Second 'Quantum Logic Clock' Based on Aluminum Ion Is Now World's ...
NIST postdoctoral researcher James Chin-wen Chou with the world's most precise clock, based on the vibrations of a single aluminum ion (electrically charged.
Science Centric | News | NIST's second 'quantum logic clock' based ...
Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminium atom that is now the world's most precise clock, more than twice as ...
Quantum Logic Clock 100000 Times More Accurate than Standard ...
The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time to within a second every 3.7 billion years. The new timekeeper could one day improve GPS or detect the slowing of time predicted by Einstein's ...
Second 'Quantum Logic Clock' Based on Aluminum Ion twice as ...
We have constructed an optical clock with a fractional frequency inaccuracy of 8.6 × 10^−18, based on quantum logic spectroscopy of an Al+ ion. A simultaneously trapped Mg+ ion serves to sympathetically laser-cool the Al+ ion and ...
Recently, scientists have built a clock that is more precise than any existing international clock. The clock is 37 times more precise and is called the quantum atomic logic clock. A physicist named Chin-Wen Chou is building the clock. ...
Second 'Quantum Logic Clock' Based on Aluminum Ion Is Now World's ...
The new clock is the second version of NIST's "quantum logic clock," so called because it borrows the logical processing used for atoms storing data in experimental quantum computing, another major focus of the same NIST research group. ...
2Physics: World's Most Precise Clock : NIST Developed Second ...
The new aluminum clock would neither gain nor lose one second in about 3.7 billion years, according to measurements reported in Physical Review Letters. The new clock is the second version of NIST's “quantum logic clock”, ...
Quite A Series Of Remarkable Things Happen In Quantum Theory
It means that the universe has a global clock. Before the redefiner takes a step the current status of the universe is governed by static laws such as quantum logic and the Helmholtz decomposition theorem. After taking the step these ...
Quantum-logic clock loses a second in 3.7 billion years
The use of UV lasers on aluminum and magnesium ions instead of aluminum and beryllium, to see very thin vibrations, is what makes this quantum-logic clock twice or even more precise than any other such clock ever perceived. ...
Quantum logic measurement. The local-oscillator laser is then fired at the aluminium ion and the efficiency at which the ion absorbs the light is determined by a technique called quantum logic spectroscopy (QLS). QLS is possible ...
