A Hiroshima University team has designed a feasible way to detect the Unruh effect, where acceleration turns quantum vacuum fluctuations into observable particles. By using superconducting Josephson junctions, they can achieve extreme accelerations that create a detectable Unruh temperature. This produces measurable voltage jumps, providing a clear signal of the effect. The breakthrough could transform both fundamental physics and quantum technology.
The work was recently published in Physical Review Letters.
The Fulling-Davies-Unruh effect, or simply the Unruh effect, is a striking theoretical prediction at the profound intersection of Albert Einstein’s Theory of Relativity and Quantum Theory. “… [4828 chars]
