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 @ICFOnians

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
