Demonstrating Bayesian Quantum Phase Estimation with Quantum Error Detection
Kentaro Yamamoto, Samuel Duffield, Yuta Kikuchi +1
Quantum phase estimation (QPE) serves as a building block of many different quantum algorithms and finds important applications in computational chemistry problems. Despite the rap…
Realization of quantum signal processing on a noisy quantum computer
Yuta Kikuchi, Conor Mc Keever, Luuk Coopmans +2
Quantum signal processing (QSP) is a powerful toolbox for the design of quantum algorithms and can lead to asymptotically optimal computational costs. Its realization on noisy quan…
Predicting Gibbs-State Expectation Values with Pure Thermal Shadows
Luuk Coopmans, Yuta Kikuchi, Marcello Benedetti
The preparation and computation of many properties of quantum Gibbs states is essential for algorithms such as quantum semidefinite programming and quantum Boltzmann machines. We p…
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…
