- Abstract: In this paper we propose a dark-state-based trapping strategy to break the
optical diffraction limit for microscopy. We utilize a spatially dependent
coupling field and a probe laser field with temporal and spatial modulation to
interact with three-level atoms. The temporal modulation allows us to reduce
the full width at half maximum (FWHM) of point spread function, and the spatial
modulation help us obtain better spatial resolution than Gaussian beam. In
addition, we also propose a proof-of-principle experiment protocol and discuss
its feasibility.

Entanglement between atoms, generated by the exchange of virtual photons through a common cavity mode, grows exponentially fast.
We propose to exploit this for quantum-enhanced sensing of an optical phase (common and differential between two ensembles)
Our proposal can open unique opportunities for the observation of continuous variable entanglement in atomic systems and associated applications in next-generation optical atomic clocks.

Scheme operates with laser and cavity fields detuned from the atomic transition by much more than the excited-state hyperfine splitting.
This enables reduction of the dynamics to that of a simple, cavity-damped Tavis-Cummings model with the collective spin determined by the total angular momentum of the ground hyperfine level.

spatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information.
Current approaches for dynamically generating and measuring these modes are slow, due to the need to reconfigure a high-resolution phase mask.
We experimentally realize this approach, using a double-pass AOM to generate one of five orbital angular momentum states.
We are able to reconstruct arbitrary states in under 1 ms with an average fidelity of 96.9%.

Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.
Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes.
We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
