16.12.2025 by pricpr

$The study demonstrates that increasing detector temporal resolution-decreasing $\tau$ to $10^{-7}\mathrm{s}$ from $10^{-6}\mathrm{s}$- diminishes the total detection probability for Helium atoms due to the quantum Zeno effect, a phenomenon reflected in the narrowing of arrival-time distributions and a corresponding reduction in sampled points, despite maintaining consistent detector placement at $L_2 = 200\sigma_0$ and $L_1 = -20\sigma_0$.$

A new analysis explores the fundamental question of how to define and measure the arrival time of entangled particles, potentially impacting the future of quantum technologies.
