Title: Electric field control for experiments with atoms in Rydberg states
Authors: Aishik Panja, Yupeng Wang, Xinghan Wang, Junjie Wang, Sarthak Subhankar, Qi-Yu Liang,
Abstract summary: Atoms in Rydberg states have large polarizabilities, making them highly sensitive to electric fields. It is therefore essential to cancel these stray electric fields. We present a novel, simple, and highly-compact electrode assembly, implemented in a glass cell-based vacuum chamber design, for stray electric field cancellation.

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.

Impact of micromotion on the excitation of Rydberg states of ions in a Paul trap [0.0]
We develop a model describing a single trapped Rydberg ion, which we solve numerically via Floquet theory and analytically using a perturbative approach. We analyze in which parameter regimes addressable and energetically isolated Rydberg lines persist, which are an important requirement for conducting coherent manipulations.

We propose a scheme for engineering the potential in a Paul trap to realize a two-level quantum system with a giant EDM formed by the motional states of a trapped electron. We show that, under realistic experimental conditions, the EDM can significantly exceed the ones attainable with Rydberg atoms.

Quantum control of nuclear spin qubits in a rapidly rotating diamond [62.997667081978825]
Nuclear spins in certain solids couple weakly to their environment, making them attractive candidates for quantum information processing and inertial sensing. We demonstrate optical nuclear spin polarization and rapid quantum control of nuclear spins in a diamond physically rotating at $1,$kHz, faster than the nuclear spin coherence time. Our work liberates a previously inaccessible degree of freedom of the NV nuclear spin, unlocking new approaches to quantum control and rotation sensing.

We study the motion-induced radiation due to the non-relativistic motion of an atom in the presence of a static graphene plate. We show that the effect of the plate is to increase the probability of emission when the atom is near the plate and oscillates along a direction perpendicular to it.

Both molecular electronic and nuclear spin levels can be used as qubits. In solid state systems with dopants, an electric field was shown to effectively change the spacing between the nuclear spin qubit levels. This hyperfine Stark effect may be useful for applications of molecular nuclear spins for quantum computing.

Electrical control of spins at the nanoscale offers architectural advantages in spintronics. Recent demonstrations of electric-field (E-field) sensitivities in molecular spin materials are tantalising. E-field sensitivities reported so far are rather weak, prompting the question of how to design molecules with stronger spin-electric couplings.
