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…
