Off-Diagonal-Long-Range-Order Versus Entanglement
Dagomir Kaszlikowski, Marcin Wiesniak
In this short note we discuss the relation between the so-called Off-Diagonal-Long-Range-Order in many-body interacting quantum systems introduced by C. N. Yang in Rev. Mod. Phys.…
A Witness of Multipartite Entanglement Strata
Dagomir Kaszlikowski, Alastair Kay
We describe an entanglement witness for -qubit mixed states based on the properties of -point correlation functions. Depending on the degree of violation, this witness can gu…
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…
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…
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…
