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 …

Measurement-based state preparation of Kerr parametric oscillators

2022 · arXiv (Cornell University)

Kerr parametric oscillators (KPOs) have attracted increasing attention in terms of their application to quantum information processing and quantum simulations. The state preparation and measurement of KPOs are typical requirements when they are used as …
