Tutorial: Gate-based superconducting quantum computing
Sangil Kwon, Akiyoshi Tomonaga, Gopika Lakshmi Bhai +2
In this tutorial, we introduce basic conceptual elements to understand and build a gate-based superconducting quantum computing system.
Dissipative ground-state preparation of a quantum spin chain on a trapped-ion quantum computer
Kazuhiro Seki, Yuta Kikuchi, Tomoya Hayata +1
We demonstrate a dissipative protocol for ground-state preparation of a quantum spin chain on a trapped-ion quantum computer. As a first step, we derive a Kraus representation of a…
Unveiling clean two-dimensional discrete time crystals on a digital quantum computer
Kazuya Shinjo, Kazuhiro Seki, Tomonori Shirakawa +2
In periodically driven (Floquet) systems, evolution typically results in an infinite-temperature thermal state due to continuous energy absorption over time. However, before reachi…
Quantum feedback cooling of a trapped nanoparticle by using a low-pass filter
Shuma Sugiura, Masahito Ueda
We propose a low-pass-filter (LPF) feedback control for cooling a trapped particle with a low-pass filter, which utilizes a shift of the potential caused by the feedback operation.…
Quantum conditional mutual information as a probe of measurement-induced entanglement phase transitions
Yuichi Otsuka, Kazuhiro Seki, Seiji Yunoki
We propose that the quantum conditional mutual information (QCMI), computed with a suitably chosen partition of the system, serves as a powerful probe for detecting measurement-ind…
