Is quantum computing truly more energy-efficient than supercomputers?

Xiao Huang: How significant is the energy efficiency advantage of quantum computers?

DOORM: In the Biq Lattice test case, D-Wave’s Advantage2 prototype completed the computation in under 20 minutes with an electricity cost of less than $1. In contrast, a traditional supercomputer would require nearly 1 million years for the same task, consuming more energy than the world’s total annual electricity consumption.
