In a ‘quantum’ world, will science and philosophy meet?

KARACHI: There is no definitive answer to the question when the world of science and philosophy would finally meet but probably for the first time in history both are at least ready to meet through quantum physics and computing.

At a lecture organised by the Habib University on Saturday, Suhail Zubairy, a professor of physics and the inaugural holder of Munnerlyn-Heep Chair in Quantum Optics at Texas A&M University, talked about “Quantum Computing – New Frontiers”.

Dr Zubairy presented a general review of the interesting developments in the field of quantum computing and its implications.

Quantum computing represents a future where problems shall be solved much faster than by our present conventional computers. “Research in this field has generated many interesting spin-offs such as the possibility of perfectly secure communication on publicly accessible channels,” said Dr Zubairy.

The present-day transactions are safe because people can’t break codes with conventional computers. Even if they tried, it would take 80 years to break a 250-digit code. The quantum computers, however, would be able to do factorisation as well as solve the Shor’s algorithm in an instant.

The physics professor explained the assertion through an example also. “While you can find a number from any telephone directory by the name of a person, it would require a million searches if you were asked to find a name through the telephone number,” he said.

Zubairy, however, played down the hype simultaneously. “No quantum computers exist so far,” he said, “and there are very few algorithms that a quantum computer can solve.” The outcome of quantum computers is only probabilistic and this is a challenge physicists the world over have yet to overcome this.

While discussing other “impossibilities”, the professor cited his own research which showed that it was possible to exploit the magic of quantum to communicate with nothing at all between the sender and the receiver. He termed this highly counter-intuitive notion the “theory of psychic communication”.

The audience included a host of senior academics from schools, universities and engineering students, physics graduates and techies.

Despite all the “probabilities” in the field of quantum computing, this year’s Nobel Prize for physics was awarded to two scientists, who worked out a way to trap, control and study the fundamental particles of light and matter without destroying them. Professors Serge Haroche and David J. Wineland’s work could pave the way to superfast quantum computers and to measure time with greater precision than atomic clocks.

    Just like astronomy replaced astrology,chemistry replaced alchemy,its time,science and philosophy replaced religion so that people can live life in a better mannerRecommend

    Our knowledge will always be incomplete and and our beliefs will always continue to be a product of many factors beside it.

    Foundations of “Eastern” philosophy/religions (i.e upanishad and buddhism) resemble the foundations of quantum theory. Concepts of quantum physics identify with the concepts underlying these religions and philosophies. Similarities between quantum theory and philosophy merely coincidental . . . or are somehow intrinsically related (?) Who knows? :).
