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…
