4. Introduction
• Quantum Cryptography, utilizing unintuitive Laws of Quantum mechanics provides us a theoretically sound and interesting
Cryptographic Methodology for future communication system.
• Electromagnetic waves such as light waves can exhibit the phenomenon of polarization, in which the direction of the electric
field vibrations is constant or varies in some definite way.
• According to Quantum theory, light waves are propagated as discrete particles known as photons. A photon is a mass less
particle, the quantum of the electromagnetic field, carrying energy, momentum, and angular momentum(or spin). The
polarization of the light is determined by the direction of the angular momentum of the photons. Therefore, spin carries the
polarization state which can be conferred as Quantum Information.
• The foundation of Quantum Cryptography lies in the Heisenberg uncertainty principle, which states that "locating a particle
in a small region of space makes the momentum of the particle uncertain; and conversely, measuring the momentum
of a particle precisely makes the position uncertain."
• This implies when measuring the polarization of a photon, the choice of what direction to measure affects all subsequent
measurements.

17. Insight: Top assignee with citation count
• By taking forward citations of all the patents into account calculated average citation frequency of patents.
• Similar analysis is done to the patents of top10 technologies.
• The average citation frequency of the patents pertaining to this technology is found to be 4.5863
• From the above graph it is clear that Fujitsu and Alcatel Lucent have good quality patents in the field Optical device,
Quantum Communication and Cryptography which are related to each other to form the vast domain of Quantum
Cryptography.
Similarly classes H04L000908Q, B82Y002000, H04L000912 are highly relevant and have good quality patents, as their average
citation frequency is more than the average citation frequency of all relevant patents.
