  The equivalence of 1 bit of information to entropy was given by Landauer in
1961 as kln2, k the Boltzmann constant. Erasing information implies heat
dissipation and the energy of 1 bit would then be (the Landauers limit) kT ln
2, T being the ambient temperature. From a quantum-cosmological point of view
the minimum quantum of energy in the universe corresponds today to a
temperature of 10^(-29) degrees K, probably forming a cosmic background of a
Bose condensate [1]. Then, the bit with minimum energy today in the Universe is
a quantum of energy 10^(-45)ergs, with an equivalent mass of 10^(-66)g. Low
temperature implies low energy per bit and, of course, this is the way for
faster and less energy dissipating computing devices. Our conjecture is this:
the possibility of a future access to the CBBC (a coupling/channeling?) would
mean a huge jump in the performance of these devices.
