What’s Happening Now? Silicon-based Computation – Moore’s Law Transistors Physical limitation Then what’s next?

What is Quantum Computing? Quantum Mechanics: – “You don’t understand quantum mechanics – you just get used to it.” – Richard Feynman – Qubits – Superposition – Parallelism – Entanglement

How Does a Quantum Computer Work?

Quantum & Copyright Making an Image: – Copyright Laws: Creator holds copyright – Even if slightly altered – Using a quantum computer to generate images: Find every possible image within given parameters Is this fair? What would happen to copyright laws? Threat to artistic images? Not necessarily just images…

Quantum & Encryption RSA & Elliptic Curve Cryptology (ECC): – Used to secure: – Software updates, , online banking, digital signatures, etc. – Amount of time needed to break a strong 1024-bit RSA code – From billions of years to minutes – But quantum computers don’t have an advantage over every type of cryptography scheme – Any replacement will have some big shoes to fill
