Precision laser spectroscopy of cold and trapped molecular ions is a powerful tool in fundamental physics—used, for example, in determining fundamental constants, testing for their possible variation in the laboratory, and searching for a possible electric dipole moment of the electron. However, the absence of cycling transitions in molecules poses a challenge for direct laser cooling of the ions, and for controlling and detecting...

Non-destructive state detection for quantum logic spectroscopy of molecular ions
Precision laser spectroscopy of cold and trapped molecular ions is a powerful tool in fundamental physics—used, for example, in determining fundamental constants, testing for their possible variation in the laboratory, and searching for a possible electric dipole moment of the electron.

Quantum physics: Entanglement beyond identical ions
Control of quantum particles has been extended to enable different types of ion to be entangled — correlated in a non-classical way. This opens up opportunities for the development of new quantum technologies. See Letters p.380 & p.384

CERN’s Large Hadron Collider hits 1-PeV milestone with heavy ions (and re-ignites doomsday talk)
The Large Hadron Collider set another record for particle-smashing energy levels this week – which set off another round of hyped-up rumblings about the end of the world. Before the LHC’s startup in 2008, the Internet was set abuzz with worries that high-energy collisions could create globe-gobbling black holes or cosmos-wrecking strangelets. Protests were mounted, lawsuits were...
