In the fractional quantum Hall effect, electrons in a strong magnetic field organize into collective states. Such states behave as quasiparticles, known as anyons, that carry a fraction of the ...

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 ...

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, ...

A research team of RIKEN center for Advanced Photonics and the University of Tokyo has developed a novel type of interferometer to resolve the fringes originating from both optical interference of ...

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 ...

White light interferometry is increasingly being adopted for thin film measurement and high‑precision distance applications ...

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 ...

A team of researchers from France has developed the first three-directional hybrid quantum inertial sensor, which can measure acceleration without using satellite signals. At the heart of this ...
