Although today's best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known as quantum projection ...
New frontiers in the study of the universe—and gravitational waves—have been opened up following a breakthrough by University of the West of Scotland (UWS) researchers.
The thorium isotope with the mass number 229 (229Th) is highly exciting in many respects—for fundamental physics as well as for future applications, for example in the sense of a nuclear clock.
Darmstadt physicists have developed a technique that could overcome one of the biggest hurdles in building a practically-relevant quantum computer. They make use of an optical effect here discovered by British photo pioneer ...
China sent three astronauts to its Tiangong space station on Tuesday, putting a civilian into orbit for the first time as it pursues plans to send a crewed mission to the Moon by 2030.
China successfully launched the latest mission to its Tiangong space station on Tuesday, with a crew that includes its first civilian astronaut.
Atomic clocks are the world's most precise timekeepers. Based on periodic transitions between two electronic states of an atom, they can track the passage of time with a precision as high as one part in a quintillion, meaning ...
Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...
In recent years, many physicists worldwide have introduced atomic clocks, systems to measure the passing of time that are based on quantum states of atoms. These clocks can have numerous valuable applications, for instance ...
Researchers at the National Institute of Standards and Technology (NIST) have developed chip-scale devices for simultaneously manipulating the color, focus, direction of travel, and polarization of multiple beams of laser ...
