The next big tech will involve quantum physics.
Quantum computing
Behold your computer. Your computer represents the culmination of years of technological advancements beginning with the early ideas of
Charles Babbage
(1791-1871) and eventual creation of the first computer by German engineer
Konrad Zuse
in 1941. Surprisingly however, the high speed modern computer sitting in front of you is fundamentally no different from its gargantuan 30 ton
ancestors
, which were equipped with some 18000 vacuum tubes and 500 miles of wiring! Although computers have become more compact and considerably faster in performing their task, the task remains the same: to manipulate and interpret an encoding of binary bits into a useful computational result. A bit is a fundamental unit of information, classically represented as a 0 or 1 in your digital computer. Each classical bit is physically realized through a macroscopic physical system, such as the magnetization on a hard disk or the charge on a capacitor. A document, for example, comprised of n-characters stored on the hard drive of a typical computer is accordingly described by a string of
8n
zeros and ones. Herein lies a key difference between your classical computer and a quantum computer. Where a classical computer obeys the well understood laws of classical physics, a quantum computer is a device that harnesses physical phenomenon unique to quantum mechanics (especially
quantum interference
) to realize a fundamentally new mode of information processing. Read the rest here... starting from the 2nd paragraph.
