Daniel Brod soon to join the UFF group as faculty

We have just got the good news that my former PhD student Daniel Jost Brod will soon join the Infoptics group at UFF as faculty. After his PhD, Daniel spend 2 1/2 years a post-doc at Perimeter Institute, and had since last March been back at UFF as a postdoc. Daniel’s research focuses on restricted models of quantum computation, linear and non-linear optics, and foundational issues. He’s a friend and long-time collaborator of mine, I’m very happy with the outcome, it’s a great addition to the quantum information community in Rio.

Congratulations Daniel, welcome aboard, Professor!

Here’s a picture of the first, improvised celebration yesterday, when the concurso’s result was announced.

Talk @UFF, Carlos Eduardo R. de Souza, Friday Oct. 27th, 11:00

This week’s group seminar at UFF will be given by Carlos Eduardo Rodrigues de Souza (IF-UFF), who’ll be talking on “Simetrias em feixes gêmeos com momento angular orbital
produzidos em um oscilador paramétrico óptico”. All are welcome to attend! The talk is next Friday, October 27th, at 11:00 in room A5-01. Please check the abstract below.
Data: Sexta-Feira 27/10/2017, Sala A5-01, 11 am.

Palestrante: Carlos Eduardo Rodrigues de Souza (UFF)

Título: Simetrias em feixes gêmeos com momento angular orbital
produzidos em um oscilador paramétrico óptico

Abstract: O Oscilador Paramétrico Óptico (OPO) é uma fonte lasers gêmeos
intensos com correlações quânticas com potenciais aplicações nas áreas
de Computação e Informação Quântica. Esse dispositivo foi construído
aqui no Laboratório de Óptica Quântica do IF-UFF, onde são realizados
experimentos de medida de ruído quântico e estudos da dinâmica do
momento angular da luz na produção de feixes gêmeos.

Neste seminário serão descritos os princípios básicos do funcionamento
do OPO. Também serão apresentados os resultados preliminares
referentes a um estudo experimental da dinâmica de um OPO injetado com
uma superposição coerente de vórtices ópticos de primeira ordem, os
modos de Laguerre-Gauss. Veremos que a dinâmica dos feixes gêmeos
produzidos no experimento, interpretada através da representação
geométrica de Poincaré, apresenta uma simetria marcante. Pretendo dar
um caráter básico e informal nesta apresentação, de forma que os
estudantes e as estudantes serão especialmente super bem-vindos(as)
para discutirmos tanto as especificidades dos resultados quanto a
física envolvida.

Título: Power of Adiabatic Quantum Computing: Theory and Reality

Resumo:
The paradigm of Adiabatic Quantum Computing (AQC) is a simple yet intriguing approach to problem solving on a quantum computer. Unlike the more recognized quantum circuit model, AQC is an analog method that does not require the use of quantum gates and is therefore considered by many easier to implement. I will discuss recent theoretical developments in the field of AQC as well as our current understanding  of the power and limitations of experimental quantum adiabatic processors.
