Behold the computer. The greatest, ultimate invention across multiple eras. The grand culmination of brilliant work by the greatest thinkers, scientists, engineers and inventors of the past century. How far have we come from the difference engine of Charles Babbage; to the first computer that occupied a whole room; to the multi-core, powerful compact computers on the shelves today. Very far indeed, right? Wrong! The high-speed, modern computer that sits in front of you is fundamentally no different than Babbage’s difference engine of nearly 200 years ago. The first computer used binary and the most modern computer today uses binary. All we have done in classical computer development is make them more compact and increase the number of transistors on a processor chip. Processing is still done using bits. A bit is still represented by 1’s and 0’s as it was centuries ago.
The classical computer , as the name implies, is classical. Step to a new breed of computing, one that differs radically from the very essence of computers and binary as we know it. An evolved breed…behold the quantum computer. A dynamic new fascinating field that is being pioneered as you read these words. Forget bits, binary and logic gates. Welcome to the world of Qubits, Quantum Gates and Quantum circuits & algorithms. Welcome to Quantum Computing!
