Preparing ground states of the XXZ model using the quantum annealing with inductively coupled superconducting flux qubits
Takashi Imoto, Yuya Seki, Yuichiro Matsuzaki
Preparing ground states of Hamiltonians is important in the condensed matter physics and the quantum chemistry. The interaction Hamiltonians typically contain not only diagonal but…
Vector DC magnetic-field sensing with reference microwave field using perfectly aligned nitrogen-vacancy centers in diamond
Takuya Isogawa, Yuichiro Matsuzaki, Junko Ishi-Hayase
The measurement of vector magnetic fields with high sensitivity and spatial resolution is important for both fundamental science and engineering applications. In particular, magnet…
Identification of different types of high-frequency defects in superconducting qubits
Leonid V. Abdurakhimov, Imran Mahboob, Hiraku Toida +3
Parasitic two-level-system (TLS) defects are one of the major factors limiting the coherence times of superconducting qubits. Although there has been significant progress in charac…
Error-Mitigated Quantum Metrology via Virtual Purification
Kaoru Yamamoto, Suguru Endo, Hideaki Hakoshima +2
Quantum metrology with entangled resources aims to achieve sensitivity beyond the standard quantum limit by harnessing quantum effects even in the presence of environmental noise.…
Quantum annealing with twisted fields
Takashi Imoto, Yuya Seki, Yuichiro Matsuzaki and +1
Quantum annealing is a promising method for solving combinational optimization problems and performing quantum chemical calculations. The main sources of errors in quantum annealin…
Emergence of Hilbert Space Fragmentation in Ising Models with a Weak Transverse Field
Atsuki Yoshinaga, Hideaki Hakoshima, Takashi Imoto +2
The transverse-field Ising model is one of the fundamental models in quantum many-body systems, yet a full understanding of its dynamics remains elusive in higher than one dimensio…
