- Abstract: Dipole-dipole interactions lead to frequency shifts that are expected to
limit the performance of next-generation atomic clocks. In this work, we
compute dipolar frequency shifts accounting for the intrinsic atomic multilevel
structure in standard Ramsey spectroscopy. When interrogating the transitions
featuring the smallest Clebsch-Gordan coefficients, we find that a simplified
two-level treatment becomes inappropriate, even in the presence of large Zeeman
shifts. For these cases, we show a net suppression of dipolar frequency shifts
and the emergence of dominant non-classical effects for experimentally relevant
parameters. Our findings are pertinent to current generations of optical
lattice and optical tweezer clocks, opening a way to further increase their
current accuracy, and thus their potential to probe fundamental and many-body
physics.

The rotational dynamics of a direct-current atomtronic quantum interference device is studied.
A parity protection scheme survives within a small interval around the central frequency.
It is found that such a maximum admissible error in the frequency determination turns out to be inversely proportional to the qubit quality factor.

The ratchet effect is achieved in the quantum control model with dissipation and sink, where the Hamiltonian depends on vibrations in the energy difference synchronized with transitions between energy levels.
Amplitude and frequency of the oscillating vibron together with the dephasing rate are the parameters of the quantum ratchet which determine its efficiency.

Temporal, spectral, and sample-to-sample fluctuations in coherence properties of qubits form an outstanding challenge for the development of upscaled fault-tolerant quantum computers.
A ubiquitous source for these fluctuations in superconducting qubits is a set of atomic-scale defects with a two-level structure.
We show that frequency modulation of a qubit or, alternatively, of the two-level defects, leads to averaging of the qubit relaxation rate over a wide interval of frequencies.
