Abstract
Quantum processors having qubits with tunable capacitance are provided. The qubits include Josephson junctions shunted by capacitors and are tunably coupled to capacitance loops such that the resonant frequencies of the qubits and capacitance loops avoid entanglement with each other. Methods for tuning the capacitance of such qubits by varying the coupler's coupling strength are provided. These methods include methods for calibrating qubits' capacitance.
