Demonstration of suppressed phonon tunneling losses in phononic bandgap shielded membrane resonators for high-Q optomechanics
Yeghishe Tsaturyan, Andreas Barg, Anders Simonsen +4
Dielectric membranes with exceptional mechanical and optical properties present one of the most promising platforms in quantum opto-mechanics. The performance of stressed silicon n…
Heater self-calibration technique for shape prediction of fiber tapers
Heidi L. Sørensen, Eugene S. Polzik, Jürgen Appel
In the production of tapered optical fibers, it is important to control the fiber shape according to application-dependent requirements and to ensure adiabatic tapers. Especially i…
Quantum interference of a single spin excitation with a macroscopic atomic ensemble
S. L. Christensen, J. -B. Béguin, E. Bookjans +4
We report on the observation of quantum interference of a collective single spin excitation with a spin ensemble of atoms. Detection of a single photon scat…
Optical detection of radio waves through a nanomechanical transducer
T. Bagci, A. Simonsen, S. Schmid +8
Low-loss transmission and sensitive recovery of weak radio-frequency (rf) and microwave signals is an ubiquitous technological challenge, crucial in fields as diverse as radio astr…
Graphene on silicon nitride for optoelectromechanical micromembrane resonators
Silvan Schmid, Tolga Bagci, Emil Zeuthen +12
Due to their exceptional mechanical and optical properties, dielectric silicon nitride (SiN) micromembrane resonators have become the centerpiece of many optomechanical experiments…
Quantum Teleportation of Dynamics and Effective Interactions Between Remote Systems
Christine A. Muschik, Klemens Hammerer, Eugene S. Polzik +1
Most protocols for Quantum Information Processing consist of a series of quantum gates, which are applied sequentially. In contrast, interactions, for example between matter and fi…
