Quantum Computing Explained: A Business Guide to the Next Computing Revolution
Quantum computing harnesses quantum mechanics principles to solve complex problems beyond classical computers' capabilities. Instead of traditional bits (0 or 1), quantum computers use qubits that can exist in multiple states simultaneously through superposition and entanglement.
Quantum Computing Fundamentals
- Qubits replace classical bits, enabling simultaneous 0 and 1 states
- Quantum gates manipulate qubits using entanglement and superposition
- Quantum circuits implement algorithms like Shor's algorithm for complex calculations
Timeline and Development
- Major companies investing millions in quantum research
- Experts predict quantum computers could crack current encryption by 2030
- IBM has created a 10-year development blueprint
- NIST announced four quantum-resistant cryptographic algorithms
- Microsoft developed new error-correction algorithms
