Neues KI-Konzept weist Weg zu Quantenrobotern The Austrian newspaper Der Standard reports on a recent article in "Nature Scientific Reports" about using quantum effects in the simulation of artificial intelligence (in German).	Experiment nimmt auf Vergangenheit Einfluss The Austrian newspaper Der Standard brings an article about an experiment that influences the past (in German).	Verschränkte Photonenpaare in Halbleiter-Chip realisiert The Austrian newspaper Der Standard brings a story about entangled photon pairs in semi-conductor chips (in german).
Wir brauchen nicht 14, sondern 100.000 Quantenbits The Austrian newspaper Der Standard brings an interview with Ignacio Cirac (in german).	Quantum Information Toolkit Quantum Information Toolkit (QIT) is a free, open source numerical toolkit for various quantum information and computing -related purposes, distributed under GPL. It is available for both MATLAB (version 7.6 or newer) and Python 2.6.	QuCoSi QuCoSi is a C++ library for simulating a quantum computer. Its name is an acronym for Quantum Computer Simulation. QuCoSi allows to build elemental to complex quantum circuits easily using its Qubit and Gate classes. The used qubits and gates are plain column vectors and unitary matrices that can be inspected and modified easily. Its emphasis lies on readability and ease of use instead of speed or optimization.
Bewegliche Spiegel zur Theorie-Einschränkung The Austrian newpaper Der Standard writes about a new propose experiment to test Planck-scale physics with quantum optics (in german).	IBM rückt Realisierung von Quantencomputern entscheidend näher The Austrian newspaper Der Standard reports an IBM press release (in German).	Trivial Low Energy States for Commuting Hamiltonians, and the Quantum PCP Conjecture We consider whether or not Hamiltonians which are sums of commuting projectors have "trivial" ground states which can be constructed by a local quantum circuit of bounded depth and range acting on a product state. While the toric code only has nontrivial ground states, commuting projector Hamiltonians which are sums of two-body interactions have trivial ground states.

Analytic and numerical demonstration of quantum self-correction in the 3D Cubic Code A big open question in the quantum information theory concerns feasibility of a self-correcting quantum memory. A quantum state recorded in such memory can be stored reliably for a macroscopic time without need for active error correction if the memory is put in contact with a cold enough thermal bath. In this paper we derive a rigorous lower bound on the memory time $T_{mem}$ of the 3D Cubic Code model which was recently conjectured to have a self-correcting behavior.
