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…
Hardness of efficiently generating ground states in postselected quantum computation
Yuki Takeuchi, Yasuhiro Takahashi, Seiichiro Tani
Generating ground states of any local Hamiltonians seems to be impossible in quantum polynomial time. In this paper, we give evidence for the impossibility by applying an argument…
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…
