Information processing in some form or
another is essential for survival of all organisms, and the computational
requirements grow as the organisms and their environment becomes more complex.
Computing is extremely important for nearly all technologies involved in
transhumanism, either on the design stage or as an integral part of the
system. This makes it very interesting to study just how powerful computers
can become and if it is possible to use exotic architectures to solve specialised

Due to thermodynamic constraints most computations dissipate energy.
By using reversible systems, this dissipation can be minimized, something
that will be necessary in order to build nanocomputers.

Quantum computation uses the nonintuitive effects of quantum mechanics
to do computations much faster than normal Turing computers - assuming
quantum computers can be built in practice.

Related to quantum computation is quantum cryptography, the use of quantum
properties to create strong encryption.

Since electrical signals move slower than light, it would appear reasonable
to try to develop computers based on light instead of electrons.
