Low-noise Optomechanical Single Phonon-photon Conversion for Quantum Networks
Liu Chen, Alexander Rolf Korsch, Cauê Moreno Kersul +4
Nano-structured optomechanical crystals (OMC) form an interface between mechanical modes with long coherence times and telecom optical photons, ideal for long-distance distribution…

A cryogenic chamber setup for superfluid helium experiments with optical fiber and electrical access
Alexander R. Korsch, Niccolò Fiaschi, Simon Gröblacher
Superfluid helium is a prototypical quantum liquid. As such, it has been a prominent platform for the study of quantum many body physics. More recently, the outstanding mechanical…

Time-resolved spectral diffusion of a multimode mechanical memory
Niccolò Fiaschi, Lorenzo Scarpelli, Alexander Rolf Korsch +2
High-frequency phonons hold great promise as carriers of quantum information on-chip and as quantum memories. Due to their coherent interaction with several systems, their compact…
