Researchers analyze how quantum vacuum fluctuations can drive macroscopic switching in a biased degenerate optical parametric oscillator, and how an external bias field can reshape the system’s bistable landscape. The work offers a clearer picture of noise-assisted dynamics relevant to photonic computing and probabilistic quantum hardware.

A new differentiable design study shows how a phase-induced amplitude apodisation Zernike wavefront sensor can capture more starlight and improve sensitivity for extreme adaptive optics, especially in photon-starved and partially resolved-star conditions.
