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…
Entanglement entropy dynamics of non-Gaussian states in free boson systems: Random sampling approach
Ryui Kaneko, Daichi Kagamihara, Ippei Danshita
We develop a random sampling method for calculating the time evolution of the Rényi entanglement entropy after a quantum quench from an insulating state in free boson systems. Beca…
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…
