Today, the Quantum Optics Group has a well equipped Quantum Optics Laboratory capable of performing experiments based on twin photons generated in a nonlinear process. Furthermore, an optical tweezers experiment is devoted to study optical trapping at micro and at nano-scales. The Quantum Optics research lines concentrate both on theoretical as well as experimental problems. In particular, the group is studying problems in the area of Quantum information such as control of quantum systems via projective measurements, protocols for quantum communications via partially entangled states, quantum cryptography via non-orthogonal states and effective higher dimensional quantum systems. These research subjects deal with the possibility of understanding at a fundamental level quantum systems and controlling them to transmit, store and process information. The Quantum Optics Group has also conducted research on Quantum Optics in problems related to quantum decoherence and interference. We have been working on designing optimal reconstruction schemes for multi qubits system, which is a fundamental problem for any physically scalable quantum computer. We are currently implementing experiments for long distance quantum communications and fundamental tests of Quantum Theory based on Hardy’s approach.
