And yes, they aim to make it smaller in size for smartphone dead reckoning. The mysterious phenomenon of 'spooky action at a distance,' which once troubled Einstein, could soon become as commonplace as the gyroscopes used to measure acceleration in smartphones. A recent study in Nature Photonics
Quantum entanglement is a phenomenon in quantum mechanics where two or more particles can become correlated in such a way that the state of one particle is dependent on the state of the other particle, even when separated by great distances. This means that a change in the state of one particle can instantaneously affect the state of the other particle, regardless of the distance between them.
Usually in interferometry systems, the further the light travels, the more accurate the system becomes. The most sensitive interferometry system on the planet, the Laser Interferometer Gravitational-Wave Observatory, sends light on 8-kilometer journeys. But that’s not going to fit in a smartphone.in miniaturized optomechanical sensors, Zhang’s team explored quantum entanglement.
In squeezed light, the photons are more closely related to one another. Zhang contrasted what happens when the photons go through a beam splitter with cars coming to a fork in the freeway.
