Negative string tension of higher-charge Schwinger model via digital quantum simulation
Masazumi Honda, Etsuko Itou, Yuta Kikuchi +1
We study some properties of generalized global symmetry for the charge- Schwinger model in the Hamiltonian formalism, which is the -dimensional quantum electrodynamics wi…
Effects of Cosine Tapering Window on Quantum Phase Estimation
Gumaro Rendon, Taku Izubuchi, Yuta Kikuchi
We provide a modification to the quantum phase estimation algorithm (QPEA) inspired on classical windowing methods for spectral density estimation. From this modification we obtain…
Vortical Quantum Memory
Kazuki Ikeda, Dmitri E. Kharzeev, Yuta Kikuchi
Quantum memory is a crucial component of a quantum information processor, just like a classical memory is a necessary ingredient of a conventional computer. Moreover, quantum memor…
Classically emulated digital quantum simulation for screening and confinement in the Schwinger model with a topological term
Masazumi Honda, Etsuko Itou, Yuta Kikuchi +2
We perform digital quantum simulation, using a classical simulator, to study screening and confinement in a gauge theory with a topological term, focusing on ()-dimensional qu…
Diagnosis of information scrambling from Hamiltonian evolution under decoherence
Tomoya Hayata, Yoshimasa Hidaka, Yuta Kikuchi
We apply a quantum teleportation protocol based on the Hayden-Preskill thought experiment to quantify how scrambling a given quantum evolution is. It has an advantage over the dire…
