A method for achieving fully tunable entanglement between a single 40Ca+ ion and the polarization state of a single photon within an optical resonator is reported, providing a promising means of ...

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

Near the ion trap chip, two focused lasers propagating parallel to the trap surface produce 88 Sr + ions from the cold atomic beam by means of a two-step photo-ionization (PI) process, shown ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

For this purpose, this new ion crystal clock was compared with other optical clocks and a new accuracy record was achieved. The PTB researchers report their in Physical Review Letters. An undisturbed ...

An Ion milling system is a sample preparation apparatus that can section a surface very cleanly by applying an argon plasma ion beam to the sample. Because an ion mill removes material on an atomic ...

Last week, researchers at the Massachusetts Institute of Technology announced that they’d conducted a successful flight test of an aircraft with a sci-fi-sounding propulsion system called an ion ...

Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study. Atomic clocks are essential elements in GPS and other navigation systems ...
