Abstract
Atoms excited to Rydberg states have recently emerged as a valuable resource
in neutral atom platforms for quantum computation, quantum simulation, and
quantum information processing. Atoms in Rydberg states have large
polarizabilities, making them highly sensitive to electric fields. Therefore,
stray electric fields can decohere these atoms, in addition to compromising the
fidelity of engineered interactions between them. It is therefore essential to
cancel these stray electric fields. Here we present a novel, simple, and
highly-compact electrode assembly, implemented in a glass cell-based vacuum
chamber design, for stray electric field cancellation. The electrode assembly
allows for full 3D control of the electric field in the vicinity of the atoms
while blocking almost no optical access. We experimentally demonstrate the
cancellation of stray electric fields to better than 10 mV/cm using this
electrode assembly.
