less than 1 nk, the lowest temperature...

Universal resource state for One-Way Quantum Computations

A fascinating model for quantum computing, other than the traditional quantum circuit model, is the “one-way” model that is based on simply doing single qubit measurements to a fixed, initial entangled quantum state of many qubits.  By feeding back measurement results to control the axis of subsequent measurements, any quantum circuit can be simulated and...

Realization of high selectivity ion qubit addressing scheme

Selectively addressing individual qubits in an array of ions is a vital task for scalable quantum computation with trapped ions.  Traditionally, this is accomplished using complex optics for laser beam steering, but such schemes are not easily scalable.  We have realized a scalable alternative which employs the advantages of microfabrication and cryogenic operation, and applies...
