Measuring entanglement without local addressing in quantum many-body simulators via spiral quantum state tomography
Giacomo Marmorini, Takeshi Fukuhara, Daisuke Yamamoto
Quantum state tomography serves as a key tool for identifying quantum states generated in quantum computers and simulators, typically involving local operations on individual parti…

Rényi entropy of the permutationally invariant part of the ground state across a quantum phase transition
Yuki Miyazaki, Giacomo Marmorini, Nobuo Furukawa +1
We investigate the role of the permutationally invariant part of the density matrix (PIDM) in capturing the properties of the ground state of the system during a quantum phase tran…
