What is Quantum Computing?
Quantum computing is a groundbreaking approach to computation that leverages the principles of quantum mechanics to process information in ways that classical computers cannot. Unlike traditional computers, which use bits as the smallest unit of data (0s and 1s), quantum computers use quantum bits, or qubits. Qubits can exist in multiple states simultaneously—a property known as superposition—and can be entangled with one another, meaning the state of one qubit can depend on the state of another, even across large distances.
I like to think of quantum computing as a completely new way of processing data—a system that can perform calculations exponentially faster than our current computers for certain complex problems. Its potential to solve issues in optimization, cryptography, simulation, and data analysis could usher in a new era of technological innovation.
