Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

A research team led by Professor Cheol Song at the Department of Robotics and Mechatronics Engineering, Daegu Gyeongbuk Institute of Science and Technology (DGIST), has successfully developed an ...

Melbourne, Australia: It's not the size of the interferometer that matters; it's how you use it. So claim a team of researchers from RMIT University, the University of Sydney and University of ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

An illustration of the Berkeley group’s lattice interferometer, where the standing wave of a laser beam in a cavity suspends each atom in a spatially separated quantum superposition state, in the ...

A few years ago researchers using the radio-based Event Horizon Telescope (EHT) performed an extraordinary observation, the likes of which remains a dream for most other astronomers. The EHT team ...
