Alternative or Advanced
Computing
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
problems.

Reversible Computing
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.

Entropy and the Thermodynamics of Computation by Neil Gershenfeld

Quantum Computing
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.

Bulk
Spin Resonance Quantum Computation, Neil A. Gershenfeld and Isaac

since it demonstrates how to make a reliable quantum computer out of bulk
matter.

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