Information, Dissipation, and Planckian Optimality

Kavli Affiliate: Debanjan Chowdhury | Summary:We derive a universal bound on the efficiency with which "dissipated" work can generate distinguishable changes in a quantum many-body state at a finite temperature, as quantified by the quantum Fisher information. The bound follows solely from the analytic structure of equilibrium many-body correlators and is independent of all microscopic […]

Requirements for Teleportation in an Intercity Quantum Network

Kavli Affiliate: Stephanie Wehner | Summary:We investigate the hardware requirements for quantum teleportation in an intercity-scale network topology consisting of two metropolitan-scale networks connected via a long-distance backbone link. Specifically, we identify the minimal improvements required beyond the state-of-the-art to achieve an end-to-end expected teleportation fidelity of $2/3$, which represents the classical limit. To this […]

EPISODE III: The Nested Jet/Outflow Morphology of EC 53 Revealed by JWST and ALMA

Kavli Affiliate: Gregory Herczeg | Summary:We present an extensive study of the structure and kinematics of the jet and outflow of EC 53, a Class I protostar with a quasi-periodic variability, using combined James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA) observations. ALMA continuum observations resolve a compact disk with a radius […]

Entanglement improves coordination in distributed systems

Kavli Affiliate: Stephanie Wehner | Summary:Coordination in distributed systems is often hampered by communication latency, which degrades performance. Quantum entanglement offers fundamentally stronger correlations than classically achievable without communication. Crucially, these correlations manifest instantaneously upon measurement, irrespective of the physical distance separating the systems. We investigate the application of shared entanglement to a dual-work optimization […]

A high rate of foreground contaminants toward high-redshift galaxies resolved by JWST

Kavli Affiliate: Linhua Jiang | Summary:We present a study of high-redshift Ly$α$ emitters (LAEs) with multiple components using HST and JWST. High-redshift galaxies are mostly point-like objects on ground-based images, but they often exhibit multiple components in higher spatial resolution images. JWST for the first time allow detailed analyses on these individual components. We collect […]
