Modified Grover operator for amplitude estimation

Shumpei Uno, Yohichi Suzuki, Keigo Hisanaga +4

In this paper, we propose a quantum amplitude estimation method that uses a modified Grover operator and quadratically improves the estimation accuracy in the ideal case, as in the…

Space-time breather solution for nonlinear Klein-Gordon equations

Yasuhiro Takei, Yoritaka Iwata

Klein-Gordon equations describe the dynamics of waves/particles in sub-atomic scales. For nonlinear Klein-Gordon equations, their breather solutions are usually known as time perio…

Amplitude estimation via maximum likelihood on noisy quantum computer

Tomoki Tanaka, Yohichi Suzuki, Shumpei Uno +3

Recently we find several candidates of quantum algorithms that may be implementable in near-term devices for estimating the amplitude of a given quantum state, which is a core sub-…
