Quantum measurement | Quantum information science
A quantum clock is a type of atomic clock with laser cooled single ions confined together in an electromagnetic ion trap. Developed in 2010 by physicists as the U.S. National Institute of Standards and Technology, the clock was 37 times more precise than the then-existing international standard. The quantum logic clock is based on an aluminium spectroscopy ion with a logic atom. Both the aluminum-based quantum clock and the mercury-based optical atomic clock track time by the ion vibration at an optical frequency using a UV laser, that is 100,000 times higher than the microwave frequencies used in NIST-F1 and other similar time standards around the world. Quantum clocks like this are able to be far more precise than microwave standards. (Wikipedia).

Time Is of the Essence… or Is It?
What is time? Isaac Newton described it as absolute, but Einstein proved that time is relative, and, shockingly, that time and space are intricately interwoven. Now recent work in string theory and quantum gravity suggests that space and time may not be fundamental. If this is true, what n

Andreas Albrecht - What is Time?
Time is a mystery; it's not what it seems. Time's flow feels unstoppable, yet some say time is not fundamental, perhaps not even real. Why do physicists and philosophers think time is a construct, something that emerges, not something that is basic? For more on information and video inter
