How quantum computing enhances data security

Overview of Quantum Computing

Quantum computing is a cutting-edge field that leverages principles of quantum mechanics to perform computations. Unlike classical computing, which relies on bits as the fundamental unit of information, quantum computing uses quantum bits, or qubits.

Quantum Bits (Qubits) vs. Classical Bits

Qubits differ from classical bits in that they can exist in multiple states simultaneously, thanks to a concept called superposition. While classical bits can only be in a state of 0 or 1, qubits can be 0, 1, or any combination of both at the same time. This superposition allows quantum computers to process vast amounts of information in parallel, leading to exponential increases in computational power.

Principles of Superposition and Entanglement

In addition to superposition, quantum computing also relies on another principle known as entanglement. Entanglement links the states of two or more qubits, regardless of the distance between them. This interconnectedness enables quantum computers to perform complex calculations and solve problems that would be infeasible for classical computers.
