Single and Entangled Photon Sources
نویسنده
چکیده
The possibility of totally secure communication through the application of quantum mechanical properties was introduced in 1984 by Bennett and Brassard in their paper, “Quantum Cryptography: Public Key Distribution and Coin Tossing”. As Bennett and Brassard outlined, quantum communication makes it impossible for an eavesdropper to intercept a message without detection by the desired parties. This phenomenon paves the way for a future of indecipherably secure communication, even with the advent of more powerful and even quantum computers. To utilize the powerful advantages of quantum communication systems, single or entangled photon sources are necessary. An outline of the theory of these sources and a subset their applications are described below.

Sources of Single and Entangled Photons
The ability to produce single photons and entangled photon pairs in desired quantum states is essential in any system intended to handle quantum information. Single photons serve as qubits in quantum computers, and the most powerful operations in those computers are performed by entangling them. Further, entangled pairs of photons are the carriers for signals in quantum-encrypted communications...
