JILA Fellow Cindy Regal and her team, along with researchers at the National Institute of Standards and Technology (NIST), have for the first time demonstrated that they can trap single atoms using a novel miniaturized version of 鈥渙ptical tweezers鈥濃�攁 system that grabs atoms using a laser beam as chopsticks.

As the DoD's most prestigious research award, the Vannevar Bush Fellowship is oriented towards "bold and ambitious 鈥榖lue sky鈥� research that will lead to extraordinary outcomes." Fellows receive $3 million over a five-year fellowship term to pursue cutting-edge fundamental research projects.

鈥淚t鈥檚 amazing to see all these companies building off of Nobel Prize-winning research,鈥� said Philip Makotyn, executive director of the CUbit Quantum Initiative, which connects quantum researchers and companies in Colorado. 鈥淚t鈥檚 just a rich ecosystem that doesn't exist anywhere else.鈥�

Systems that cool qubits are difficult to scale up in size, posing a challenge for long-distance quantum communication systems. To bypass this issue, JILA Fellows Cindy Regal, Konrad Lehnert and their teams have created a transducer that uses side-banded cooling to convert microwave photons to optical photons.

Quantum technology promises sophisticated cybersecurity solutions that could shake up the future of computing. Companies are setting up shop in Colorado to develop quantum-security measures, with CU Boulder and federal research facilities partnering to boost the state's nascent quantum industry.

Qubits are a basic building block for quantum computers, but they鈥檙e also notoriously fragile鈥攖ricky to observe without erasing their information in the process. Now, new research from CU Boulder and NIST may be a leap forward for handling qubits with a light touch.

鈥淭his is a technology that was developed for something completely different鈥攆or creating better atomic clocks and other tools for quantum research,鈥� said Greg Rieker, an associate professor of mechanical engineering at CU Boulder. 鈥淣ow, we鈥檙e making an impact on climate change.鈥�

At the invitation of JILA and NIST Fellow Eric Cornell, who has been a scientist at the institute since the 1990s, CU President Todd Saliman toured several laboratories at JILA last month. Saliman was impressed by the research team and Fellows. 鈥淵ou are all working to change the world,鈥� he said.

In a new paper published in Physical Review X, JILA Fellow Adam Kaufman and his team have demonstrated that a specific isotope, mytterbium-171 (171Yb), can store quantum information in stable nuclear qubits鈥攚hich allows for the ability to quickly manipulate the qubits and produce them in large, uniformly filled arrays.

In a joint study, Jun Ye's and Ana Maria Rey's research groups established an experimental setting where they successfully observed Pauli blocking of spontaneous emission by direct measurements of an atom's excited state population. The results have been published in the journal Physical Review Letters.
