1. A quantum information processing device, comprising:
a fin;
a first layer formed on the fin; and
a second layer formed on the first layer, wherein:
the fin includes a qubit string having multiple qubits arranged in a row in a first direction, and an interaction string having multiple inter-qubit interactions arranged in a row in the first direction;
the qubit string and the interaction string are alternately arranged in a second direction that is different from the first direction;
the first layer includes a first gate electrode array disposed in the first direction to control the qubits of the qubit string, and a second gate electrode array disposed in the first direction to control the inter-qubit interaction of the interaction string;
the second layer includes a third gate electrode array disposed in the second direction, and a fourth gate electrode array disposed in the second direction adjacently to the third gate electrode array; and
the third and the fourth gate electrode arrays control a part of the multiple qubits, and a part of the multiple inter-qubit interactions, respectively.
