Asymptotically tight security analysis of quantum key distribution based on universal source compression
Takaya Matsuura, Shinichiro Yamano, Yui Kuramochi +2
Practical quantum key distribution (QKD) protocols require a finite-size security proof. The phase error correction (PEC) approach is one of the general strategies for security ana…
Tight concentration inequalities for quantum adversarial setups exploiting permutation symmetry
Takaya Matsuura, Shinichiro Yamano, Yui Kuramochi +2
We developed new concentration inequalities for a quantum state on an -qudit system or measurement outcomes on it that apply to an adversarial setup, where an adversary prepares…
General treatment of Gaussian trusted noise in continuous variable quantum key distribution
Shinichiro Yamano, Takaya Matsuura, Yui Kuramochi +2
Continuous Variable (CV) quantum key distribution (QKD) is a promising candidate for practical implementations due to its compatibility with the existing communication technology.…
Refined finite-size analysis of binary-modulation continuous-variable quantum key distribution
Takaya Matsuura, Shinichiro Yamano, Yui Kuramochi +2
Recent studies showed the finite-size security of binary-modulation CV-QKD protocols against general attacks. However, they gave poor key-rate scaling against transmission distance…
Finite-size security proof of binary-modulation continuous-variable quantum key distribution using only heterodyne measurement
Shinichiro Yamano, Takaya Matsuura, Yui Kuramochi +2
Continuous-variable quantum key distribution (CV-QKD) has many practical advantages including compatibility with current optical communication technology. Implementation using hete…
Numerical Method for Finite-size Security Analysis of Quantum Key Distribution
Hongyi Zhou, Toshihiko Sasaki, Masato Koashi
Quantum key distribution (QKD) establishes secure links between remote communication parties. As a key problem for various QKD protocols, security analysis gives the amount of secu…
