We show that, for a large squeezing value, these states are either (almost) maximally entangled or product states depending on the value of . This peculiar behavior of entanglement is unique for infinite-dimensional Hilbert space and has consequences, e.g., for the entangling power of unitary operators in such systems. Finally, we show that, at the limit r → ∞, these states demonstrate a discontinuity attribute of entanglement. © 2010 IOP Publishing Ltd.||Source Title:||Journal of Physics A: Mathematical and Theoretical||URI:||http://scholarbank.nus.edu.sg/handle/10635/115093||ISSN:||17518113||DOI:||10.1088/1751-8113/43/18/185302|
