the paper is this one, I suppose

http://arxiv.org/abs/quant-ph/0302179

it was expected that the vacuum behaves

as a noisy channel

http://arxiv.org/abs/quant-ph/0301065

and in general entanglements are sensible

to Lorentzian boosts (but not much)

http://arxiv.org/abs/quant-ph/0302095

http://arxiv.org/abs/quant-ph/0205179

and unforfutanely quantum entropy/information

is not a Lorentz covariant concept

http://arxiv.org/abs/quant-ph/0212023

bbbut, and this are the good news,

there are detailed papers (J. Hardy)

about the possibility of entanglement

between 'usual' quantum states and

'vacuum' states, like i.e.

psi = m |1,a>|0,b> + n |0,a>|1,b> + p |0,a>|0,b>

where |1,a> and |0,a>

are one-particle and vacuum state directed to a-lice

and |1,b> and |0,b> ... directed to b-ob
