This feature does not exist in any previous QKD protocols.

It is more difficult for the adversary Eve to know the signal information with entangled photons in a spontaneous parametric down conversion (SPDC) source The verification of the integrity of encryption/decryption is possible due to the unique mathematical property of a Fibonacci or Lucas matrix.

Therefore, it is desirable to devise a more practical approach of encoding high dimensional states into a photon.

On the one hand, spontaneous parametric down conversion (SPDC) is a simple way to produce squeezed and polarization-entangled light.

However, most QKD protocols suffer from its relatively low rate of key generation, limiting its widespread applications in deployment.

This is caused by the nature of quantum computing where it uses polarization to encode only one qubit for each photon.
