Investigation of controls of a superconducting quantum parametron under a strong pump field
2020 · arXiv (Cornell University)
Pumped at approximately twice the natural frequency, a Josephson parametric oscillator called parametron or Kerr parametric oscillator shows self-oscillation. Quantum annealing and universal quantum computation using self-oscillating parametrons as qubits were proposed. However, controls of …

Anonymous Quantum Sensing
2022 · Journal of the Physical Society of Japan
A lot of attention has been paid to a quantum-sensing network for detecting magnetic fields in different positions. Recently, cryptographic quantum metrology was investigated where the information of the magnetic fields is transmitted in a …

Catastrophic failure of quantum annealing owing to non-stoquastic Hamiltonian and its avoidance by decoherence
2022 · arXiv (Cornell University)
Quantum annealing (QA) is a promising method for solving combinatorial optimization problems whose solutions are embedded into a ground state of the Ising Hamiltonian. This method employs two types of Hamiltonians: a driver Hamiltonian and …

Unitary-transformed projective squeezing: applications for circuit-knitting and state-preparation of non-Gaussian states
2024 · arXiv (Cornell University)
Continuous-variable (CV) quantum computing is a promising candidate for quantum computation because it can, even with one mode, utilize infinite-dimensional Hilbert spaces and can efficiently handle continuous values. Although photonic platforms have been considered as …
