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…
Simplest fidelity-estimation method for graph states with depolarizing noise
Tomonori Tanizawa, Yuki Takeuchi, Shion Yamashika +2
Graph states are entangled states useful for several quantum information processing tasks such as measurement-based quantum computation and quantum metrology. As the size of graph…
Rényi entanglement entropy after a quantum quench starting from insulating states in a free boson system
Daichi Kagamihara, Ryui Kaneko, Shion Yamashika +4
We investigate the time-dependent Rényi entanglement entropy after a quantum quench starting from the Mott-insulating and charge-density-wave states in a one-dimensional free boson…
Entanglement propagation in thermalization of an isolated quantum system
Ryosuke Yoshii, Shion Yamashika, Shunji Tsuchiya
We study dynamics of entanglement in the thermalization process of an isolated quantum many-body system. We propose a simple setup for measuring the propagation speed of entangleme…
