The First Controllable Atom SQUID

PFC-supported scientists at JQI have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular quantum state of the system at will.

Vive la Francium

In September 2012 an experiment at the TRIUMPH accelerator complex reached a milestone. The FrPNC collaboration succeeded in trapping several kinds of francium, including the isotope Fr-207, which had never before been trapped.

Topological Superconductors

Theoretical physicists at the JQI have done an important step forward to understand qubits in a real-world setup. In a new study they show, for the first time, that qubits can successfully exist in a so called topological superconductor material even in the presence of impurities in the material and strong interactions among participating electrons.

Quantum Longitude

“Quantum weirdness,” a phrase related to the power and the un-intuitive nature of quantum reality, is expected to facilitate speeded-up computation -- quantum computing -- for performing certain specialized tasks, such as factoring numbers. A proposed scheme should be helpful in sustaining coherence by carefully making mid-calculation corrections.

The unit cell for “spin ice” materials consists of two tetrahedrons. The arrows show the orientation of the magnetic atoms within the material.

Freezing Magnetic Monopoles

Stephen Powell, a scientist at the JQI, has sharpened the theoretical framework under which magnetic monopoles (entities with isolated north or south magnetic poles) can operate.

Seeing the Light with NIST's New Noiseless Optical Amplifier

Scientists working at the JQI and NIST have demonstrated that they can amplify weak light signals without adding noise while also carrying more information—more pixels—than other low-noise amplifiers.

Disorderly Conduct in Quantum Coherence

A new experiment conducted at the JQI examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections in those materials.

First Observation of the Hall Effect in a Bose-Einstein Condensate

NIST researchers have observed for the first time the Hall effect in a gas of ultracold atoms.
