Coherent control of a local phonon in trapped ions using dynamical decoupling
Ryutaro Ohira, Shota Kume, Kenji Toyoda
In this paper, we present a dynamical decoupling (DD) technique to coherently control the dynamics of a single local phonon in trapped ions. A 2 rotation at a motional sideband…
Evaluating states in trapped ions with local correlation between internal and motional degrees of freedom
Silpa Muralidharan, Ryutaro Ohira, Shota Kume +1
We propose and demonstrate a scalable scheme for the simultaneous determination of internal and motional states in trapped ions with single-site resolution. The scheme is applied t…
Polariton blockade in the Jaynes-Cummings-Hubbard model with trapped ions
Ryutaro Ohira, Shota Kume, Hiroki Takahashi +1
We have experimentally observed the dynamics of a single polariton and two polaritons in a two-ion chain. By driving two trapped ions at a motional blue-sideband transition, we rea…
Blockade of phonon hopping in trapped ions in the presence of multiple local phonons
Ryutaro Ohira, Shota Kume, Kyoichi Takayama +3
Driving an ion at a motional sideband transition induces the Jaynes--Cummings (JC) interaction. This JC interaction creates an anharmonic ladder of JC eigenstates, resulting in the…
