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.

After reaching 26 years of contributions in quantum optics and atomic physics, our group has gathered resources and expertise to follow the efforts in these research areas in their applications in quantum information and extreme measurements. Our present proposal will therefore stretch over different subjects in the field. We will investigate the creation of quantum entangled networks in …
This proposal involves the fast investigation of the generation and the use of entangled states of light in quantum communication protocols. Our goal is the use of entanglement produced by an optical parametric oscillator as a resource for the teleportation of light states generated by atomic systems into the telecommunication L-band. At this wavelength, compatible with optical fibers, a …
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…
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 …

The capacity of transferring the information of a quantum state between two distinct sites without transporting the system itself defines the idea of teleportation, a resource that overcomes the limitation of reading and writing a quantum state, given by the no-cloning theorem. This process relies on the shared information of an entangled pair between two remote stations to perform the tr…
The development of new sources of quantum states of light have recently known a shift back into the use of nonlinearities in atomic vapors for entangled and squeezed state production. These results can be associated as a consequence of the strong nonlinearity in four wave mixing process either in hot atomic vapor or cold atoms.In the current proposal we will use the parametric amplifica…
We want to generate entangled states for applications in quantum information processing, in a system with modal scalability. Entanglement serves to two main goals: allowing the sharing of information in a safe way, by quantum cryptography between two players (Alice and Bob), and for the development of information processing in a way that will surpass the limits of the current classical co…

The complete information of a system can be given by its density operator. By performing a controlled evolution of the state, the lossless state transformation preserves the purity of this state. The preservation of the information, associated with the control over the purity, is a fundamental resource for the use of quantum mechanics as a resource for information processing, which may le…
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…

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…
