Periodic Reporting for period 1 - SQVAC (Quantum Simulator with Hot Atomic Vapors)
Période du rapport: 2024-05-01 au 2025-10-31
In the context of the ongoing development of novel quantum technologies, including
quantum sensors, quantum communication, quantum simulators and quantum computing,
some devices are mature without resorting to the powerful but fragile entanglement between qubits.
Exploiting the wave nature of devices, photons often play an important role. In order to enlarge the
potential of photonic devices, controlled atom-photon interactions will be pushed to new limits in order
to build analog and digital wave simulators. In the present project,
these interactions are mediated via photon-atom coupling using room temperature cells of atomic vapours.
Whereas Rydberg atoms are well idendified excited states, having allowed to implement efficient quantum many body studies when used with laser cooled and trapped samples, non linear effects based on ground and single excited states have attracted less attention. The goal of this project is to explore alternative approaches to exploit such lower lying excited states in room temperature samples and their potential for analog and digital 'quantum-inspired' simulations.

A novel experimental setup allowing to implement optical gates has been implemented.
Buffer gaz cells as well as paraffine coated cells have been tested and are in operation, ready to be used for linear and non linear optical processsing.

Initial tests have been performed to find route for non linear optical gates (e.g. CNOT gates) as well as for laser inscribed optical guiding.
