Efficient Conversion of Optical to Mechanical States Close to the Single-Quantum Level
Alexander Rolf Korsch, Liu Chen, Pedro V. Pinho +5
Coherent interfaces between optical photons and mechanical excitations provide a promising route towards phonon-state engineering and hybrid quantum information processing. Cavity…
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…
Step-by-step design guide of a cryogenic three-axis vector magnet
Gaia Da Prato, Yong Yu, Ronald Bode +1
A tunable magnetic field at low temperatures is essential for numerous applications, including spintronics, magnetic resonance imaging, and condensed matter physics. While commerci…
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…
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…
Microwave-optics entanglement via coupled opto- and magnomechanical microspheres
Hao-Tian Li, Zhi-Yuan Fan, Huai-Bing Zhu +2
Microwave-optics entanglement plays a crucial role in building hybrid quantum networks with quantum nodes working in the microwave and optical frequency bands. However, there are l…
