JQI at Maryland Day 2015

Despite cold weather and cloudy skies, UMD's annual Maryland Day (April 25, 2015) attracted thousands of visitors eager to learn about the university. The JQI was again located on the lawn outside the Physics Building, and provided fun examples and analogs of quantum topics with demonstrations of parametric down conversion, wave-particle duality, charged dust traps, and the Meissner effect. The JQI thanks all of our volunteers for their hard work in making this day possible!

Tightening the Bounds on the Quantum Information 'Speed Limit'

If you’re designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but JQI physicists have narrowed the theoretical limits for where that “speed limit” is. The work implies that quantum processors will work more slowly than some research has suggested.  ...

Getting Better All the Time

From NIST TechBeat

In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology (NIST) researchers, the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would neither gain nor lose one second in some 15 billion years*—roughly the age of the universe. Precision timekeeping ...

A quantum sensor for nanoscale electron transport

The word “defect” doesn’t usually have a good connotation--often indicating failure. But for physicists, one common defect known as a nitrogen-vacancy center (NV center) has applications in both quantum information processing and ultra-sensitive magnetometry, the measurement of exceedingly faint magnetic fields. In an experiment, recently published in Science, JQI Fellow Vladimir Manucharyan and colleagues at Harvard University used NV ...

Sharper Nanoscopy

A new study from Edo Waks' group has shown how to sharpen nanoscale microscopy (nanoscopy) even more by better locating the exact position of the light source. The improvement involves taking into account the phantom dipole induced in the surface of a nanowire by the presence of a nearby quantum dot. The interference of light emitted by the dot with light emitted (in effect) by the phantom distorts the estimation of the dot's true location.

Modular Entanglement Using Atomic Ion Qubits

JQI researchers, under the direction of Christopher Monroe have demonstrated modular entanglement between two atomic systems, separated by one meter. Here, photons are the long distance information carriers entangling multiple qubit modules. Inside of a single module, quantized collective vibrations called phonons connect individual qubits. In the latest result, one module contains ...

Novel Phases for Bose Gases

Strongly correlated electronic systems, like superconductors, display remarkable electronic and magnetic properties, and are of considerable research interest. These systems are fermionic, meaning they are composed of a class of particle called a fermion. Bosonic systems, composed another family of particles called bosons, offer a level of control often not possible in solid ...
