We use the vibrational levels of hydrogen molecules as a memory for light to store 100-fs pulses. We also demonstrate non-classical correlations in an emissive quantum memory using rotational levels of hydrogen molecules.

We demonstrate a memory for light based on storing photons in the vibrations of hydrogen molecules. The THz-bandwidth memory is used to store 100-fs pulses for durations up to ~ 1ns, enabling ~ 104 operational time bins.

The unusual features of quantum mechanics are enabling the development of technologies not possible with classical physics. These devices utilize nonclassical phenomena in the states of atoms, ions, and solid-state media as the basis for many prototypes. Here we investigate molecular states as a distinct alternative. We demonstrate a memory for light based on storing photons in the vibrations of hydrogen molecules. The THz-bandwidth molecular memory is used to store 100-fs pulses for durations up to ~1 ns, enabling ~10(4) operational time bins. The results demonstrate the promise of molecules for constructing compact ultrafast quantum photonic technologies.
