Efficient Reconciliation with Rate Adaptive Codes in Quantum Key Distribution
Quantum key distribution (QKD) relies on quantum and classical procedures in order to achieve the growing of a secret random string —the key— known only to the two parties executing the protocol. Limited intrinsic efficiency of the protocol, imperfect devices and eavesdropping produce errors and information leakage from which the set of measured signals —the raw key— must be stripped in order t...
متن کاملPolar Codes for Quantum Key Distribution
The polar codes are a class of linear block error-correcting codes transmitted over symmetric binaryinput discrete memoryless channels [1, 2, 3]. As their length N, N = 2n, increases, their performance tends to the Shannon limit. Subsequent publications (e.g., [4, 5]) have addressed practical aspects of the polar codes such as the size length, N, of a polar code that can support a specific feas...
متن کاملExpeditious Reconciliation for Practical Quantum Key Distribution
The paper proposes algorithmic and environmental modifications to the extant reconciliation algorithms within the BB84 protocol so as to speed up reconciliation and privacy amplification. These algorithms have been known to be a performance bottleneck 1 and can process data at rates that are six times slower than the quantum channel they serve. As improvements in single-photon sources and detec...
متن کاملToward Efficient Quantum Key Distribution Reconciliation
In this paper, we propose how to construct a reconciliation method for the BB84 Quantum Key Distribution (QKD) protocol. Theoretically, it is unconditionally secure because it is based on the quantum laws of physics, rather than the assumed computational complexity of mathematical problems. BB84 protocol performances can be reduced by various errors and information leakages such as limited intr...
متن کاملProblems in application of LDPC codes to information reconciliation in quantum key distribution protocols
The information reconciliation in a quantum key distribution protocol can be studied separately from other steps in the protocol. The problem of information reconciliation can be reduced to that of distributed source coding. Its solution by LDPC codes is reviewed. We list some obstacles preventing the LDPC-based distributed source coding from becoming a more favorable alternative to the Cascade...
