Permutationally Invariant Quantum State Tomography for Fermions
Shion Yamashika, Daisuke Yamamoto
Quantum state tomography provides complete information about a quantum state, but its measurement cost generally grows exponentially with system size. In many-particle quantum simu…
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…
Dynamics of entanglement asymmetry for space-inversion symmetry of free fermions on honeycomb lattices
Ryogo Hara, Shimpei Endo, Shion Yamashika
We study the entanglement asymmetry for the space-inversion symmetry of free fermions on a two-dimensional honeycomb lattice with an on-site energy imbalance between the two sublat…
Quantum Many-Body Mpemba Effect through Resonances
Shion Yamashika, Ryusuke Hamazaki
Relaxation towards equilibrium is often assumed to be slower when a system starts farther from equilibrium, but this intuition fails in the Mpemba effect. Recent advances in contro…
Quantum Mpemba effect in long-range spin systems
Shion Yamashika, Filiberto Ares
One of the manifestations of the quantum Mpemba effect (QME) is that a tilted ferromagnet exhibits faster restoration of the spin-rotational symmetry after a quantum quench when st…
Quantum Fisher Information as a Measure of Symmetry Breaking in Quantum Many-Body Systems
Shion Yamashika, Shimpei Endo, Hiroyasu Tajima
Symmetry breaking underlies diverse phenomena from phase transitions in condensed matter to fundamental interactions in gauge theories. Despite many proposed indicators, a general…
