Quantum Computing and National Security

Quantum computing is a dual-use technology with the potential to transform defense, intelligence, and cybersecurity. Unlike classical computers, which use binary (0 and 1) to process information, quantum computers use qubits, which can exist in multiple states simultaneously, making them exponentially more powerful for certain tasks.

Understanding Quantum Computing

What is Quantum Computing?

Quantum computing leverages the principles of quantum mechanics to process information in ways that classical computers cannot. It allows for superposition (where a qubit can be both 0 and 1 at the same time) and entanglement (where qubits are interconnected regardless of distance), enabling ultra-fast computation.

Classical vs. Quantum Computing

• Classical Computing: Uses bits (0 or 1) as the smallest unit of data.
• Quantum Computing: Uses qubits, which can be 0, 1, or both simultaneously, vastly increasing computational capabilities.

How Do Quantum Computers Store Information?

Quantum computers do not store information in bytes like traditional computers. Instead, they use qubits, which can encode exponentially more information due to superposition and entanglement.
