Quantum Computation and Information Security

Quantum Computation and Information Security

Explore quantum computation and its implications for information security in this 42-minute conference talk from CYPHERCON15. Delve into secure communication concepts, including RSA encryption and the challenges of factoring. Examine thought experiments like Schrödinger's Cat to introduce quantum bits (qubits) and their complex states. Learn about building qubits, polarizing light, and quantum key distribution. Compare classical computers built from NAND gates to quantum computers using CNOT gates and single-qubit operators. Witness an experimental demonstration of 2 qubits and understand Shor's algorithm for factoring numbers. Gain insights into the speed and potential impact of quantum algorithms on current encryption methods.
