Like a conventional computer, a quantum computer consists of a number of memory cells whose contents are modified in a sequence of logical transformations. Unlike a conventional computer, whose memory cells are either 1 or 0, each cell in a quantum computer is started in a quantum superposition of both 1 and 0. The whole machine is a superposition of all possible combinations of memory states. As the computation proceeds, each component of the superposition individually undergoes the logic operations. It is as if an exponential number of computers, each starting with a different patterns in memory, were working on the problem simultaneously. When the computation is finished, the memory cells are examined, and an answer emerges from the wavelike interference of all the possibilities. The trick is to devise the computation so that the desired answers reinforce, while the others cancel. Hans Moravec, Robot: Mere Machine to Transcendent Mind, pp. 62-63
Welcome to my personal webspace
I have divided this blog into three sections. The first is a "commonplace book," which contains (usually in the form of quotes or poems) useful concepts, advice, or facts that I have learned. The second section contains some essays of mine. The third contains tutorials on topics such as web development.
If you wish to contact me, or to see products or projects I have worked on recently, then see the navigation menu above.
Commonplace BookA scrapbook of useful concepts and facts I have learned
All the deaths and injuries - all of them – from the mob scenes in Pakistan to the activities of the Iranian assassination squads, were directly caused by Rushdie’s enemies. None of the deaths or injuries - none of them - were caused by him, or by his friends or defenders. Yet you will notice the displacement tactic used by Berger and Dummett and the multi-culti Left, which blamed the mayhem on an abstract construct – “the Rushdie Affair.” - Christopher Hitchens, Hitch-22, pp. 269-270.
The accident of being born in a poor rather than a rich country is as arbitrary a determinant of one’s fate as the accident of being born in a poor rather than a rich family in the same country - Thomas Nagel, The Problem of Global Justice, p. 126
Always when in doubt please do send letters of commiseration; at the very least they will be appreciated and at the best they may even succeed in their apparently futile ambition of lightening the burden of bereavement. - Christopher Hitchens, Hitch-22, p. 156
