QIA takes the stage at #MWC25! 🚀

This week we are at the Mobile World Congress in Barcelona, as part of the @QuantumFlagship booth!

We're hosting a series of talks with QIA partners @ICFOnians, Q*BIRD, Welinq showcasing quantum internet innovations.

Stay tuned for more!💫

Back in 2022 we taught single photon detectors how to skateboard. Now it is our entangled photon source's turn to hop on a quantum ride!

All we want for Christmas is... more Thorlabs lab snacks! 🎄🔴 Built this festive masterpiece out of Thorlabs boxes—now all that's missing is 20 t-shirts for our lab crew. @Thorlabs, can you help us out? #ThorlabsChristmas #LabLife #SnackTree

1/7: Exciting progress in quantum memories! We have demonstrated high-efficiency storage and retrieval of photonic qubits using a cavity-enhanced solid-state quantum memory. Let's dive into the details! @ICFOnians #QuantumPhysics #Photonics

[QPSA @QuantumPSA]

6/7: Using the AFC protocol, we achieved 51% efficiency for storing weak coherent time-bin qubits with a fidelity larger than 95 %, only limited by the qubits preparation. This method leverages the crystal’s inhomogeneous broadening for temporal multiplexing. #Quantum
