Cascaded Optomechanical Sensing for Small Signals
Marta Maria Marchese, Daniel Braun, Stefan Nimmrichter +1
We propose a sensing scheme for detecting weak forces that achieves Heisenberg-limited sensitivity without relying on entanglement or other non-classical resources. Our scheme util…
Quantum Metrology of Spin Sensing with Free Space Electrons
Santiago Beltrán-Romero, Michael Gaida, Philipp Haslinger +2
Recent advances in transmission electron microscopy (TEM) have opened the path toward spin resonance spectroscopy with single-spin sensitivity. To assess this potential, we investi…
Electron-Enabled Nanoparticle Diffraction
Stefan Nimmrichter, Dennis Rätzel, Isobel C. Bicket +2
We propose a scheme for generating high-mass quantum superposition states of an optically pre-cooled, levitated nanoparticle through electron diffraction at its sub-nanometer cryst…
Metrology of Gravitational Effects with Mechanical Quantum Systems
Daniel Braun, Marta Maria Marchese, Stefan Nimmrichter +3
Mechanical quantum systems, such as resonators and levitated particles, offer unique opportunities for quantum metrology. Particularly, their significant mass and quantum-level con…
