The magnetic sensing at nanoscale level is a promising and interesting research topic of
nanoscience. Indeed, magnetic imaging is a powerful tool for probing biological, chemical …

Several high-precision physics experiments are approaching a level of sensitivity at which
the intrinsic quantum nature of the experimental apparatus is the dominant source of …

We describe an ultrasensitive atomic magnetometer based on optically pumped potassium
atoms operating in a spin-exchange relaxation free regime. We demonstrate magnetic field …

Superconducting quantum interference devices (SQUIDs) can be used to detect weak
magnetic fields and have traditionally been the most sensitive magnetometers available …

We report the levitation of a superconducting lead-tin sphere with 100 μ m diameter
(corresponding to a mass of 5.6 μ g) in a static magnetic trap formed by two coils in an anti …

We observe measurement-induced qubit state mixing in a transmon qubit dispersively
coupled to a planar readout cavity. Our results indicate that dephasing noise at the qubit …

The science of superconducting electronics was first developed over forty years ago, fifty
years after the discovery of superconductivity. Since then, a wide range of applications has …

The energy resolution per bandwidth ER is a figure of merit that combines the field
resolution, bandwidth or duration of the measurement, and size of the sensed region …

Electron-beam lithography and reactive ion etching have been used to fabricate thin-film
Au/Nb bridges with widths 50nm. The Au layer was used as both a mask for etching the Nb …

Different approaches have improved the sensitivity of either electron or nuclear magnetic
resonance to the single spin level. For optical detection it has essentially become routine to …
