Quantum physics and computers

Quantum Physics and Computers

Recent theoretical results confirm that quantum theory provides the possibility of new ways of performing efficient calculations. The most striking example is the factoring problem. It has recently been shown that computers that exploit quantum features could factor large composite integers. This task is believed to be out of reach of classical computers as soon as the number of digits in the n...

From Digital computers to quantum computers based on biological paradigms and progress in particle physics

While several paths have emerged recently in microelectronics and computing as follow-on’s to Turing architectures implemented using essentially silicon circuits, very little “Beyond Moore” research has considered, first biological processes instead of sequential instructions, and, next the implementation of these processes exploiting particle physics interactions. This combination allows e.g. ...

Quantum Physics: A Case for Anti-Realism?

quantum physics: a case for anti-realism?

the aim of the present paper is to sbo» that anti-realism in science, 1vhich has a1;guab/y become more fashionable in recentyears, contrary to tuha: its proponents assert, cannot make use of quantum mechanics and its impressiue achievements as a frump card in justifying its claims. i will argue that scientific anti-realism far from providing scientific communiry with a progressive methodologica...
