Electric circuits for universal quantum gates and quantum Fourier transformation
Motohiko Ezawa
Universal quantum computation may be realized based on quantum walk, by formulating it as a scattering problem on a graph. In this paper, we simulate quantum gates through electric…
Current-Induced Helicity Reversal of a Single Skyrmionic Bubble Chain in a Nanostructured Frustrated Magnet
Zhipeng Hou, Qiang Zhang, Xichao Zhang +14
Helicity indicates the in-plane magnetic-moment swirling direction of a skyrmionic configuration. The ability to reverse the helicity of a skyrmionic bubble via purely electrical m…
Dynamics of an elliptical ferromagnetic skyrmion driven by the spin-orbit torque
Jing Xia, Xichao Zhang, Motohiko Ezawa +3
Magnetic skyrmion is a promising building block for developing information storage and computing devices. It can be stabilized in a ferromagnetic thin film with the Dzyaloshinskii-…
Antiferromagnetic Skyrmion-Based Logic Gates Controlled by Electric Currents and Fields
Xue Liang, Jing Xia, Xichao Zhang +6
Antiferromagnets are promising materials for future spintronic applications due to their unique properties including zero stray fields, robustness versus external magnetic fields a…
Electric-circuit simulation of the Schrödinger equation and non-Hermitian quantum walks
Motohiko Ezawa
Recent progress has witnessed that various topological physics can be simulated by electric circuits under alternating current. However, it is still a nontrivial problem if it is p…
Non-Abelian braiding of Majorana-like edge states and topological quantum computations in electric circuits
Motohiko Ezawa
Majorana fermions subject to the non-Abelian braid group are believed to be the basic ingredients of future topological quantum computations. In this work, we propose to simulate M…
