Entanglement signatures of topological phase transitions in a dirty Weyl semimetal
Vinícius Mohr, Shunji Tsuchiya, Andras Szabo
Three-dimensional Weyl semimetals (WSMs) constitute paradigmatic gapless topological phases whose nodal structure is stable against weak perturbations, including disorder. Two dist…
Stabilizer Rényi entropy of 3-uniform hypergraph states
Daichi Kagamihara, Shunji Tsuchiya
Nonstabilizerness, also known as magic, plays a central role in universal quantum computation. Hypergraph states are nonstabilizer generalizations of graph states and constitute a…
Measurement-Based Quantum Computation Using the Spin-1 XXZ Model with Uniaxial Anisotropy
Hiroki Ohta, Aaron Merlin Müller, Shunji Tsuchiya
We demonstrate that the ground state of a spin-1 chain with uniaxial anisotropies, single-ion anisotropy and Ising-like anisotropy , within the Haldane phase can serve…
Phase Transitions and Noise Robustness of Quantum Graph States
Tatsuya Numajiri, Shion Yamashika, Tomonori Tanizawa +3
Graph states are entangled states that are essential for quantum information processing. As experimental advances enable the realization of large-scale graph states, efficient fide…
Quantum algorithm for unstructured search of ranked targets
Kota Tani, Shunji Tsuchiya, Seiichiro Tani +1
Grover's quantum algorithm can find a marked item from an unstructured database faster than any classical algorithm, and hence it has been used for several applications such as cry…
Violation of the Leggett-Garg inequality for dynamics of a Bose-Einstein condensate in a double-well potential
Tsubasa Sakamoto, Ryosuke Yoshii, Shunji Tsuchiya
The Leggett-Garg inequality (LGI) serves as a criterion to determine the adherence of macroscopic system dynamics to macrorealism, as introduced by Leggett and Garg. A violation of…
Higgs and Nambu-Goldstone modes in condensed matter physics
Naoto Tsuji, Ippei Danshita, Shunji Tsuchiya
Collective dynamics of many particle systems is tightly linked to their underlying symmetry and phase transitions. Higgs and Nambu-Goldstone modes are, respectively, collective amp…
