A large scale quantum computer will require optical interconnects, regardless of the qubit platform, thus allowing a modular architecture with full connectivity. Atomic systems are natural memory nodes for photonic interfaces, especially atomic ions, which already feature high-performance local quantum gates and near-perfect initialization and measurement. There are several atom/photon interface prototols for heralded remote entanglement using photonic qubits encoded in polarization, frequency, or time-bin. [more]

The universe has evolved from a far-from-equilibrium state post Big Bang. High-energy particle colliders stride to recreate such nonequilibrium conditions in experiment, to reach densities and temperatures necessary for generating some of the most short-lived states of matter, and to unravel equilibration and hadronization mechanisms. Theoretical studies of matter out of equilibrium, rooted in the fundamental gauge theories of nature, often require simulations that are intractable with classical computing. [more]
