Checkmate! Quantum Computing Breakthrough Via Scalable Quantum Dot Chessboard

Posted by in categories: computing, quantum physics

Researchers have developed a way to address many quantum dots with only a few control lines using a chessboard-like method. This enabled the operation of the largest gate-defined quantum dot system ever. Their result is an important step in the development of scalable quantum systems for practical quantum technology.

Quantum dots can be used to hold qubits, the foundational building blocks of a quantum computer. Currently, each qubit requires its own addressing line and dedicated control electronics. This is highly impractical and in stark contrast with today’s computer technology, where billions of transistors are operated with only a few thousand lines.
