Abstract
A quantum cryptography system [100] may include a transmitter [110] configured to generate entangled first and second photons, modulate and detect the first photon, and transmit detection information and the second photon. The system [100] may also include a receiver [160] configured to modulate the second photon. The receiver [160] may also be configured to detect the second photon based on the detection information.
