Shuo Sun wins Maiman Outstanding Student Paper Competition

JQI graduate student Shuo Sun has won the Maiman Outstanding Student Paper Competition at CLEO, held annually in May. Sun's paper was titled "A solid-state spin-photon transistor." According to the website, "This competition was established in 2008 in memory of Theodore Maiman and in acknowledgement of his amazing invention, the first working laser, and his other outstanding contributions to optics and photonics.

Magic Wavelengths

Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information.  These outsized atoms can be sustained for a long time in a quantum superposition condition---a good thing for creating qubits---and they can interact strongly with other such atoms, making them useful for devising the kind of logic gates needed ...

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 ...

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.
