Researchers at the University of Vienna led by Philip Walther just pioneered the field of quantum mechanics and general relativity by measuring “the effect of the rotation of Earth on quantum entangled photons,” as stated in a press release.
In the Vienna experiment, they used an interferometer, which is the most sensitive to rotations. Their unparalleled precision makes them the ultimate tool for measuring rotational speeds, limited only by the boundaries of classical physics.
Interferometers employing quantum entanglement have the potential to break those bounds. If two or more particles are entangled, only the overall state is known, while the state of the individual particle remains undetermined until measurement.
