Optical atomic clocks with eighteen significant digits are the most accurate measurement devices avail
Fermionic quantum simulators provide a powerful platform for exploring high-temperature superconductivity, topological phases, and many-body dynamics—challenges that persist even with the advent of qubit-based quantum computing. In this talk, I will present recent results from our high-repetition-rate fermionic quantum gas microscope, which is optimized for rapid data acquisition. Fast cycle times on the order of a few seconds are achieved through high-power optical traps, rapid evaporative cooling, and efficient spin-resolved fluorescence imaging.
Long-lived optical clock states of alkaline earth and alkaline earth-like atoms have many applicati
Abstract: Black holes are often portrayed as cosmic vacuum cleaners that swallow everything, even light. In reality, they are far richer and more revealing: each black hole is a natural laboratory where the two great pillars of modern physics — Einstein’s general relativity and quantum mechanics — meet head-on. In this talk, we will venture from the known, the black holes that we can observe in our sky, into the unknown, where we begin to understand how black holes obey the rules of quantum mechanics.
Abstract: The upcoming Libera mission, NASA’s first Earth Venture Continuity selection, will provide seamless continuity to current broadband radiance measurements obtained by the Clouds and Earth’s Radiant Energy System (CERES) project since March 2000.
Ultracold polar molecules possess inherent strong electric dipole moments and a rich internal structure, making them ideal platforms for implementing novel quantum information schemes, performing precision quantum metrology, and exploring exotic quantum phases such as dipolar BEC-BCS crossover in molecular Fermi gases. However, such experiments require extensive control over two or more species of atoms and their interactions, significantly scaling up the complexity and construction period of the experiment setup.
The JILA Association of Graduate Students (JAGS) is excited to announce the next session of the JILA Graduate Student Seminar Series! Please join us next Thursday, June 5th, at 12:30 in the JILA Auditorium, with the talks beginning at 12:45.
The talks for this session are:
Student voice in quantum education - Kristin Oliver, Lewandowski PER Group
Engineering Collective Decoherence-Free Subspaces - Lyryl Vaecairn, Holland Group
Please come by and explore the research going on at JILA! There will also be lunch provided.
In this talk, Shinho Kim will discuss photonic systems studied across distinct spectral regimes, from the visible to the mid-infrared. His work addresses multiscale and multiphysics challenges in light–matter interactions, with each spectral regime involving fundamentally different mechanisms and applications.
Neutral-atom arrays with single-particle detection and control are a powerful tool for quantum science. In this defense, I present results from two projects, both performed with the same tweezer-programmable neutral-strontium-array apparatus. First, we engineer Rydberg interactions to create entangled spin-squeezed states, whose measurement noise can outperform classical limits. In a synchronous optical-frequency comparison between two spin-squeezed ensembles of atoms, we realize a measurement with a stability better than the standard quantum limit.
Abstract forthcoming
Nonequilibrium quantum systems exhibit phenomena not seen in equilibrium but are also less well understood. To study these systems, quantum simulators hold much promise due to their broad tunability and access to measurement observables. In this defense, I present experiments engineering nonequilibrium quantum phases of matter using many strontium atoms in a high-finesse optical cavity. Observations include a first experimental realization of three dynamical phases in quenched BCS superconductors and insights into many-body gap protection in fermionic superfluids.

Title: Bounded-Error Quantum Simulation via Hamiltonian and Liouvillian Learning
Dear JILAns,
With everything happening in the world, building a strong scientific community seems more important than ever. Posterfest is a chance to come together, celebrate JILA’s research, and support each other’s work.
We hope you’ll join us for JILA Posterfest 2025, happening at 3 pm on Thursday, May 1, in the X-Wing.
Abstract:
Gauge theories are ubiquitous in fundamental physics with applications ranging from high-energy particle physics over emergent phenomena in condensed matter to quantum information science and technology. Since several regimes of interest have remained inaccessible to classical simulations, they constitute an ideal target for quantum simulations.
