When people talk about the future of quantum computing, the conversation usually centers on qubit coherence, error correction, or the race toward logical processors. Power consumption is rarely mentioned. Yet it is fast becoming one of the most concrete — and most underestimated — challenges the industry will have to face. At Aqsolotl, we manufacture quantum controllers with a measured power draw of 8 to 15 W per qubit. To understand what that figure means, it helps to look
