Quantum computing a revolutionary concept in the field of information technology has garnered significant attention in recent years. Unlike classical computers that rely on bits to process information quantum computers utilize quantum bits or qubits which can exist in multiple states simultaneously. This unique property enables quantum computers to perform complex calculations at an unprecedented speed promising breakthroughs in various domains. However the current availability of quantum computers is still limited primarily due to technological constraints and the intricate nature of quantum mechanics.

Introduction to Quantum Computers

Quantum computers leverage principles of quantum mechanics to process information. Unlike classical computers that use binary digits or bits (0s and 1s) quantum computers employ qubits which can represent both 0 and 1 simultaneously due to superposition and entanglement. This capability allows quantum computers to handle massive datasets and solve intricate problems that are infeasible for classical computers.

Explanation of Quantum Supremacy

Quantum supremacy refers to the point where a quantum computer can outperform the most powerful classical computers in certain tasks. Achieving quantum supremacy is a significant milestone in the development of quantum computing and signifies the potential superiority of quantum systems in specific applications.
