"Revolutionary Chessboard Method Unleashes Quantum Dot System's Potential"

Researchers from Delft have developed a chessboard-like method to address multiple quantum dots using a combination of horizontal and vertical lines, enabling the operation of the largest gate-defined quantum dot system to date. This approach is a significant step towards scalable quantum systems for practical quantum technology. The method reduces the number of control lines required for addressing qubits, making it more feasible to scale up the number of qubits in quantum computers. Additionally, the researchers have achieved high-quality qubits with a 99.992% fidelity, opening up possibilities for quantum simulation using quantum dot systems.
