Translation of "Quantum cryptography" in German

Quantum cryptography happens to be relatively easy to implement.

This wavelength plays an important role in quantum cryptography applications.

In quantum cryptography, photons comprising quantum information are exchanged between two partners.

Quantum communication and quantum cryptography have hitherto relied mainly on single photons being the information carriers.

Moreover, Deutsche Telekom is reviewing the idea of adopting quantum cryptography communication systems.

The quantum cryptography procedure, however, takes this into account.

You really should read Quantum Cryptography.

Of these, the oldest is quantum cryptography, first suggested in 1985.

By contrast, quantum communication, the basis for quantum cryptography, uses photons as a carrier for quantum information.

In classical quantum cryptography, it is assumed that photons are exchanged between the two communication partners.

In detail, in the case of quantum cryptography, photons containing quantum information are exchanged between two partners.

Set-ups used so far have employed these fiberglass connections or direct visual connections for communication purposes employing the quantum cryptography described.

One prominent example is quantum cryptography.

Eavesdropping on a message protected by quantum cryptography cannot be done without being noticed.

Quantum cryptography is a promising and trendsetting technique to increase security in information technologies.

What is quantum cryptography?

Quantum cryptography is a method for a secure transmission of random keys, used to encrypt messages, over publicly accessible optical communication channels.

The quantum cryptography system according to claim 1, wherein the quantum channel includes a glass fiber which does not have an intermediate amplifier, wherein a conventional channel is routed over the quantum channel at a different spectral carrier frequency.

The quantum cryptography system according to claim 1, wherein the electrooptical liquid crystal modulators check the polarization setting in a quantum-transmitting fiber of the quantum channel and in subsequent other components by a measurement procedure, and wherein the electrooptical liquid crystal modulators are capable of resetting the polarization setting in conjunction with a further retardation plate.

The quantum cryptography system according to claim 1, wherein the quantum channel includes free space for transmitting individual quantum states of light, and wherein disturbances of the light which are caused by sunlight are reduced using one of absorption lines of an outer atmosphere of sun during transmissions of the individual states of the light one of through the sun?s outer atmosphere, to and from satellites, in space, and between the satellites in space.

On the other hand, it has been shown that some of these effects would be useful for possible applications such as the quantum computer or quantum cryptography.

Quantum cryptography makes data absolutely bug-proof because in contrast to classic encryption techniques it is not based on the hope that a mathematical problem can only be solved with a great amount of effort but on a physical principle.
