Progress in quantum computing with neutral atom qubits has advanced rapidly with the development of large 2D arrays and high fidelity entangling gates. We have used an array of Cs atom qubits to demonstrate a variational simulation of the Lipkin-Meshkov-Glick model incorporating noise mitigation techniques. In further work we have used a small error detecting code to implement a prototype...
The propagation of optical waves is traditionally understood as two distinct processes: beam (spatial) and pulse (temporal) propagation. However, spatiotemporal three-dimensional (3D) wave packets—featuring unique combinations of spatial and temporal wave characteristics—open the door to novel phenomena. In this seminar, we will explore the progress made in understanding these 3D optical wave...
Ionizing radiation has been shown to reduce the performance of superconducting quantum circuits. In this talk, I will first provide an overview of this rapidly evolving area of research, up to the implications of the latest demonstration of quantum error correction gains by Google. I will provide an overview of some of our recent work that identifies potentially problematic sources of...
Our group at the University of Colorado Boulder (CU Boulder) and the National Institute of Standards and Technology (NIST) has over a decade of experience in developing quantum calorimeters based on the superconducting transition-edge sensor (TES). More recently, we have began exploring the calorimetric capabilities of the kinetic inductance detector (KID), a superconducting resonator...
