We demonstrate a memory for light based on optomechanically induced transparency. We achieve a long storage time by leveraging the ultralow dissipation of a soft-clamped mechanical membrane resonator, which oscillates at MHz frequencies. At room temperature, we demonstrate a lifetime ${T}_{1}\ensuremath{\approx}23\text{ }\text{ }\mathrm{ms}$ and a retrieval efficiency $\ensuremath{\eta}\ensuremath{\approx}40%$ for classical coherent pulses.

Such systems could find applications in emerging quantum networks, where they can serve as long-lived optical quantum memories by storing optical information in a phononic mode.We demonstrate a memory for light based on optomechanically induced transparency.

We demonstrate a memory for light based on optomechanically induced transparency. We achieve a long storage time by leveraging the ultra-low dissipation of a soft-clamped mechanical membrane resonator, which oscillates at MHz frequencies. At room temperature, we demonstrate a lifetime $T_1 \approx 23\,\mathrm{ms}$ and a retrieval efficiency $η\approx 40\%$ for classical coherent pulses. We anticipate storage of quantum light to be possible at moderate cryogenic conditions ( $T\approx 10\,\mathrm{K}$ ). Such systems could find applications in emerging quantum networks, where they can serve as long-lived optical quantum memories by storing optical information in a phononic mode.We demonstrate a memory for light based on optomechanically induced transparency.
