Stable macroscopic quantum superpositions
F. Fröwis, W. Dür
We study the stability of superpositions of macroscopically distinct quantum states under decoherence. We introduce a class of quantum states with entanglement features similar to…
The U(1) Lattice Gauge Theory Universally Connects All Classical Models with Continuous Variables, Including Background Gravity
Ying Xu, Gemma De las Cuevas, Wolfgang Dür +2
We show that the partition function of many classical models with continuous degrees of freedom, e.g. abelian lattice gauge theories and statistical mechanical models, can be writt…
Remote Preparation of Single-Photon "Hybrid" Entangled and Vector-Polarization States
Julio T. Barreiro, Tzu-Chieh Wei, Paul G. Kwiat
Quantum teleportation faces increasingly demanding requirements for transmitting large or even entangled systems. However, knowledge of the state to be transmitted eases its recons…
14-qubit entanglement: creation and coherence
Thomas Monz, Philipp Schindler, Julio T. Barreiro +7
We report the creation of Greenberger-Horne-Zeilinger states with up to 14 qubits. By investigating the coherence of up to 8 ions over time, we observe a decay proportional to the…
Entanglement criteria and full separability of multi-qubit quantum states
Otfried Gühne
We introduce an entanglement criterion to exclude full separability of quantum states. We present numerical evidence that the criterion is necessary and sufficient for the class of…
Decoherence of many-body systems due to many-body interactions
T. Carle, H. J. Briegel, B. Kraus
We study a spin-gas model, where N_S system qubits are interacting with N_B bath qubits via many-body interactions. We consider multipartite Ising interactions and show how the eff…
