Abstract
A quantum circuit apparatus includes N qubits, where N is a predetermined integer of 3 or more, and a coupler, the N qubits configured to be coupled through the coupler via a many-body interaction, wherein at least one qubit out of the N qubits is configured to have a sign of a parameter representing nonlinearity of the at least one qubit different from a sign of a parameter representing nonlinearity of the coupler and/or a sign of a parameter representing nonlinearity of at least one other of the N qubits.
Claims15
A quantum circuit apparatus comprising:
- N qubits, where N is a predetermined integer of 3 or greater;
- and
- a coupler, the N qubits configured to be coupled through the coupler via a many-body interaction,
- wherein at least one qubit of the N qubits is configured to have a sign of a parameter representing nonlinearity of the at least one qubit different from a sign of a parameter representing nonlinearity of the coupler and/or a sign of a parameter representing nonlinearity of at least one other of the N qubits.
A control method of a quantum circuit that includes N qubits, where N is a predetermined integer of 3 or greater;
- and a coupler, the N qubits configured to be coupled through the coupler via a many-body interaction, the method comprising
- configuring at least one qubit of the N qubits to have a sign of a parameter representing nonlinearity thereof different from
- a sign of a parameter representing nonlinearity of the coupler and/or
- a sign of a parameter representing nonlinearity of at least one other of the N qubits.
