Quantum Computing

Quantum computing represents a fundamentally different approach to computation.

Rather than replacing all classical computing, quantum systems may eventually provide advantages for specialized problems that are difficult for current computers.

The IBACTP® Quantum Computing Resource Center helps professionals understand quantum concepts, future use cases, and the immediate cybersecurity implications of quantum technology.

CLASSICAL COMPUTING vs. QUANTUM COMPUTING

Classical Computing

Uses bits:

0 or 1

Uses quantum bits, or qubits.

Quantum systems can exploit properties that have no direct equivalent in classical computing.

CORE QUANTUM CONCEPTS

A quantum state may represent combinations of possibilities.

Entanglement

Quantum systems can become strongly correlated.

Quantum computation can amplify or reduce probability paths.

Measurement

Observing a quantum state produces a classical result.

Future applications may include:

Many practical applications remain experimental.

One of the most important strategic concerns involves cryptography.

Future quantum computers could threaten widely used public-key encryption techniques.

This means organizations must prepare before the risk becomes immediate.
