Analytical formulation of the second-order derivative of energy for orbital-optimized variational quantum eigensolver: application to polarizability
Yuya O. Nakagawa, Jiabao Chen, Shotaro Sudo +2
We develop a quantum-classical hybrid algorithm to calculate the analytical second-order derivative of the energy for the orbital-optimized variational quantum eigensolver (OO-VQE)…
Simulating Time Evolution with Fully Optimized Single-Qubit Gates on Parameterized Quantum Circuits
Kaito Wada, Rudy Raymond, Yu-ya Ohnishi +4
We propose a novel method to sequentially optimize arbitrary single-qubit gates in parameterized quantum circuits for simulating real and imaginary time evolution. The method utili…
Thermal blurring of event-by-event fluctuations provoked by rapidity conversion
Yutaro Ohnishi, Masakiyo Kitazawa, Masayuki Asakawa
We study the effect of thermal blurring caused by the use of (momentum-space) rapidity as a proxy of coordinate-space rapidity in experimental measurements of conserved charge fluc…
