Data-driven synthesis of high-fidelity triaxial magnetic waveforms for quantum control
Giuseppe Bevilacqua, Valerio Biancalana, Roberto Cecchi
We present a system for generating arbitrary, triaxial magnetic waveforms with a spectral content spanning from DC to tens of kHz, a critical capability for quantum control and spi…
Multipassage Landau-Zener tunneling oscillations in transverse/longitudinal dual dressing of atomic qubits
Alessandro Fregosi, Carmela Marinelli, Carlo Gabbanini +7
We investigate the time evolution of a non-resonant dressed-atom qubit in an XZ original configuration. It is composed of two electromagnetic fields, one oscillating parallel and t…
Tri-axial time-dependent magnetic field calibrated in-situ by harmonic analysis of adiabatically evolving atomic spins
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
We introduce a methodology to calibrate in situ a set of coils generating bi- or tri-axial magnetic fields, at frequencies where a calibration performed under static conditions wou…
Studying and applying magnetic dressing with a Bell and Bloom magnetometer
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
The magnetic dressing phenomenon occurs when spins precessing in a static field (holding field) are subject to an additional, strong, alternating field. It is usually studied when…
A room-temperature alternating current susceptometer - Data analysis, calibration, and test
M. Alderighi, G. Bevilacqua, V. Biancalana +3
An AC susceptometer operating in the range of 10 Hz to 100 kHz and at room temperature is designed, built, calibrated and used to characterize the magnetic behaviour of coated magn…
Stray Magnetic Field Compensation with a Scalar Atomic Magnetometer
Jacopo Belfi, Giuseppe Bevilacqua, Valerio Biancalana +3
We describe a system for the compensation of time-dependent stray magnetic fields using a dual channel scalar magnetometer based on non-linear Faraday rotation in synchronously opt…
All-optical magnetometry for NMR detection in a micro-Tesla field and unshielded environment
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
An all-optical atomic magnetometer is used to detect a proton free-precession signal from a water sample polarized in a 0.7 T field and remotely analyzed in a 4 field. Nuclear…
All optical sensor for automated magnetometry based on Coherent Population Trapping
J. Belfi, G. Bevilacqua, V. Biancalana +2
An automated magnetometer suitable for long lasting measurement under stable and controllable experimental conditions has been implemented. The device is based on Coherent Populati…
