Simulation of vibrational dynamics using qubits and qudits
Erik Lötstedt, Erik Lötstedt, Kaoru Yamanouchi
We investigate the quantum computing of the vibrational dynamics of CO and HO by constructing the vibrational third-order anharmonic Hamiltonian in qubit and qudit form by…

Comparison of encoding schemes for quantum computing of spin chains
Erik Lötstedt, Kaoru Yamanouchi
We compare four different encoding schemes for the quantum computing of spin chains with a spin quantum number : a compact mapping, a direct (or one-hot) mapping, a Dicke ma…

Cancellation of phonon hopping in trapped ions by modulation of the trap potential
Takanori Nishi, Kaoru Yamanouchi, Ryoichi Saito +1
The local modes of trapped ions can be used to construct an analog quantum simulator and a digital quantum computer. However, the control of the phonon hopping remains difficult be…
