Experimental Demonstration of the Unified Framework for the Mixed State Geometric Phase
Jiangfeng Du, Mingjun Shi, Jing Zhu +3
Geometrical phases have been applied in virtually every major branch of physics and they play an important role in topology and knot theory in mathematics and quantum computation.…
Dimensionality induced entanglement in macroscopic dimer systems
Dagomir Kaszlikowski, Wonmin Son, Vlatko Vedral
We investigate entanglement properties of mixtures of short-range spin-s dimer coverings in lattices of arbitrary topology and dimension. We show that in one spacial dimension near…
Entanglement Production in Non-Equilibrium Thermodynamics
V. Vedral
We define and analyse the concept of entanglement production during the evolution of a general quantum mechanical dissipative system. While it is important to minimise entropy prod…
Nonlocality of a single particle
Jacob Dunningham, Vlatko Vedral
There has been a great deal of debate surrounding the issue of whether it is possible for a single photon to exhibit nonlocality. A number of schemes have been proposed that claim…
Quantum Correlation Without Classical Correlations
Dagomir Kaszlikowski, Aditi Sen De, Ujjwal Sen +2
We show that genuine multiparty quantum correlations can exist on its own, without a supporting background of genuine multiparty classical correlations, even in macroscopic systems…
Controllable Quantum Switchboard
D. Kaszlikowski, L. C. Kwek, C. H. Lai +1
All quantum information processes inevitably requires the explicit state preparation of an entangled state. Here we present the construction of a quantum switchboard which can act…
When Do Superfluidity and Long Range Order Imply Entanglement?
Vlatko Vedral
We investigate tacitly assumed relationships between the concepts of super-fluidity (-conductivity), long range order and entanglement. We prove that the three are by no means equi…
Regional versus Global Entanglement in Resonating-Valence-Bond states
Anushya Chandran, Dagomir Kaszlikowski, Aditi Sen De +2
We investigate the entanglement properties of resonating-valence-bond states on two and higher dimensional lattices, which play a significant role in our understanding of various m…
Entanglement in Many-Body Systems
Luigi Amico, Rosario Fazio, Andreas Osterloh +1
The recent interest in aspects common to quantum information and condensed matter has prompted a prosperous activity at the border of these disciplines that were far distant until…
Composite Geometric Phase for Multipartite Entangled States
Mark Williamson, Vlatko Vedral
When an entangled state evolves under local unitaries, the entanglement in the state remains fixed. Here we show the dynamical phase acquired by an entangled state in such a scenar…
Spatial Entanglement From Off-Diagonal Long Range Order in a BEC
Libby Heaney, Janet Anders, Dagomir Kaszlikowski +1
We investigate spatial entanglement - particle-number entanglement between regions of space - in an ideal Bosonic gas. We quantify the amount spatial entanglement around the transi…
How much of one-way computation is just thermodynamics?
Janet Anders, Damian Markham, Vlatko Vedral +1
In this paper we argue that one-way quantum computation can be seen as a form of phase transition with the available information about the solution of the computation being the ord…
Quantumness without quantumness: entanglement as classical correlations in higher dimensions
Vlatko Vedral
I exploit the formal equivalence between the ground state of a dimensional quantum system and a d+1 dimensional classical Ising chain to represent quantum entanglement in terms…
Witnessing Macroscopic Entanglement in a Staggered Magnetic Field
Jenny Hide, Wonmin Son, Ian Lawrie +1
We investigate macroscopic entanglement in an infinite XX spin-1/2 chain with staggered magnetic field, B_l=B+e^{-iπl}b. Using single-site entropy and by constructing an entangleme…
