Coupling free electrons to a trapped-ion quantum computer

Elias Pescoller, Santiago Beltrán-Romero, Sebastian Egginger +10

Freely propagating electrons may serve as quantum probes that can become coherently correlated with other quantum systems, offering access to advanced metrological resources. We pr…

When Higher Resolution Reduces Precision: Quantum Limits of Off-Axis Interferometric Scattering Microscopy

Felix Hitzelhammer, Jonathan Dong, Ulrich Hohenester +1

Coherent interferometric scattering microscopy (iscat) enables nanoparticle tracking on microsecond timescales and with nanometer precision, and has become a key tool in structural…
