Continuous-time quantum walk spatial search on the Bollobás scale-free network
Tomo Osada, Bruno Coutinho, Yasser Omar +3
The scale-free property emerges in various real-world networks and is an essential property which characterizes the dynamics or features of such networks. In this work we investiga…
Simulation of a Hydrogen Atom in Laser Field Using the Time-Dependent Variational Principle
Keefer Rowan, Louis Schatzki, Timothy Zaklama +3
The time-dependent variational principle is used to optimize the linear and nonlinear parameters of Gaussian basis functions to solve the time-dependent Schrodinger equation in 1 a…
Quantum circuit for the fast Fourier transform
Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi
We propose an implementation of the algorithm for the fast Fourier transform (FFT) as a quantum circuit consisting of a combination of some quantum gates. In our implementation, a…
Scaling Hypothesis of Spatial Search on Fractal Lattice Using Quantum Walk
Rei Sato, Tetsuro Nikuni, Shohei Watabe
We investigate a quantum spatial search problem on fractal lattices, such as Sierpinski carpets and Menger sponges. In earlier numerical studies of the Sierpinski gasket, the Sierp…
Simulating complex quantum networks with time crystals
M. P. Estarellas, T. Osada, V. M. Bastidas +4
Crystals arise as the result of the breaking of a spatial translation symmetry. Similarly, translation symmetries can also be broken in time so that discrete time crystals appear.…
Tunable Microwave Single-photon Source Based on Transmon Qubit with High Efficiency
Yu Zhou, Zhihui Peng, Yuta Horiuchi +2
Single-photon sources are of great interest because they are key elements in different promising applications of quantum technologies. Here we demonstrate a highly efficient tunabl…
