Ultrafast timing enables reconstruction-free positron emission imaging

Nature Photonics, Published online: 14 October 2021; doi:10.1038/s41566-021-00871-2Positron emission imaging without tomographic reconstruction is demonstrated. A Cherenkov radiation detector detects gamma rays produced by positron–electron annihilation. The position of a positron source is determined with a precision of 4.8 mm.

Optomechanical quantum teleportation

Nature Photonics, Published online: 07 October 2021; doi:10.1038/s41566-021-00866-zQuantum teleportation of a photonic qubit into mechanical modes of two silicon photonic crystal nanobeams is demonstrated. It allows to store and retrieve an arbitrary qubit state onto a dual-rail encoded long-lived optomechanical quantum memory.
