Computers come in various sizes, from those
installed in microbots or brain implants to mainframe
supercomputers capable of running powerful AIs.
Older computers are based on molecular circuits connected
by carbon nanotubes. These circuits use bacteriaderived
bacteriorhodopsin or other proteins that undergo
fast, predictable chemical changes when illuminated. Stabilized
into lattice structures, they create nanoscale optical
switching systems with higher information densities
than silicon-based electronics. These are coupled with
holographic memory and data-storage systems that have
the advantage of large capacity and instant data search
and retrieval.

Newer computers store information in the form
of localized conformation changes or charge separations
on a macromolecular framework. A macromolecular
memory unit the size of a sugar cube can store
terabytes of data. Tiny molecular computers control
microbots and are used in bionanomachines.

Quantum computers are the cutting edge of parallel
information processing. Quantum computers do calculations
using atoms in “up” or “down” spin states to
represent bits of information. Due to quantum uncertainty
effects, each atom does not simply represent one
bit, as in a traditional computer. Instead, each “qubit”
can be both up and down at once. This allows it to (in a
sense) do all possible calculations at the same time until
the act of measuring the qubits stops the calculating
process. In practice, quantum computers can solve
problems that are otherwise extremely time-consuming.
The disadvantage of quantum computers is that
they need to be heavily shielded to prevent external
radiation from affecting them. The first quantum computers
were incredibly bulky and fragile, reminiscent of
computers in the 1950s. Newer systems are somewhat
more compact, but they remain very heavy and limited
to large mainframe devices.

Other forms of information processing and data storage
may be on the horizon. Some smaller computers use
nanofactured “rod-logic” systems that resemble a microscopic
version of Charles Babbage’s original prototype
mechanical computer. At the other extreme, Hawking
Industries envisions supercomputers utilizing properties
of mini black holes or foamed space-time.
