Nanofibers and Designer Light Traps

In this experiment, physicists squeeze combinations of higher modes of the light into a nanofiber with unprecedented efficiency and purity. This kind of control may translate into more control over evanescent atom traps

Topological Light

In this week’s issue of Nature Photonics scientists at the Joint Quantum Institute (*) report the first observation of topological effects for light in two dimensions, analogous to the quantum Hall effect for electrons. To accomplish this, they built a structure to guide infrared light over the surface of a room temperature, silicon-on-insulator chip.

Photons a la Mode

The photodetectors in Alan Migdall’s lab often see no light at all, and that’s a good thing since he and his JQI (*) colleagues perform physics experiments that require very little light, the better to study subtle quantum effects. Their latest achievement, described here, is to develop a new way of counting photons to understand the sources and modes of light in modern physics experiments.

Resonant Exchange Qubits

Unfortunately, qubits are fragile; they dissipate in the face of interactions with their environment. A new JQI semiconductor-based qubit design ably addresses this issue of qubit robustness.

Quantum Information in Low Light

JQI researchers in the lab of Alan Migdall, demonstrate how one category of photo-detection system can make highly accurate readings of incoming information at the single-photon level by allowing the detector in some instances not to give a conclusive answer.

Spin Hall Effect in a Quantum Gas

JQI Researchers have reported* the first observation of the "spin Hall effect" in a Bose-Einstein condensate.This is a step toward applications in "atomtronics"—the use of ultracold atoms as circuit components.

Entanglement in a Flash

JQI researchers under the direction of Chris Monroe have produced quantum entanglement between a single atom’s motion and its spin state thousands of times faster than previously reported, demonstrating unprecedented control of atomic motion.
