Coherent Eavesdropping Attacks in Quantum Cryptography: Nonequivalence of Quantum and Classical Key Distillation
Dagomir Kaszlikowski, Jenn Yang Lim, Leong Chuang Kwek +1
The security of a cryptographic key that is generated by communication through a noisy quantum channel relies on the ability to distill a shorter secure key sequence from a longer…
Quantum and classical advantage distillation are not equivalent
Dagomir Kaszlikowski, Lim Jenn Yang, L. C. Kwek +1
We report that, for the generation of a secure cryptographic key from correlations established through a noisy quantum channel, the quantum and classical advantage distillation pro…
Quantum Cryptography: Security Criteria Reexamined
Dagomir Kaszlikowski, Ajay Gopinathan, Yeong Cherng Liang +2
We find that the generally accepted security criteria are flawed for a whole class of protocols for quantum cryptography. This is so because a standard assumption of the security a…
Multi-Component Bell Inequality and its Violation for Continuous Variable Systems
Jing-Ling Chen, Chunfeng Wu, L. C. Kwek +3
Multi-component correlation functions are developed by utilizing d-outcome measurements. Based on the multi-component correlation functions, we propose a Bell inequality for bipart…
Tomographic Quantum Cryptography
Yeong Cherng Liang, Dagomir Kaszlikowski, Berthold-Georg Englert +2
We present a protocol for quantum cryptography in which the data obtained for mismatched bases are used in full for the purpose of quantum state tomography. Eavesdropping on the qu…
Tomographic Quantum Cryptography: Equivalence of Quantum and Classical Key Distillation
Dagmar Bruss, Matthias Christandl, Artur Ekert +3
The security of a cryptographic key that is generated by communication through a noisy quantum channel relies on the ability to distill a shorter secure key sequence from a longer…
