The Quantum Information Science & Technology group at Stony Brook University focuses on novel quantum memories and processors that will enable future quantum information networks and computing.
In particular, we develop scalable quantum memories for photonic polarization qubits based on electromagnetically induced transparency (EIT) in warm Rubidium vapor. We also develop cavity-enhanced entanglement sources tuned to atomic transitions that are compatible with our memories.
In collaboration with Brookhaven National Laboratory, we are using our testbed, LIQuIDNET, to develop a Quantum-enabled network. Ensuring precise timing and polarization stability between our two campuses.
Additionally, we design quantum transistors and logic gates using electromagnetically induced transparency and cold atoms inside optical cavities.
