Double entanglement and quantum cryptography
We propose a quantum transmission based on bi-photons which are doubly-entangled both in polarisation and phase. This scheme finds a natural application in quantum cryptography, where we show that an eventual eavesdropper is bound to introduce a larger error on the quantum communication than for a single entangled bi-photon communication, when he steels the same information.
متن کاملEntanglement and Quantum Cryptography
Quantum cryptography is one of the most important quantum information applications. The present thesis covers several topics on quantum cryptography, such as the security analysis of quantum channels for key distribution protocols and the study of quantum cloning. First, we introduce a general formalism to characterize the cryptographic properties of quantum channels in the realistic scenario w...
متن کاملEntanglement versus Disentanglement: Quantum Cryptography
In alternative disentanglement based quantum cryptosystem, classical channel cannot be used when the system is protected by no-cloning principle. But for the similar security criterion , it is discussed that classical channel can be used in alternative entanglement based quantum cryptosystem. A prototype of conventional entanglement based cryptosystem is recovered from alternative entanglement ...
متن کاملQuantum cryptography with interferometric quantum entanglement
We provide a theoretical analysis of a quantum interferometric method in quantum cryptography based on the non-local nature of quantum entanglement which is currently being implemented in the laboratory . 1 . Introduction In recent years quantum mechanics has provided a new approach and new tools to solve the problem of secure communications as well as other tasks of modern cryptography [1] . T...
متن کاملMultiphoton entanglement concentration and quantum cryptography.
Multiphoton states from parametric down-conversion can be entangled both in polarization and photon number. Maximal high-dimensional entanglement can be concentrated postselectively from these states via photon counting. This makes them natural candidates for quantum key distribution, where the presence of more than one photon per detection interval has up to now been considered undesirable. We...
