Supercomputers and quantum computers are powerful instruments for performing complex calculations, problem-solving, and data analysis. In this article, we will discuss the difference between supercomputers and quantum computers to better understand both of these.
What is Supercomputer?
Seymour Cray and Boris Babayan invented the first supercomputer, known as the CDC 6600, in 1964. A supercomputer is a sort of computer with a computational speed that is a thousand times faster than the personal computers we use at home. It can complete even the most complex jobs in a matter of seconds, whereas traditional computers would take much longer. Supercomputers are the greatest choice for scientific and engineering applications due to their extremely fast processing speeds and power.
What is Quantum Computer?
A quantum computer is a device that does calculations and stores data using the principles of quantum physics. It may handle difficult computational problems more efficiently than traditional computers. Quantum computers use quantum digits(QUBITS) instead of binary digits or bits(0,1). A QUBIT can hold many values at once. Quantum computers are completely different from traditional computers and they are better than even the most powerful supercomputers. Quantum computers are widely used in several fields of technology and science, including artificial intelligence, cybersecurity, solar capture, weather forecasting, drug development, and so on.
