Measurements of Capacitive Coupling Within a Quadruple-Quantum-Dot Array
Understanding the interactions that couple gate-defined quantum-dot qubits is an important step to using such devices in quantum computing. For double-quantum-dot qubits with an effective charge dipole moment, a capacitive dipole-dipole interaction can yield coherent coupling between neighboring qubits. Here researchers reveal the tunability of this capacitive-coupling energy with applied …
