Floquet Topological Insulators

Researchers at the Joint Quantum Institute (JQI) and the California Institute of Technology have shown that it may be possible to take a conventional semiconductor and endow it with topological properties without subjecting the material to extreme environmental conditions or fundamentally changing its solid state structure. In their Nature Physics (appeared online March 13, 2011) article titled “Floquet topological insulators in ...

JQI Physicists Demonstrate Coveted ‘Spin-Orbit Coupling’ for the First Time in Ultracold Atomic Gases

Physicists at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park, have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling.

NIST Researchers Create 'Quantum Cats' Made of Light

Researchers at the National Institute of Standards and Technology (NIST) have created "quantum cats" made of photons (particles of light), boosting prospects for manipulating light in new ways to enhance precision measurements as well as computing and communications based on quantum physics.

The NIST experiments, described in a forthcoming paper co-authored by JQI fellow Alan Migdall,* repeatedly produced light pulses ...

A New Design for a Gravimeter

Scientists have developed a novel design for a highly compact, ultra-sensitive quantum device to measure subtle changes in gravity over very short time or distance scales.*

Tools of this sort – called atom interferometers (AIs) – are now used to search for natural resources beneath the Earth’s surface, navigate deep underwater or in the air, and measure Newton’s gravitational constant ...

Ultrafast Gates for Single Atomic Qubits

A team of physicists has achieved ultrafast “switching” time in an operation central to quantum information processing, changing the state of a single trapped ion in less than 50 picoseconds (10-12, or trillionths of a second) with more than 99 percent reliability. That is the fastest time on record – by a factor of about 1,000—for ion “gates,” which may ...

Anatomy of a Phase Shift

Researchers studying a gas of trapped ultracold atoms have identified a set of conditions, never before observed but in excellent agreement with new theoretical predictions, that determine the onset of a critical “phase transition” in atomic arrays used to model the behavior of condensed-matter systems. 

The findings provide a novel insight into the way collections of atoms suddenly cease to ...

JQI Wins Atomtronics MURI Award

Joint Quantum Institute (JQI) scientists have won a highly sought-after MURI award from the U.S. Department of Defense -- one of 32 projects selected for funding in the FY 2010 nationwide competition. The Pentagon will provide a total of $227 million over five years to awardees in the annual Multidisciplinary University Research Initiative (MURI) program, whose winners were chosen from ...
