A Quantum computer based on trapped ions

Trapped ions are a promising candidate system to realize a scalable quantum computer. We present a modular quantum computing architecture comprised of a chain of single 171Yb+ ions with individual laser beam addressing and readout [1]. We use the transverse modes of motion in the chain to produce entangling gates between any qubit pair. This creates a fully connected system which can be configured efficiently to run any sequence of single- and two-qubit gates [2], making it in effect an arbitrarily programmable quantum computer.
Recent results from different quantum algorithms with five and seven qubits will be presented [3], including a probe into the black-hole information paradox. I will also discuss schemes to scale up this architecture.
