Quantum Information Science & Technology

In January, we posted our first demonstration of a new concept for tweezer-programmable optical lattices. Using tweezers with spatial scale on the order of 400 nm, we can program the dynamics and Hamiltonian with single lattice site resolution. We use resolved-sideband cooling to prepare the atoms at extremely low temperatures. From these conditions, we demonstrate for the first time the implementation of a spatial search algorithm originally proposed by Childs and Goldstone. Andrew Childs collaborated with us on this project, and we expect interesting extensions down the line to multi-particle search algorithms.   

Q-FARM (Quantum Fundamentals, ARchitectures and Machines) is Stanford's initiative in quantum science and engineering.  The QFARM student fellowships are awarded to advanced graduate students working in quantum science and engineering.  Fellowship criteria are excellence in their research, and demonstrated potential for building new links within the Stanford quantum community.  Each awardee receives two years of funding.
