Paraty VI: Registration is open!

quantum Rio

The time has come… again. The sixth edition of the Quantum Information School and Workshop is accepting applications.

In this edition we will be celebrating 10 years from the first “Quantum Paraty”. Ten years have passed but the relaxed atmosphere — great science, long lunch breaks, friendly people, a boat trip instead of the boring usual conference dinner, and Paraty itself –, that build up the reputation of Paraty as the coolest quantum information conference in the world, continue as our commandment. Ask people about it and register! All the info and registration form can be found in the conference webpage

See you in Paraty!

Quantum Rio Workshop, Dec. 7/8th

quantum Rio

Next week, on December 7th and 8th, in CBPF (at the 6th floor auditorium), we’ll have our first Quantum Rio Workshop, an informal gathering of the quantum information community in and around Rio, organized by Malena Hor-Meyll (UFRJ), Roberto Sarthour (CBPF) and Ernesto Galvão (UFF).

The idea of the workshop is to foster more interaction and collaboration among the quantum information/quantum optics researchers in the area. We’ve allocated half-hour talk slots to some of the group leaders, complemented by posters and coffee during the talk breaks, mostly by students (please encourage them to contribute!). The workshop will be financed by workshop fees (paid only by professors).

Please find the schedule below:

Wednesday, Dec. 7th:
9:00-09:30 Luiz Davidovich
9:30-10:00 Fernando Melo
10:00-10:30 coffee
10:30-11:00 Gabriel Aguilar
11:00-11:30 Alexandre Souza
11:30-12:00 Ernesto Galvão
12:00-14:00 lunch
14:00-14:30 José Augusto Huguenin/Alexandre Schmidt
14:30-15:00 Mohammad Rajabpour
15:00-16:00 coffee/posters
16:30-17:00 Marcelo França
17:00-17:30 Leandro Aolita

BLOCO 2016

quantum Rio

———— Guest post by Jéssica O. de Almeida (UFRJ) e Gabriel D. Carvalho (CBPF) ————

Em outubro de 2016 acontecerá o BLOCO (Bienal Latinoamericana de Óptica Cuántica O), uma conferência satélite ao Quantum Optics. Essa conferência é voltada para os alunos da América Latina, dando oportunidade para que esses apresentem seus trabalhos. Professores também estão convidados, porém só poderão assistir as palestras e apresentar pôster. O evento será realizado no CBPF nos dias 19-21/10.

O BLOCO tem como objetivo dar oportunidade de alunos de pós-graduação e jovens pesquisadores latinos americanos exporem trabalhos na forma de seminários e pôsteres, além de trocar experiências científicas na América Latina. Isso fortalece os laços da comunidade de óptica quântica da América Latina, algo essencial para aumentar, ainda mais, a relevância internacional de nossos grupos.

As inscrições estão abertas! Veja mais informações e se inscreva no site

Minicourse @CBPF: Enrique Solano – 15-17.08, 10h30

quantum Rio

In August, Enrique Solano (University of the Basque Country) will be visiting the Quantum Information and Quantum Optics Group at UFRJ. Solano got his PhD in 2000 at UFRJ under supervision of Nicim Zagury. Today he is the head of the Quantum Technologies for Information Science at the University of the Basque Country, and has published around 30 papers just in 2016. Many of these papers are about quantum simulations.

During his visit, Solano will give a set of three lectures on “Fundamentals and applications of quantum simulations”. Due to the Olympic Games, the course will be held at CBPF. See the information below and don’t miss this chance! If you are planning to attend this course, and you should do it, please send an e-mail to fmelo [at], such that we can organize a corresponding lecture room and have a list of the participants at the entrance of…

Quantumness: A Celebration of Luiz Davidovich’s research career on his 70th birthday

quantum Rio

Dear quantum people,

next June, our dear colleague Luiz Davidovich will complete 70 years. To celebrate this event, we are organizing a conference to celebrate the scientific career Luiz entitled Quantumness, to be held on the campus of UFRJ from 22 to 24 June 2016.


At this conference, the multiple facets of Luiz’s scientific career will be represented, with seminars covering topics in Quantum Optics, Quantum Information and Atomic Physics. The line up of speakers is amazing!


You don’t want to miss that, do you? Even better, there is no registration fee!

Paraty Quantum Information School 2015 — lectures posted online!

quantum Rio

The 2015 edition of the Paraty Quantum Information School was the first time we filmed all the lectures! This was possible because this time the school was part of the “School for Advanced Studies”, a project from the Brazilian funding agency CAPES.

The videos are all online in our brand new YouTube channel. Subscribe!
Paraty Quantum Information School and Workshop channel

As it was the first time we did this… we have to improve it a lot. But in any case we hope that you can feel the relaxed atmosphere of the school and the high quality of its lecturers&lectures.

Stay tuned for the Paraty Quantum Information School 2017. See you there!

QM Talks@CBPF: Fernando Nicacio – 23.09, 16h00

Giving continuity to our series of seminars, this week we’ll have Fernando Nicacio, aka Boiuna, among us. Fernando was advised by Raul Vallejos (qig@CBPF), and at the moment he holds a postdoc position at UFABC, working on quantum thermodynamics. Boiuna is a very charismatic person who can discuss quantum mechanics as easily and passionately as he can discuss the lyrics of the next Carnival “samba enredos” — two major issues here in Rio.

The details of his talk are below. If you are interested in good physics delivered in a good mood way, be sure not to miss Fernando Nicacio’s talk!
See you there.

Speaker: Fernando Nicacio (UFABC)

Title: Effective Dynamics of Harmonic Networks in a Thermal Environment

Coordinates: room 601D, CBPF. 23.09, 16h00

Abstract: In this seminar, we will perform a thoroughly study of the dynamics of an arbitrary network of coupled harmonic oscillators aiming at the establishment of trustful simpler effective Hamiltonians and Liouvillians. We consider the weakening a few coupling constants in the network, as put forward for the linear chain configuration in [1], and grow over it by expanding the idea to general topologies and by including thermal baths. We show that, in this general scenario, it is still possible to attain an effective dynamics involving just a few quantum systems and, at the same time, keeping a high accuracy in the description of the physical properties of the harmonic network. In order to illustrate the predictability of the reduced dynamics, we present a comparative predictions between exact and effective descriptions in the context of propagation of energy and correlations through the network.
