If left to run for some 14 billion years — roughly the current age of the universe — a new type of atomic clock could keep accurate time to within a tenth of a second.

The design by US experts makes use of a bizarre phenomenon called quantum entanglements, in which particles become inextricably linked.

This entanglement, the researchers explained, helps reduce the uncertainty involved in measuring the oscillation of atoms used by atomic clocks to keep time.

The clock could be used to help reveal the elusive ‘dark matter’ thought to make up more than three-quarters of the universe — and to study gravity’s effect on time.

If left to run for some 14 billion years — roughly the current age of the universe — a new type of atomic clock could keep accurate time to within a tenth of a second.  Pictured, the new design works by measuring the oscillation of ytterbium…
