Generation of a single ion large oscillator
Ryoichi Saito, Takashi Mukaiyama
We demonstrate the generation of a trapped ion oscillator having large oscillation amplitude of . Applying an offset voltage to the ion trap electrode helped achieve…
Phonon-number-resolving Detection of Multiple Local Phonon Modes in Trapped Ions
Ryutaro Ohira, Takashi Mukaiyama, Kenji Toyoda
We propose and demonstrate phonon-number-resolving detection of the multiple local phonon modes in a trapped-ion chain. To mitigate the effect of phonon hopping during the detectio…
Quantum walks of a phonon in trapped ions
Masaya Tamura, Takashi Mukaiyama, Kenji Toyoda
Propagation and interference of quantum-mechanical particles comprise an important part of elementary processes in quantum physics, and their essence can be modeled using a quantum…
Breaking rotational symmetry in a trapped-ion quantum tunneling rotor
Ryutaro Ohira, Takashi Mukaiyama, Kenji Toyoda
A trapped-ion quantum tunneling rotor (QTR) is in a quantum superposition of two different Wigner crystal orientations. In a QTR system, quantum tunneling drives the coherent trans…
