Hi,
my name is Roberto Bovolenta, and I?m an Italian physicist. In former
times I?ve worked in the fields of nanoscience and acoustic, and
recently I got interested, on my own, in quantum computation world.
I?ve recently published a paper on arXiv named ?Proposal for a
computation procedure based on continuous-variable post-selected
teleportation?, that you can find at this link:
http://arxiv.org/abs/1304.1892

The paper consist of a potential procedure based on the combination of
an alternative information encoding system inside the state of an
electromagnetic mode and on continuous-variable post-selected
teleportation, for speedup the computational power of a classic
computer as expected from the closed timelike curves (CTC) of David
Deutsch in his paper of 1991 ?Quantum mechanics near closed timelike
lines?.

The main peculiarity of this procedure is the following: unlike the
discrete case, thanks to the closed timelike curve via quantum post-
selection (P-CTC), we can, in principle, treat, with a single P-CTC,
an unlimited quantity of information, so would no longer be necessary
to build a complete quantum computer, since we need only a simple
classic CPU to perform the computation and to implement it in our time
loop.

Now, as we know, this ?time loop process? in theory could be
susceptible to the unavoidable experimental errors that could
compromise the entire process, and that is why I?ve developed also an
alternative scheme which first performs the entire computational
process in the classic computer, then the output measure will be
revealed in a previous instant at the end of computation.

Therefore, we could obtain a considerable simplification and benefits
in terms of realization, and personally I believe that, if the P-CTC
really had a potential usefulness for the increase of computational
power, this two schemes could be a fascinating test.
For any clarification, don?t hesitate to reply.

Best regards,
Roberto Bovolenta.
