Quantum Qubit Read‑out Takes Major Power‑Efficiency Leap

Arabian Post - Researchers in Sweden have created a pulse‑activated microwave amplifier that reduces power usage by a factor of ten while preserving qubit data integrity—an advance that promises to accelerate the growth of scalable quantum computers. A team at Chalmers University of Technology reports that its new low‑noise amplifier only activates during qubit read‑out pulses, cutting average power consumption to roughly one‑tenth that of current systems. By shedding the burden of constant activation, the design keeps qubits cooler and more coherent—overcoming a vital hurdle for large‑scale quantum processors. Amplification lies at the heart of quantum computing. Qubits output extremely...
