Atom–atom interactions around the band edge of a photonic crystal waveguide

A new paper by the Kimble group reports initial observation of cooperative atom–atom interactions around the band edge of a photonic crystal waveguide. "In recent years, there has been considerable effort to bring ultracold atoms into the realm of nanophotonics. Nanoscopic dielectric devices offer unprecedented opportunities to engineer novel capabilities for the control of atom–photon [...]

Derivations of the thermal state of a quantum system that has noncommuting charges

Recently reignited interest in quantum thermodynamics has prompted information-theoretic approaches to fundamental questions, including the roles of entanglement, measurement, and noncommutation. A central concept in statistical mechanics is the thermal state. The thermal state of a system that exchanges heat with a bath, or heat and particles, or other commuting observables, is well-known. But quantum [...]

Capturing Entanglement – a conversation with Stevan Nadj-Perge

Stevan Nadj-Perge, joined Caltech and IQIM in January as assistant professor of applied physics and materials science. "A large part of my research is focused on finding ways to store and process quantum information. Typically, if you have a quantum system, it loses its coherent properties—and therefore, its ability to store quantum information—very quickly. Quantum [...]
