Abstract: F39.00008 : Deterministic Generation of a Traveling Cat State with a Kerr Parametric Oscillator
1:27 PM–1:39 PM
(Univ. of Tokyo)
Quantum computation with a network of Kerr parametric oscillators, or KPOs for short, has been proposed for the standard gate model [1,2] and adiabatic optimization . Such a new machine is expected to be implemented with superconducting circuits [4,5]. A remarkable feature of a KPO is the ability to generate a Schödinger cat state deterministically via quantum adiabatic evolution. However, the cat state inside the KPO seems difficult to observe because of the large Kerr effect. Here we theoretically propose a method to release the cat state from the KPO without a tunable output coupler. As a result, a traveling cat state can be generated deterministically with a KPO and observed, e.g., by homodyne detection. We will also propose a superconducting-circuit implementation of the traveling-cat generator.
