quant-ph2026

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 N-qudit system or measurement outcomes on it that apply to an adversarial setup, where an adversary prepares…
