Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

One of the most important experiments of quantum physics gets a makeover: When neutrons are fired at a crystal, they can be made to travel along two paths at the same time. Until now, this was only ...

Interferometers are research instruments that are utilized in many disciplines of science and technology. Interferometers are so-called because they function by combining multiple sources of light to ...

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, ...

Extremely precise measurements are possible using atom interferometers that employ the wave character of atoms for this purpose. They can thus be used, for example, to measure the gravitational field ...

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with ...

It may sound like an oxymoron, but this massive nanoparticle made up of 7,000 sodium atoms is the largest to exhibit such quantum behavior.

Vibrations can produce a number of significant challenges when conducting phase-shifting laser interferometer measurements. Today’s advanced interferometers have the capacity to measure with nanometer ...
