What is quantum computing?"A fundamentally new mode
of information processing that can be performed only by harnessing physical
phenomena unique to quantum
mechanics (especially quantum interference). "

"Today, the bit is king. A conventional computer is just a series of
hundreds of millions of switches whose on and off positions represent the
values 1 and 0. And every operation a computer performs, whether calculating
your waiter's tip or simulating the explosion of a nuclear warhead, comes
down to a series of actions that flick those switches from 0 to 1 and back
again.
Familiar stuff. But in a Q[uantum] C[omputer], the bit is upgraded to a
quantum bit, or qubit, that doesn't need to choose between 1 and 0. It can
be both at once. As a result, a memory array of n qubits can represent
every number between 1 and 2n simultaneously."

This new kind of thinking about information is already occurring in simulators
even though large scale quantum computers are not available.
"Since there is not yet
a physical quantum computer of any significant size, a simulator allows
for the development of quantum algorithms without such a machine at hand."

This is a chart I found online
portraying information. It looks like a computer motherboard. This
chart shows the influence that our perceptions of the digital world has
on how we visualize and display information. Post QC I think this
notion will change. We won't think of connections in terms of line
of copper or cables but as encompassing spheres. The notion that allows
for molecules to effect one another instantaneously is called "entanglement"
for a very good reason. In side the QC's of the future electronic
components won't be connected; they will be entangled. This will change
how we visualize information; perhaps ideas will be represented over lapping
or absent the neat and tidy boxes that current system designs create.
