Graduate Student Matt Norcia (Thompson group) received a JILA Scientific Achievement Award on February 18. The announcement took place during a special snack time in the Sunrise Room of the JILA Tower.

Norcia was cited for building a strontium cavity-QED experiment from scratch. Norcia’s advisor, James Thompson, nominated him for the prestigious award. Thompson noted that Norcia’s...

Kevin Cox received an Outstanding Presentation Award at the July 15, 2015, NIST Boulder Laboratories Postdoctoral Poster Symposium. Cox was recognized for his presentation “17 dB of Spin Squeezing with QND Measurements.” Cox is a graduate student in the James Thompson group at JILA. He co-authored the poster with Graham Greve, Joshua Weiner, and Thompson.

The award citation read, “The...

Dynamical phase transitions in the quantum world are wildly noisy and chaotic. They don’t look anything like the phase transitions we observe in our everyday world. In Colorado, we see phase transitions caused by temperature changes all the time: snow banks melting in the spring, water boiling on the stove, slick spots on the sidewalk after the first freeze. Quantum phase transitions happen,...

The spooky quantum property of entanglement is set to become a powerful tool in precision measurement, thanks to researchers in the Thompson group. Entanglement means that the quantum states of something physical—two atoms, two hundred atoms, or two million atoms—interact and retain a connection, even over long distances.

Even without exploiting entanglement, atoms are already used...

James Thompson has been named the winner of a 2013 Department of Commerce Bronze Medal for his work on pioneering superradiant lasers. The superradiant laser is a quantum device that emits coherent lasing photons.

The DoC Bronze Medal is the highest honor the NIST Director can bestow upon NIST staff for outstanding accomplishments. The Bronze Medal citation reads “For pioneering the...

When the Thompson group first demonstrated its innovative “superradiant” laser the team noticed that sometimes the amount of light emitted by the laser would fluctuate up and down.  The researchers wondered what was causing these fluctuations. They were especially concerned that whatever it was could also be a problem in future lasers based on the same principles.

In the group’s...

Most scientists think it is really hard to correlate, or entangle, the quantum spin states of many particles in an ultracold gas of fermions. Fermions are particles like electrons (and some atoms and molecules) whose quantum spin states prevent them from occupying the same lowest-energy state and forming a Bose-Einstein condensate. Entanglement means that two or more particles interact and...

The Thompson group, with theory help from the Holland group, recently demonstrated a superradiant laser that escapes the “echo chamber” problem that limits the best lasers. To understand this problem, imagine an opera singer practicing in an echo chamber. The singer hears his own voice echo from the walls of the room. He constantly adjusts his pitch to match that of his echo from some time...

Physicists at JILA have demonstrated a novel "superradiant" laser design with the potential to be 100 to 1,000 times more stable than the best conventional visible lasers. This type of laser could boost the performance of the most advanced atomic clocks and related technologies, such as communications and navigation systems as well as space-based astronomical instruments.

The secret for reducing quantum noise in a precision measurement of spins in a collection of a million atoms is simple: Pre-measure the quantum noise, then subtract it out at the end of the precision measurement. The catch is not to do anything that detects and measures the spins of individual atoms in the ensemble. If states of individual atoms are measured, then those atoms stop being in a...

Alice couldn’t wait to get back to Quantumland. She’d spent the better part of the past week helping Mother host three teas and two garden parties in honor of her newly engaged sister Mary. Alice thought planning a wedding was pretty boring compared to scoping out a strange, cold world filled with odd creatures like talking atoms (the tiniest particles of matter).

At last, she was able...
