Prof. Chris Monroe, JQI and University of Maryland
“Building a Quantum Computer, Atom by Atom”
Laser-cooled and trapped atomic ions are standards for quantum information science, acting
as qubits with unsurpassed levels of quantum coherence while also allowing near-perfect
measurement. When qubit state-dependent optical forces are applied to a collection of
ions, their Coulomb interaction is modulated in a way that allows entanglement operations
that form the basis of a quantum computer. Similar forces allow the simulation of quantum
magnetic interactions, and recent experiments have implemented tunable long-range
interacting spin models with up to 40 trapped ions. Scaling to even larger numbers can be
accomplished by coupling trapped ion qubits to optical photons, where entanglement can be
formed over remote distances for applications in quantum communication, quantum
teleportation, and distributed quantum computation. By employing such a modular and
reconfigurable architecture, it should be possible to scale up ion trap quantum networks
to useful dimensions, for future quantum applications that are impossible using classical
processors.
