Disordered Potts model on the diamond hierarchical lattice: Numerically exact treatment in the large-q limit
Ferenc Igloi, Loic Turban
We consider the critical behavior of the random q-state Potts model in the large-q limit with different types of disorder leading to either the nonfrustrated random ferromagnet reg…
Scattering theory of cooling and heating in opto-mechanical systems
André Xuereb, Peter Domokos, János Asbóth +2
We present a one-dimensional scattering theory which enables us to describe a wealth of effects arising from the coupling of the motional degree of freedom of scatterers to the ele…
Quantum walk on the line with quantum rings
Orsolya Kálmán, Tamás Kiss, Péter Földi
We propose a scheme to implement the one-dimensional coined quantum walk with electrons transported through a two-dimensional network of spintronic semiconductor quantum rings. The…
Practical methods for witnessing genuine multi-qubit entanglement in the vicinity of symmetric states
Geza Toth, Witlef Wieczorek, Roland Krischek +3
We present general numerical methods to construct witness operators for entanglement detection and estimation of the fidelity. Our methods are applied to detecting entanglement in…
Experimental entanglement of a six-photon symmetric Dicke state
Witlef Wieczorek, Roland Krischek, Nikolai Kiesel +3
We report on the experimental observation and characterization of a six-photon entangled Dicke state. We obtain a fidelity as high as 0.6540.024 and prove genuine six-photon e…
Qubit protection in nuclear-spin quantum dot memories
Z. Kurucz, M. W. Sørensen, J. M. Taylor +2
We present a mechanism to protect quantum information stored in an ensemble of nuclear spins in a semiconductor quantum dot. When the dot is charged the nuclei interact with the sp…
