All you need is the universal correlation detector: A unified approach to universalize communication protocols over quantum channels

Kaito Watanabe, Takaya Matsuura, Ryuji Takagi

Constructing optimal quantum information protocols without complete knowledge of the underlying states or channels is a central challenge. We address this challenge by developing u…

Universal classical-quantum channel resolvability and private channel coding

Takaya Matsuura, Masahito Hayashi, Min-Hsiu Hsieh

We address the problem of constructing fully universal private channel coding protocols for classical-quantum (c-q) channels. Previous work constructed universal decoding strategie…

Logical channel for heralded and pure loss with the Gottesman-Kitaev-Preskill code

Tom B. Harris, Takaya Matsuura, Ben Q. Baragiola +1

Photon loss is the dominant source of noise in optical quantum systems. The Gottesman-Kitaev-Preskill (GKP) bosonic code provides significant protection; however, even low levels o…

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…

Continuous-Variable Fault-Tolerant Quantum Computation under General Noise

Takaya Matsuura, Nicolas C. Menicucci, Hayata Yamasaki

The quantum error-correcting code in the continuous-variable (CV) system attracts much attention due to its flexibility and high resistance against specific noise. However, the the…

Linear-optical quantum computation with arbitrary error-correcting codes

Blayney W. Walshe, Ben Q. Baragiola, Hugo Ferretti +11

High-rate quantum error correcting codes mitigate the imposing scale of fault-tolerant quantum computers but require efficient generation of non-local, many-body entanglement. We p…
