Motivation: Quantum Cryptography and Computing
• “Eavesdroppers Beware:
Single Photon Emission
Prepares Way for Quantum
Cryptography“
• Practical Need for Single
Photons:
• Quantum Cryptography:
Encoding information on the
polarization of single photons
• Quantum Computation:
Quantum logic gates based on
single photons
Different types of slip-stick positioners
