A resource theory for Maxwell’s demon’s

Hi everyone,

I’m here to publicize our latest paper, which was accepted on Quantum, on a resource theory for Maxwell’s demon’s:


We show that the set of resourceful states can be partitioned into 9 irreducible subsets, each with well defined (although not monotonic) temperatures. This, as we discuss, has dramatic consequences for Landauer’s principle.

Hope you enjoy!
All the best,

Gabriel Landi

Paraty 2019 – Time to register!

We would like to announce the “VII Paraty Quantum Information School and Workshop” (http://2019.paratyquantum.info/) that will take place in Paraty, Brazil from August 05 to 16, 2019.

We would be grateful if you could spread the word and bring the event to the attention of your group and to anyone else that might be interested. A pdf poster can be found in this link.

As in previous editions, the idea is to merge high level scientific exchange and a very pleasant atmosphere. The event will be held at the idyllic setting of Paraty, on Rio de Janeiro’s Costa Verde. The school runs from 5 to 9 August while the workshop takes place between 12 and 16 August 2019. Come and be part of this story!

Courses of the school:

Quantum-assisted machine learning in near-term quantum devices
Alejandro Perdomo-Ortiz (University College London)

Entangled Structures in Classical and Quantum Optics
Antonio Zelaquett Khoury (Fluminense Federal University)

Characterising quantum correlation via semi-definite programming

Quantum computing over the rainbow: continuous-variable quantum information in the optical frequency comb
Olivier Pfister (University of Virginia)

High-dimensional Quantum Information
Yelena Guryanova (IQOQI-Vienna)

Open Quantum System Dynamics
Sabrina Maniscalco (Turku University)

Application deadline is April 21st for the school and May 12th for the workshop.


We look forward to seeing you there!

Emergent platforms for quantum information processing – 15-17/04 @ IFUSP

Hi everyone,

We would like to advertise the workshop Emergent platforms for quantum information processing, that will take place at IFUSP-São Paulo between April 15-17 of 2019. The focus of the workshop will be on experimentalists from Brazil working in quantum information processing platforms. Our goal is that this workshop serve as an opportunity for getting together and discussing the advantages, limitations and prospects. We hope, with this, to call attention to the community in Brazil to the importance of experimental quantum information sciences.

The event’s official website is: http://www.fmt.if.usp.br/~platform/

The conference program will be available soon.

Organizers: Gabriel T. Landi (IFUSP), Luis Gregório Dias (IFUSP), Frederico Borges Brito (IFSC).

PhD @ University of Düsseldorf, with Gláucia Murta!

Gláucia Murta is moving to Düsseldorf, this summer, and will possibly be my first daughter to bring grandchildren to my academic family.
Below you can see her advertising message. Candidates?
Best wishes to Gláucia, to Düsseldorf, and to whoever joins her in this adventure!
Dear friends,
In June I will be joining Dagmar Bruss’ group at Heinrich Heine University Düsseldorf.
In light of that, I’m currently looking for a PhD student who is motivated to work on quantum theory of network communication, with projects in the interface of quantum information theory, coding theory, quantum foundations and cryptography.
More information and details on how to apply can be found here:
I would be grateful if you could spread the word among prospective candidates.

PhD and PostDoc with Ana Belén Sainz, @ Gdansk

Call for a PhD student position and a postdoctoral position at the International Centre for Theory of quantum Technologies (ICTQT), University of Gdansk, Poland.
We are offering a four-year PhD studentship and a three-year postdoctoral position to motivated and qualified students and researchers in the fields of quantum foundations and quantum information.
The ideal starting date is Oct. 1, 2019 for the PhD call, and Sep. 1, 2019 for he postdoctoral call, but it may be negotiable.
The researchers will work at the Foundational Underpinnings of Quantum Technologies group lead by Ana Belén Sainz, on mathematical and conceptual foundations of quantum mechanics, quantum computation and quantum information.
The deadline for applications is March 31, 2019.
Applications may me submitted online at:
