Trusted center verification model and classical channel remote state preparation
Tomoyuki Morimae, Yuki Takeuchi
The classical channel remote state preparation (ccRSP) is an important two-party primitive in quantum cryptography. Alice (classical polynomial-time) and Bob (quantum polynomial-ti…
Polylog-overhead highly fault-tolerant measurement-based quantum computation: all-Gaussian implementation with Gottesman-Kitaev-Preskill code
Hayata Yamasaki, Kosuke Fukui, Yuki Takeuchi +2
Scalability of flying photonic quantum systems in generating quantum entanglement offers a potential for implementing large-scale fault-tolerant quantum computation, especially by…
Classically Simulating Quantum Circuits with Local Depolarizing Noise
Yasuhiro Takahashi, Yuki Takeuchi, Seiichiro Tani
We study the effect of noise on the classical simulatability of quantum circuits defined by computationally tractable (CT) states and efficiently computable sparse (ECS) operations…
Sampling of globally depolarized random quantum circuit
Tomoyuki Morimae, Yuki Takeuchi, Seiichiro Tani
The recent paper [F. Arute et al. Nature {\bf 574}, 505 (2019)] considered exact classical sampling of the output probability distribution of the globally depolarized random quantu…
Experimental demonstration of secure quantum remote sensing
Peng Yin, Yuki Takeuchi, Wen-Hao Zhang +10
Quantum metrology aims to enhance the precision of various measurement tasks by taking advantages of quantum properties. In many scenarios, precision is not the sole target; the ac…
Quantum key distribution with simply characterized light sources
Akihiro Mizutani, Toshihiko Sasaki, Yuki Takeuchi +2
To guarantee the security of quantum key distribution (QKD), several assumptions on light sources must be satisfied. For example, each random bit information is precisely encoded o…
