Controlled probabilistic quantum key distribution using a ground state

Controlled probabilistic quantum key distribution using a ground state In this paper, we propose two controlled probabilistic quantum key distribution protocols with AKLT states. An AKLT state is a gapped ground state with minimum energy, and owing to the properties of this special state, our proposed protocols incorporate not only the measurement uncertainty in quantum phenomena (entanglement swapping with 1/4 probability) but also additional randomness (Bell measurement on two physical particles with 1/3 probability), in comparison with other PQKD schemes. Therefore, our protocols are more suitable for use by two mutually untrusted communicants, with no authenticated intermediate channel, allowing them to obtain an unpredictable, and therefore secure, key. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

Abstract

In this paper, we propose two controlled probabilistic quantum key distribution protocols with AKLT states. An AKLT state is a gapped ground state with minimum energy, and owing to the properties of this special state, our proposed protocols incorporate not only the measurement uncertainty in quantum phenomena (entanglement swapping with 1/4 probability) but also additional randomness (Bell measurement on two physical particles with 1/3 probability), in comparison with other PQKD schemes. Therefore, our protocols are more suitable for use by two mutually untrusted communicants, with no authenticated intermediate channel, allowing them to obtain an unpredictable, and therefore secure, key.
