- Entanglement by four wave mixing in atomic media, AP.R
Abstract
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 appli...
- Exploring quantum information with atoms, crystals and chips, AP.TEM
Abstract
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 problem...
- Quantum information processing with continuous variables, AP.R
Abstract
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 in...
- Quantum information with continuous variables of atoms and light, AP.TEM
Abstract
Quantum Information Science attracts considerable attention owing to its fundamental character, on the one hand, since information is physical, meaning that physical systems are needed to store, process, and transmit it; and, on the other hand, to the potential technological applications. Since present-day computing is based on binary logic, it is natural to search for extensions in dis...
- Teleportation of quantum information between different colors, AP.R
Abstract
Since the assembling of the first Optical Parametric Oscillator in Brazil we have studied many aspects of this system that remained elusive, although they were predicted by the quantum theory and intensely studied by other research groups abroad. Afterwards, we demonstrated the entanglement of intense fields in the operation above threshold, predicted tripartite entanglement on the syst...

- Using atoms to manipulate cluster states, BP.PD
Abstract
Cluster states have been suggested as a quantum information resource for information processing. They may be used in quantum computation process and quantum process simulators/emulators. The challenge now it to generate and keep the entanglement in these systems along the information processing.We propose the use of cascaded optical parametric oscillators, pumped by multiple frequencies...
- Creating ladder states of light with hot vapor, BP.DR
Abstract
In the process of parametric amplification, entanglement comes naturally from the creation of photon pairs in two fields from the annihilation of one or more photons from the pump field. For the higher efficiency of this process, we may use an optically dense atomic vapor of atoms and use the high value of its third order susceptibility close to the atomic resonance.Our goal is the coup...
- Quantum teleportation using sideband modes: fundamentals of quantum optics and quantum information, BP.IC
Abstract
Information is stored, transmitted, and processed in physical systems. In recent years, quantum properties of physical systems have been investigated in order to improve the efficiency of information science protocols. In this project, we will investigate quantum teleportation in continuous variable systems, especially the possibility of boosting efficiency by using sideband modes of th...

- Producing entanglement between atoms and microcavities, BP.IC
Abstract
Entanglement is a fundamental resource in quantum manipulation of information. It is necessary for efficient information processing, overcoming tasks that are difficult for classical processors. It may also be used form implementation of quantum cryptography, and is necessary for teleportation of quantum states. Our proposal involves the generation of entanglement between fields of diff...
- Control of quantum information with continuous variables of light beams, BP.PD
Abstract
We aim at the generation of intense entangled light beams, with quantum correlations that are strong enough for successful implementation of teleportation in the continuous variables domain. Contrary to already existing systems, that rely on interferometry for entanglement generation, manipulation and measurement, we will use intense beams and self-homodyning techniques. They are necess...
- Quantum teleportation between light of different colors, BP.PD
Abstract
With the recent successful results obtained using optical parametric oscillators (OPOs) to generate intense entangledlight fields, we propose to use this entanglement in quantum communication protocols with continuous-variablesystems. At first, we will use two strongly correlated beams to teleport a coherent state between differentwavelengths of the electromagnetic spectrum. In order to...

- Experimental implementation of an atomic spin as a negative mass reference frame to overcome the standard quantum limit in gravitational-wave detectors, BE.EP.MS
Abstract
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...
