But if you want the ultimate in accuracy, you’ll want a quantum atomic interferometer. What that is, and how it will be possible to make one small enough to be useful, is half of the story.

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies ...

But if you want the ultimate in accuracy, you’ll want a quantum atomic interferometer. What that is, and how it will be possible to make one small enough to be useful, is half of the story.

Quantum sensor technology based on matter-wave interferometry explores new methods for the development of inertial sensors for enabling high-precision measurements of rotations and accelerations with ...

Quantum optics is making impressive advances ... If all the photons are injected into one input port of the interferometer, we can describe their evolution individually, following Dirac's remark ...

W hat will it take to detect dark matter—the invisible, nigh-intangible substance that might make up five-sixths of all ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion.

The most accurate clocks to date rely on atomic transitions in the optical regime. On the other hand, some of the best inertial sensors employ atom interferometers, which exploit the wave nature of ...

They can detect extremely weak magnetic fields, making them valuable tools for applications such as brain imaging, geophysical surveys, and quantum computing. Atomic interferometers use the ...

Review of quantum fields; quantization of the electromagnetic field; photodetection theory; direct, homodyne and heterodyne detection; squeezed and photon-number state generation; application to ...

the quantum efficiency a(v0 ... It follows that the fundamental principle of the interferometer represented in Fig. 16 is sound, and it is proposed to examine in further detail its application ...

12, 2024 — For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the ...
