The Quantum Leap in Measuring Earth’s Rotation: A New Frontier in Physics
In the realm of scientific discovery, breakthroughs often arise at the intersection of theoretical concepts and technological advancements. A recent study has demonstrated how quantum entanglement—one of the most enigmatic phenomena in physics—can be harnessed to measure the rotation of the Earth using an optical interferometer. This revolutionary approach not only expands our understanding of quantum mechanics but also paves the way for advancements in precision measurement technology.

Quantum Mechanics and Interferometry: Understanding the Basics
Interferometers have long been a cornerstone in experimental physics, serving as precision instruments for measuring distances, gravitational waves, and even fundamental constants of nature. The optical Sagnac interferometer, developed in the early 20th century, is one of the most sensitive devices for detecting rotational motion. This instrument operates on the principle that light traveling in opposite directions along a rotating loop will experience different travel times due to the Earth’s rotation.
Traditionally, these interferometers have been bound by the limitations of classical physics. However, by introducing quantum entanglement, researchers have enhanced their sensitivity beyond classical constraints. Quantum entanglement occurs when two or more particles become linked in such a way that the state of one instantly influences the state of the other, regardless of distance. This property allows scientists to extract more information from each measurement, surpassing the precision limits imposed by classical physics.
Observing Earth’s Rotation with Quantum Entanglement
A team of researchers from the University of Vienna, led by physicist Philip Walther, has demonstrated an unprecedented method of measuring Earth’s rotation by using entangled photons in a Sagnac interferometer. Their study, titled “Experimental Observation of Earth’s Rotation with Quantum Entanglement,” marks a significant milestone in quantum metrology.
To conduct this experiment, the researchers created a large optical fiber Sagnac interferometer, spanning 2 kilometers (1.2 miles) of coiled fiber optic cable. When pairs of entangled photons traveled in opposite directions within this loop, they exhibited super-resolution behavior, effectively amplifying the rotational signal. This unique characteristic enabled the team to achieve a level of sensitivity 1,000 times greater than that of early quantum optical interferometers.
One of the major challenges in this study was isolating the Earth’s rotational signal from environmental noise. Since stopping the planet’s rotation is impossible, the team devised an innovative solution: they split the optical fiber into two coils of equal length and used an optical switch to toggle between them. By alternately enabling and disabling the rotation signal, they ensured the reliability and stability of their measurements over extended periods.
