Multi-qubit controlled gate with optimal T-count
Soichiro Yamazaki, Seiseki Akibue
Controlled gates are key components in various quantum algorithms. Improving on the prior work of Gosset et al., we show that, for an allowed error , $3\log_2(1/\varep…
Quantum simulation of Burgers turbulence: Nonlinear transformation and direct evaluation of statistical quantities
Fumio Uchida, Koichi Miyamoto, Soichiro Yamazaki +2
Fault-tolerant quantum computing is a promising technology to solve linear partial differential equations that are classically demanding to integrate. It is still challenging to so…
Clifford+V synthesis for multi-qubit unitary gates
Soichiro Yamazaki, Seiseki Akibue
We developed a general framework for synthesizing target gates by using a finite set of basic gates, which is a crucial step in quantum compilation. When approximating a gate in SU…
Quantum algorithm for collisionless Boltzmann simulation of self-gravitating systems
Soichiro Yamazaki, Fumio Uchida, Kotaro Fujisawa +2
The collisionless Boltzmann equation (CBE) is a fundamental equation that governs the dynamics of a broad range of astrophysical systems from space plasma to star clusters and gala…
Quantum algorithm for the Vlasov simulation of the large-scale structure formation with massive neutrinos
Koichi Miyamoto, Soichiro Yamazaki, Fumio Uchida +2
Investigating the cosmological implication of the fact that neutrino has finite mass is of importance for fundamental physics. In particular, massive neutrino affects the formation…
