Study Notes
Quantum Physics Overview
- Quantum physics, also known as quantum mechanics, studies matter and energy at the atomic and subatomic level.
- It contrasts with classical physics by introducing concepts like wave-particle duality, superposition, and entanglement.
Key Concepts
- Wave-Particle Duality: Particles (e.g., electrons, photons) exhibit both wave-like and particle-like properties.
- Superposition: A quantum system can exist in multiple states simultaneously until measured.
- Quantum Entanglement: Linked particles' states influence each other instantaneously, regardless of distance.
- Uncertainty Principle (Heisenberg): Impossible to precisely know both a particle's position and momentum simultaneously.
Applications of Quantum Physics
Quantum Computing
- Description: Quantum computers use qubits, which utilize superposition to perform certain tasks exponentially faster than classical computers.
- Applications: Cryptography, optimization problems, drug discovery, AI/machine learning.
Quantum Communication
- Description: Exploits entanglement for secure data transmission.
- Applications: Quantum Key Distribution (QKD) – secure communication, high-speed, secure internet networks.
Quantum Sensing and Imaging
- Description: Quantum-based devices offer exceptional precision.
- Applications: High-resolution imaging (e.g., MRI), gravitational wave detection, precise atomic clocks (GPS), environmental monitoring.
Quantum Materials
- Description: Engineered materials with unique quantum properties for specific uses.

Risks and Challenges
Quantum Cryptography Risks
- Risk: Quantum computers could break current encryption methods like RSA.
- Mitigation: Developing quantum-resistant encryption (e.g., lattice-based).
Ethical and Strategic Concerns
- Risk: Unequal access to technology could create disparities or an arms race.
- Mitigation: International regulations/collaboration for equitable access and ethical use.
Technical and Financial Barriers
- Risk: Quantum tech development requires significant resources and scaling is challenging.
- Mitigation: Increased research collaboration and investment in quantum infrastructure.
Loss of Classical Assumptions
- Risk: Quantum phenomena challenge classical physics' deterministic view of reality.
- Mitigation: Improved educational outreach about quantum principles.
Unintended Consequences
- Risk: Misuse of quantum technologies in areas like surveillance or warfare.
