A number of many-body problems can be formulated using Hamiltonians that are quadratic in the creation and annihilation operators. Here, we show how such quadratic Hamiltonians can be efficiently estimated indirectly, employing very few resources. We find that almost all properties of the Hamiltonian are determined by its surface, and that these properties can be measured even if the system can only be initialised to a mixed state.

Quantum Africa is a new series of conferences planned to take place consecutively in several African countries. The start of the series will be hosted in Durban by the Centre for Quantum Technology with a conference on progress in quantum technologies. Just as a successful preceding conference, it will feature many international renowned speakers and experts in quantum information processing, quantum optics, ultra-cold atoms and other relevant areas of quantum technologies. We hope to welcome many guests from Africa as well as from overseas.

We offer a three-day introductory course on quantum information and ultracold quantum gases, addressed to advanced undergraduate students before or just starting with a master or diploma thesis. Specialized knowledge in the field is not required, just basic knowledge in quantum physics and AMO physics.

Building on the quantumCity initiative, the eThekwini Municipality and the Centre for Quantum Technology, a research group of the University of KwaZulu-Natal (UKZN), has moved to secure the network linking the Moses Mabhida Stadium and the Joint Operation Centre in the city of Durban during the 2010 FIFA World Cup.

At the atom chip lab in Ben-Gurion university in Israel we do a wide range of work from fundamental theory, through experiments and ending with material engineering for quantum optics. Candidates for post-doc positions in any of the above categories are welcome to apply. The BGU university is very close to the red sea, the mediterranean sea and the dead sea. We are in the midst of an exotic region filled with archaeology thousands of years old, fascinating geology and breathtaking nature.
