Energy efficiency of a quantum computer is defined as the number of algorithms it can run per unit of energy consumed, including all hardware overheads.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We define the energy efficiency of a quantum computer as the ratio of the number of algorithms it can perform during a given time over the energy consumed by the hardware during this time.

C2weakest assumption

That the energy consumption estimates for each platform, including overheads from cooling, control systems, and algorithm compilation, are accurate and representative based on expert insights.

C3one line summary

A new definition of quantum computer energy efficiency is introduced and applied to five major qubit platforms, yielding concrete consumption estimates for current systems and a benchmarking framework for future architectures.
