Qubit-efficient embedding of parity-encoded Hamiltonians in quantum annealers
Ryoji Miyazaki
The Sourlas-Lechner-Hauke-Zoller (SLHZ) scheme for quantum annealing uses the parity to encode logical variables and has several advantages, but it has not been implemented for lar…
Spin Model for Quantum Annealing with Kerr Parametric Oscillators
Leo Stenzel, Roeland ter Hoeven, Ryoji Miyazaki +3
Coherent states offer a promising path for near-term quantum computing due to their inherent protection against bit-flip noise. However, their large photon numbers can be challengi…
Four-body coupler for superconducting qubits based on Josephson parametric oscillators
Ryoji Miyazaki, Tsuyoshi Yamamoto
We theoretically propose a circuit of the four-body coupler for superconducting qubits based on Josephson parametric oscillators (JPOs). Our coupler for the four-body interaction h…
Universal quantum computation using quantum annealing with the transverse-field Ising Hamiltonian
Takashi Imoto, Yuki Susa, Ryoji Miyazaki +1
Quantum computation is a promising emerging technology, and by utilizing the principles of quantum mechanics, it is expected to achieve faster computations than classical computers…
Quantum Image Denoising: A Framework via Boltzmann Machines, QUBO, and Quantum Annealing
Phillip Kerger, Ryoji Miyazaki
We investigate a framework for binary image denoising via restricted Boltzmann machines (RBMs) that introduces a denoising objective in quadratic unconstrained binary optimization…
Demonstration of the excited-state search on the D-wave quantum annealer
Takashi Imoto, Yuki Susa, Ryoji Miyazaki +2
Quantum annealing is a way to prepare an eigenstate of the problem Hamiltonian. Starting from an eigenstate of a trivial Hamiltonian, we slowly change the Hamiltonian to the proble…
