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…
Sumcheck-based delegation of quantum computing to rational server
Yuki Takeuchi, Tomoyuki Morimae, Seiichiro Tani
Delegated quantum computing enables a client with weak computational power to delegate quantum computing to a remote quantum server in such a way that the integrity of the server c…
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…
Verifying commuting quantum computations via fidelity estimation of weighted graph states
Masahito Hayashi, Yuki Takeuchi
The instantaneous quantum polynomial time model (or the IQP model) is one of promising models to demonstrate a quantum computational advantage over classical computers. If the IQP…
