Our lab is recognized in the UCSB The Current article, "Chip-scale cold atom and trapped ion experiments can unleash the power of quantum science in the field". The article highlights our recent accomplishments and what's to come from our lab in the near future.

An excerpt from the article reads, "Cold atom experiments are among the most powerful and precise ways of investigating and measuring the Universe and exploring the quantum world. By trapping atoms and exploiting their quantum properties, scientists can discover new states of matter, sense even the faintest of signals, take ultra-precise measurements of time and gravity, and conduct quantum sensing and computing experiments.

However, as powerful and sophisticated these experiments are, currently they’re still confined to the highly controlled environment of the laboratory, set up on optical tables and racks of equipment designed to isolate the environment and afford users the stability to precisely align the various lasers and optical components — including lenses, modulators, frequency shifters and other components that generate, manipulate and tune light waves needed for quantum experiments.

There’s a wealth of knowledge to be gained by taking these experiments out of the laboratory and using their power to measure and monitor phenomena in the outside world, according to UC Santa Barbara electrical and computer engineering professor Daniel Blumenthal.

“You can measure sea level rise, changes in sea ice, even earthquakes with a hundred-kilometer precision,” he said. “Literally, events happening on Earth you can see from the gravitational fields around the planet. Additionally, precise measurements of time in space will open up new avenues of gravitational experiments and search for new particles such as dark matter.” "
