"One thing exciting about this experiment is that right now, there are not a lot of people doing these sorts of things鈥攃ombining cryogenics with optical tweezers," says Ting-Wei Hsu, a graduate student working with Cindy Regal (Physics, JILA) at Q-SEnSE, an NSF Quantum Leap Institute led by CU Boulder.

In collaboration with JILA and NIST Fellow James Thompson, Jun Ye's team generated quantum entanglement using spin squeezing, resulting in an enhancement in atomic clock performance operating at the 10-17 stability level. Their novel experimental setup was recently published in Nature Physics.

CU Boulder has announced seven winners of the 2023-2024 translational quantum research seed grants, incentivizing quantum science and technology innovations launched from the lab to accelerate them along the development path to new programs and businesses.

In quantum computer chips, information can quickly jumble up, like the cream in your morning coffee. However, Rahul Nandkishore (Physics) and his team have demonstrated that scientists can create a scenario where the milk and coffee never mix, potentially expanding the memory capabilities of quantum chips.

After simulating superconductivity in an excited state using an atom-cavity system, research teams at JILA have observed three distinct phases of superconducting dynamics, including a rare 鈥淧hase III鈥� featuring persistent oscillatory behavior predicted by condensed matter physics theorists but never before observed.

In a new Optica paper, Jun Ye (Physics, JILA) and his team, working with JILA electronic staff member Ivan Ryger and Hall, implemented a new approach for the Pound-Drever-Hall (PDH) method, reducing RAM to never-before-seen minimal levels while making the system more robust and simpler.

Senator Hickenlooper was given a brief tour of JILA, meeting with several instrument makers to see equipment purchased with congressionally directed spending. The senator then engaged in a comprehensive roundtable discussion with Colorado leaders in the quantum computing industry and academic sectors.

Four major foundations have launched a collaborative funding effort totaling $30 million for 11 pioneering "tabletop" experiments. One of the awarded experiments, led by JILA and NIST Fellow Jun Ye and his research team, involves the development of ultra-precise atomic clocks.

"A physicist's goal is to answer a core scientific question that we don鈥檛 have an answer to," says Rieker. "And an engineer鈥檚 goal is to solve a problem for which we don鈥檛 have a solution. Q-SEnSE ... [brings] those two states of mind together, helping us bridge technology in a way that I don't think has been possible before."

While many physicists focus on qubits found in nature, such as atoms and ions, JILA Associate Fellow and CU Boulder Professor Shuo Sun (Physics) is taking a different approach by studying 鈥渁rtificial atoms,鈥� or semiconducting nanocrystals with unique electronic properties.
