Moving trapped-ion qubits in a microstructured array of radiofrequency traps offers a route
toward realizing scalable quantum processing nodes. Establishing such nodes, providing …

Present protocols of criticality-enhanced sensing with open quantum sensors assume direct
measurement of the sensor and omit the radiation quanta emitted to the environment …

Fabry–Perot interferometers have stimulated numerous scientific and technical applications
ranging from high-resolution spectroscopy over metrology, optical filters, to interfaces of light …

Continuous monitoring of driven-dissipative quantum-optical systems is a crucial element in
the implementation of quantum metrology, providing essential strategies for achieving highly …

Multiparticle entangled quantum states, a key resource in quantum-enhanced metrology and
computing, are usually generated by coherent operations exclusively. However, unusual …

Recently, integrated photonic circuits have brought new capabilities to electron microscopy

We study the frequency splitting of the polarization eigenmodes of the fundamental
transverse mode in CO 2 laser-machined, high-finesse optical Fabry–Perot cavities and …

Optical microresonators confine light to a particular microscale trajectory, are exquisitely
sensitive to their microenvironment, and offer convenient readout of their optical properties …

We observe a sixfold Purcell broadening of the D 2 line of an optically trapped Rb 87 atom
strongly coupled to a fiber cavity. Under external illumination by a near-resonant laser, up to …
