n a major advance for quantum computing, researchers at the University of Sydney have developed a cryogenic control chip that can operate directly next to quantum bits, or qubits, at near absolute zero.

The breakthrough solves one of the biggest challenges in building large-scale quantum computers, keeping quantum information both stable and accessible.

The research outlines a new chip design that can function at milli-kelvin temperatures, just above absolute zero, without disturbing the fragile quantum states.
