Hybrid magic state distillation for universal fault-tolerant quantum computation
Wenqiang Zheng, Yafei Yu, Jian Pan +7
A set of stabilizer operations augmented by some special initial states known as 'magic states', gives the possibility of universal fault-tolerant quantum computation. However, mag…
Experimental observation of a phase transition in the evolution of many-body systems with dipolar interactions
Gonzalo A. Alvarez, Dieter Suter, Robin Kaiser
Non-equilibrium dynamics of many-body systems is important in many branches of science, such as condensed matter, quantum chemistry, and ultracold atoms. Here we report the experim…
Transferring entangled states through spin chains by boundary-state multiplets
Peter Lorenz, Joachim Stolze
Quantum spin chains may be used to transfer quantum states between elements of a quantum information processing device. A scheme discovered recently \cite{BFR+12} was shown to have…
Experimental implementation of adiabatic passage between different topological orders
Xinhua Peng, Zhihuang Luo, Supeng Kou +2
Topological orders are exotic phases of matter existing in strongly correlated quantum systems, which are beyond the usual symmetry description and cannot be distinguished by local…
Construction of Arbitrary Robust One-Qubit Operations Using Planar Geometry
Tsubasa Ichikawa, Jefferson G. Filgueiras, Masamitsu Bando +3
We show how to construct an arbitrary robust one-qubit unitary operation with a control Hamiltonian of , where is a Pauli matrix and is piec…
Using the Quantum Zeno Effect for Suppression of Decoherence
Yasushi Kondo, Yuichiro Matsuzaki, Kei Matsushima +1
Projective measurements are an essential element of quantum mechanics. In most cases, they cause an irreversible change of the quantum system on which they act. However, measuremen…
