David Westenberger Lucas Zurek 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, email, 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 What Does a Quantum Computer Look Like? • http://www.youtube.com/watch?v=VyX8E4KU kWw Sources • http://torrentfreak.com/could-quantum-computing-kill-copyright-110731/ • http://www.howstuffworks.com/quantum-computer.htm • http://www.copyright.gov/help/faq/faq-fairuse.html • http://www.youtube.com/watch?v=VyX8E4KUkWw • http://spectrum.ieee.org/computing/software/cryptographers-take-on-quantumcomputers
