Congratulations Young Fellows!

The Brazilian Academy of Science (Academia Brasileira de Ciências) has just released the new members. One interesting class, created about 10 years ago, is the Affiliated Member (Membro Afiliado), which lasts for five years and focus on young promising scientists. In physics, São Paulo state has just elected five new Affiliated Members, three of them our SPN off QuBIT fellows Diogo de Oliveira Soares Pinto (USP), Gustavo Wiederhecker  (Unicamp), and  Thiago Pedro Mayer Alegre (Unicamp).

Congratulation, guys! Let us celebrate during our December Meeting.

Postdoctoral position in Quantum Information Science at the Centre for Quantum Technologies and Yale-NUS College, Singapore

A postdoctoral position in the field of Quantum Information Science is available at the Centre for Quantum Technologies (CQT), National University of Singapore, and Yale-NUS College (joint affiliation). The research focus is on theoretical studies of quantum error correction and fault tolerance, with a particular focus on applications in realistic quantum computing systems. This can include considerations for noise models relevant for current systems in the race for quantum computers, non-Markovian noise, thermodynamical analyses of noise removal procedures, etc.

The candidate should have a strong background in theoretical physics, possess numerical skills, and have an interest in understanding experimental work relevant to quantum computation. PhD work in quantum computing or quantum information related research is expected. Past experience with quantum error correction and fault tolerance, and/or the study of physical noise models will be a strong plus point.

The position commences in the first half of 2019 (negotiable), and is for two years. An extension into a third year may be possible depending on funding availability. The successful candidate will work in the group of Hui Khoon Ng, an Assistant Professor (Physics) at Yale-NUS College, and a CQT Fellow at the Centre for Quantum Technologies. The postdoc can expect many opportunities to work with graduate and undergraduate students within the group. Please refer to the group website for more information:

Interested applicants, please contact H. K. Ng directly at, with a statement of interest and a detailed curriculum vitae.

CQT ( is a National Research Centre of Excellence hosted at the National University of Singapore. The Centre comprises some 150 research staff and students, working in all areas of quantum information science. Yale-NUS College (http://www.yale-nus. is an undergraduate college, jointly founded by Yale University and the National University of Singapore, emphasizing a liberal arts and sciences education, with a commitment to building a strong research base at an early stage for science majors.

New Article in Jornal da USP

Our multitasking @gtlandi has now published an article in Jornal da USP, together with Luciana Schmidt, a Medical Doctor

It is in Portuguese, sorry for some readers, explaining some new contributions from the group of Eugene Polzik, at Niels Bohr Institute. They show how to optically measure magnetic fields with high sensitiveness and no need of cryogeny, and how this can be a viable alternative to electrocardiography (ECG), capable of noninvasive (in medical sense) monitoring of the heart of a fetus (this is the part that appeals to Luciana!).

Congratulations, Gabriel! Long life to the partnership with Luciana and with Jornal da USP.

BCG consulting firm report on business potential of quantum computing — quantum Rio

In a recent, freely available report, Boston Consulting Group (BCG), an American consulting firm, advises companies on the business potential of quantum computing over the next decade. To me, the report seems realistic and down-to-earth, avoids the all-too-common overhype, and doesn’t skip over relevant technical issues. There are also hard-to-find details on the amount of […]

Hi everyone,

I wanted to publicize a paper recently published in collaboration with Prof. Fernando Semião, from UFABC, together with researchers from Belfast, Cambridge, Viena and Zürich, on the experimental reconstruction of entropy production in mesoscopic quantum systems.

The paper was published in Physical Review Letters. It was chosen as editor suggestion and also appeared on the Synopsis section of the APS website.

In this paper we applied a formalism previously developed for estimating the entropy production (a quantifier of irreversibility) in quantum systems subject to non-equilibrium baths. Using this model, we were able to reconstruct the entropy production in a Bose-Einstein condensate (from Esslinger’s group in Zürich) and in an optomechanical cavity (from Aspelmeyer’s group in Viena).

Our results offer the first experimental demonstration of the contribution of quantum fluctuations in maintaining a non-equilibrium steady-state and, consequently, producing irreversible entropy.
