Full professor at the Institute of PHysics at the University of São Paulo. PHD by the Institute of Physics at the University of São Paulo (2002), I had visited the Laboratoire Kastler Brossel at Université Paris-7 (2001, 2010) and the University of Toronto (2003). Hired at the University of São Paulo in 2004. I work on Quantum Optics and Atomic Physics applied to Quantum Information, studying the generation and the use of entangled states of light from optical parametric oscillators and atoms.

Studies in quantum information using discrete or continuous variables of the electromagnetic field imply in the productions and control of quantum states of light, as well as the storage of these states in matter, eventually allowing the process of information using the principles of quantum mechanics. The final goal is achieving superior information processing capacity, solving problems …
Parametric amplification is a powerful tool for the generation of entangled and squeezed states of the electromagnetic field. A revival of the interest for these states came on the last decade thanks to their potential applications in quantum information, with the use of cluster states for information processing.On the other hand, high levels of squeezing are on the verge of their applica…
In quantum optics, the measurements involving quadratures of the field generally use the beat signal involving the central carrier of the field and the noise contained in the two sidebands. This characteristic feature of the detection implies a limitation to the direct application of entanglement tests proposed in the theory, involving covariances among single field modes. We plan to inve…

States involving multiple modes that are entangled in the continuous variable domain have applications in metrology and quantum information processing. The current project suggests the use of parametric amplification, generated from a four wave mixing process in atomic vapor, as a source of networks of entangled states. Four wave mixing process in vapor cells proved to be a robust source …
Our group is performing new measurements of quantum correlations in silicon nitride microcavities, using a C-band laser as a pump for in-chip parametric oscillators. These systems have great potential in the versatile generation of entangled states. Their applications goes from sensitive metrology in multicolor systems to the generation of multiple entangled states in a scalable system, w…
The proposed research project aims at the evaluation of possible experiments using the techniques of quantum optics on the Sirius Synchrotron facility. We will study the distinct beamlines, both installed and under commission, considering their application. For instance, in one commissioned beamline the orbital angular momentum of the radiation can be controlled, what opens relevant possi…

We are looking for the generation of entangled states for applications in quantum information processing. The goal is generation of a scalable structure of entangled modes. This entanglement allows the sharing of information in a secure way by quantum cryptography protocols between the players (Alice and Bob), and allows the development of systems for information processing that should ov…
The final goal of the associated project is the generation of entangled states for applications in quantum information processing in a scalable structure of field modes. For this implementation, the development of optical amplifiers for applications in quantum information relies on the careful engineering of the parametric coupling. This can be done by tailoring the gain medium or the man…
With the recent achievement of classical state teleportation between fields of distinct colors, we aim at the next step, involving the transfer of quantum states between an atomic system and another system at the telecom L-band.We should use an Optical Parametric Oscillator built with a PPKTP crystal, pumped by a 532 nm laser. It will produce an entangled pair in 795 and 1608 nm. In order…

Each improvement in the sensitivity of gravitational wave detectors allows for the observation of even more distant events. This corresponds to an increase in the frequency with which they are detected, allowing researchers to study and investigate phenomena that were not previously accessible using regular telescopes. For this reason, gravitational wave observatories constantly undergo i…
