Quantiki

The purpose of the meeting is to gather experts and young researchers working in the field of cold atoms at the interface with solid state physics in order to explore the state of the art and discuss the most fruitful perspectives.

There is no registration fee to attend the meeting but interested participants are required to notify the organiser by sending an e-mail to: samanta.piano@nottingham.ac.uk.

Understanding physics from the point of view of information led to the emergence of many new fields over the last years. These fields correspond to different approaches to the notion of information, from the perspective of mathematics, computer science, and philosophy. This workshop aims to represent all of these and their interaction with quantum physics. It is organized jointly by the quantum information group of LTCI, Telecom ParisTech, and CEA-LARSIM.

We'd like to announce the next Q+ hangout and hope to see you there!

As usual, we will reserve space in the hangout itself for those watching as a group. Comment below to reserve a seat. The talk will be livestreamed for everyone else.

Title: Exponential decay of correlations implies area law

The meeting aims to bring together researchers on the foundations of quantum theory from across all the institutions in London to facilitate collaboration and training of early career researchers. Details are as follows:

There is no fee to attend this meeting, but registration is required so that we know how many people to cater for, since we will be providing lunch and refreshments during the day. To register, please send an email to

Quantum information is the science of using quantum mechanics in a variety of ways to explore new ways of computing and handling information. At the end of the day, us, the scientists, have to find ways to implement non-classical gates and memory into the real world. Materials, allowing for quantum superpositions, single emitters in the solid state and other new-born materials in the nano-world have to pave our way to build the quantum computer. These quantum materials need to be investigated and project the physicist on the track to quantum computing suddenly to a material scientist.

The purpose of our workshop is to present and discuss recent developments in the overlap area between quantum information and foundations of quantum mechanics. The workshop is centered around, but not limited to, the following topics:
* Quantum logic beyond Birkhoff and von Neumann
* Contextuality and non-locality of quantum mechanics
* Measurement-based quantum computation
* Quantum mechanics and category theory
* QM foundations and cryptography

Contributed talks and posters are invited. Registration and submission will open in February 2013.

Decoherence is a bridge between quantum and classical and an Achilles’ heel of quantum computation. For the past 30 years Wojciech Zurek led development of the theory of decoherence and studied its implications for the foundations of quantum physics and its consequences for quantum information science and technology. We will invite his collaborators as well as prominent contributors to the field to celebrate Wojciech’s 60th birthday and his 30 years of decoherence studies.

The search for a theory which would unite the insights of general relativity with those of quantum theory, a theory of quantum gravity, has now lasted the better part of a century. Although a number of promising candidate theories have emerged (string theory and loop quantum gravity being the most prominent), a large array of conceptual, formal and methodological issues are still unresolved.
