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…
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…
