The microscopic description of 1/f magnetic flux noise in superconducting circuits has remained an open question for several decades despite extensive experimental and theoretical investigation. Recent progress devices quantum information highlighted the need to mitigate sources qubit decoherence, driving a renewed interest understanding underlying mechanism(s). Though consensus emerged attributing surface spins, their identity interaction mechanisms remain unclear, prompting further study....

Microwave photons inside lattices of coupled resonators and superconducting qubits can exhibit surprising matter-like behavior. Realizing such open-system quantum simulators presents an experimental challenge requires new tools measurement techniques. Here, we introduce Scanning Defect Microscopy as one tool illustrate its use in mapping the normal-mode structure microwave a 49-site Kagome lattice coplanar waveguide resonators. is accomplished by moving probe equipped with sapphire tip...
The majority of sources coherent optical radiation rely on laser oscillators driven by population inversion. Despite their technological importance in communications, medicine, industry, and other fields, it remains a challenge to access the spectral range 0.1--10 THz (the ``terahertz gap''), frequency band for applications ranging from spectroscopy security high-speed wireless communications. Here, we propose way produce spanning gap efficient second-harmonic generation low-loss dielectric...
We use a 2D array of injection-locked VCSELs to implement spatiotemporally multiplexed optical neural network and demonstrate image classification at high accuracy with GHz line rates.

We propose a coherent THz source by efficient, cascaded second harmonic generation from electronic oscillators. introduce hybrid dielectric cavity designs combining extreme field concentration in high-Q resonators with phonon-resonance-enhanced nonlinear materials.
