Introduces superconducting Talbot effect: a macroscopic quantum self-imaging phenomenon enabling direct measurement of Fermi wavelengths in 2D electron gases via phase-controlled Josephson junctions without external magnetic fields.
Researchers achieved nearly 30 dB of quantum-limited gain across ~1 GHz bandwidth by cascading two SNAIL-based traveling-wave parametric amplifiers, combining ultra-low noise and high gain for quantum information processing.
