- Abstract summary: We outline a new physical mechanism to map the state of photons onto the long-lived but optically inaccessible collective state of noble-gas spins.
The mapping employs the coherent spin-exchange interaction arising from random collisions with alkali vapor.
We identify feasible experimental conditions for realizing efficient quantum memories with noble-gas spins having hours-long coherence times at room temperature and above.

- Abstract: Optical quantum memories, which store and preserve the quantum state of
photons, rely on a coherent mapping of the photonic state onto matter states
that are optically accessible. Here we outline a new physical mechanism to map
the state of photons onto the long-lived but optically inaccessible collective
state of noble-gas spins. The mapping employs the coherent spin-exchange
interaction arising from random collisions with alkali vapor. We analyze
optimal strategies for high-efficiency storage and retrieval of non-classical
light at various parameter regimes. Based on these strategies, we identify
feasible experimental conditions for realizing efficient quantum memories with
noble-gas spins having hours-long coherence times at room temperature and above

We consider an ensemble of Alkali atoms that are continuously optically pumped and probed.
Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state.
We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

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.
