Difference between Supercomputing and Quantum Computing
  • Last Updated : 28 Mar, 2020

Supercomputing:
The supercomputing can be defined as the processing of highly complex problems using the very large and concentrated compute resources of supercomputer. It enables problem solving and data analysis more easily and simply. A supercomputer can be a huge machine, a big box, or a series of boxes filled with processors, memory, and storage.

Quantum Computing:
Quantum computing is refers as the quantum-mechanical phenomenon usage. These phenomena includes superposition and entanglement for performing the computation. Computer used for the computation are quantum computer. Types of quantum computing – Quantum annealing, Quantum simulations and universal quantum computing.

Let’s see the difference Between Supercomputing and Quantum Computing:

S.NO. SUPERCOMPUTING QUANTUM COMPUTING
1 Supercomputing is defined as the processing of highly complex problems using the very large and concentrated compute resources of supercomputer Quantum computing is defined as the use of quantum-mechanical phenomena such as superposition and entanglement to perform computation.
2 Supercomputers are used for supercomputing. While quantum computer are used for Quantum computing.
3 It enables problem solving and data analysis more easily and simply. It performs calculations based on the probability
4 They plays a significant role in providing national security and knowledge in scientific discovery. While, quantum computers is still a work in progress.
5 Supercomputer is a system that operates at a high compute to I/O ratio and delivers a very large number of effective computing cycles per second. Quantum computer is a computer aimed at utilizing new quantum algorithms to accelerate digital computation.
6 Common applications of supercomputing are simulation and modeling of physical phenomena such as climate change, explosions, etc. There is no real world applications of Quantum computing.
7 It is something that connects people, organizations, products and technologies. Whereas, these are about changing the notion of computation itself.
