Abstract

We present relevant bounds for the case of weak+vacuum decoy state and one decoy state for a two-way four states Quantum Key Distribution (QKD) protocol. The numerical simulation result is significant given that an improvement in maximum secure distance of nearly twice the original one is achieved.

Two way Quantum Key Distribution protocol with Weak+Vacuum decoy state

Mohd Fared Abdul Khir, Iskandar Bahari, Abang Annuar Ehsan

We consider a practical implementation of decoy state protocol with a two way Quantum Key Distribution protocol using the Weak+Vacuum decoy state scheme. The result from numerical simulation was very encouraging given that the maximum secure distance was very close to the case of maximum theoretical limit using infinite decoy state.

Secure Communication with One Decoy State and Two Way Quantum Key Distribution Scheme

Mohd Fared Abdul Khir, Iskandar Bahari, M. N. Mohd Zain +1 more

Quantum Key Distribution (QKD) provides a mean for unconditionally secure secret key sharing for secure communication. For a practical QKD system, the recently proposed decoy state protocol has become an essential tool. In this work, we conduct numerical analysis against several bounds for one decoy state with two way QKD protocol and compare their performance in terms of key rate and maximum secure distance.

Upper bounds for the secure key rate of the decoy-state quantum key distribution

Marcos Curty, Tobias Moroder, Xiongfeng Ma +2 more

The use of decoy states in quantum key distribution (QKD) has provided a method for substantially increasing the secret key rate and distance that can be covered by QKD protocols with practical signals. The security analysis of these schemes, however, leaves open the possibility that the development of better proof techniques or better classical postprocessing methods might further improve their performance in realistic scenarios. In this paper, we derive upper bounds on the secure key rate for decoy-state QKD. These bounds are based basically only on the classical correlations established by the legitimate users during the quantum communication phase of the protocol. The only assumption about the possible postprocessing methods is that double click events are randomly assigned to single click events. Further, we consider only secure key rates based on the uncalibrated device scenario which assigns imperfections such as detection inefficiency to the eavesdropper. Our analysis relies on two preconditions for secure two-way and one-way QKD. The legitimate users need to prove that there exists no separable state (in the case of two-way QKD) or that there exists no quantum state having a symmetric extension (one-way QKD) that is compatible with the available measurements results. Both criteria have been previously applied to evaluate single-photon implementations of QKD. Here we use them to investigate a realistic source of weak coherent pulses. The resulting upper bounds can be formulated as a convex optimization problem known as a semidefinite program which can be efficiently solved. For the standard four-state QKD protocol, they are quite close to known lower bounds, thus showing that there are clear limits to the further improvement of classical postprocessing techniques in decoy-state QKD.

Erroneous signal detection and secure distance improvement in two way Quantum Key Distribution protocol with decoy state

Mohd Fared Abdul Khir, Iskandar Bahari, M. N. Mohd Zain +1 more

The erroneous signal detection characterizes the quality of alignment and stability of a Quantum Key Distribution (QKD) system. Its effect against the improvement to the maximum secure distance achievable with weak+vacuum decoy state and a two way Quantum Key Distribution protocol, namely the LM05 protocol is investigated. The result from our numerical simulation suggested that the secure distance improvement for the two key rate formulas are stable only when erroneous signal detection is at below 5%. Interestingly, at beyond 5 %, the two secure key rate formulas exhibit opposite result with one tends to increase while the other tends to decrease.

Secure communication with practical two way Quantum Key Distribution protocol and Weak+ Vacuum decoy state

Mohd Fared Abdul Khir, Iskandar Bahari

A practical implementation of a two way Quantum Key Distribution protocol namely the LM05 protocol with the Weak+Vacuum decoy state protocol having the double photon gain excluded from the final secure key rate calculation is reconsidered. The numerical analysis result has shown that the performance was better than the case when single and double photon gain was lumped.

DECOY STATE QUANTUM KEY DISTRIBUTION

Hoi‐Kwong Lo

Quantum key distribution (QKD) allows two parties to communicate in absolute security based on the fundamental laws of physics. Up till now, it is widely believed that unconditionally secure QKD based on standard Bennett-Brassard (BB84) protocol is limited in both key generation rate and distance because of imperfect devices. Here, we solve these two problems directly by presenting new protocols that are feasible with only current technology. Surprisingly, our new protocols can make fiber-based QKD unconditionally secure at distances over 100km (for some experiments, such as GYS) and increase the key generation rate from O(η2) in prior art to O(η) where η is the overall transmittance. Our method is to develop the decoy state idea (first proposed by W.-Y. Hwang in "Quantum Key Distribution with High Loss: Toward Global Secure Communication", Phys. Rev. Lett. 91, 057901 (2003)) and consider simple extensions of the BB84 protocol. This part of work is published in "Decoy State Quantum Key Distribution", . We present a general theory of the decoy state protocol and propose a decoy method based on only one signal state and two decoy states. We perform optimization on the choice of intensities of the signal state and the two decoy states. Our result shows that a decoy state protocol with only two types of decoy states—a vacuum and a weak decoy state—asymptotically approaches the theoretical limit of the most general type of decoy state protocols (with an infinite number of decoy states). We also present a one-decoy-state protocol as a special case of Vacuum+Weak decoy method. Moreover, we provide estimations on the effects of statistical fluctuations and suggest that, even for long distance (larger than 100km) QKD, our two-decoy-state protocol can be implemented with only a few hours of experimental data. In conclusion, decoy state quantum key distribution is highly practical. This part of work is published in "Practical Decoy State for Quantum Key Distribution", . We also have done the first experimental demonstration of decoy state quantum key distribution, over 15km of Telecom fibers. This part of work is published in "Experimental Decoy State Quantum Key Distribution Over 15km", .
