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…
