Complete quantum-cycle work and reset ledger
Does a driven quantum protocol deliver positive net work after state preparation, measurement, feedback, control, and reset return every resource to its initial condition?
Setup
Use the complete-cycle energy ledger. Define the system boundary and initial state, record each protocol stage, and require the working medium, controller, memory, and reservoirs to return to their declared initial conditions.
Predict first
- 1. Predict the ideal reversible net when all resources return to their initial state.
- 2. Identify which omitted controller term could reverse the sign of the result.
| Variable | Role | Unit |
|---|---|---|
| State preparation and pump work | cycle inputs | J |
| Extracted work | cycle output | J |
| Measurement, feedback, erasure, reset | control inputs | J |
| Net cyclic work and state closure | dependent decision | J and pass/hold |
Observation columns
Analyze
- 1. Does the ledger close energy at every stage?
- 2. Which resource supplies nonequilibrium free energy?
- 3. Is measurement memory reset included?
- 4. What classical protocol is the correct performance benchmark?
Conclusion frame
The protocol delivered gross ___ J but required ___ J preparation/control/reset; final state closure was ___ and complete-cycle net was ___ J versus benchmark ___.

Teach the investigation, not the interface
Learning target: Researchers evaluate quantum-energy proposals as complete driven cycles and benchmark them against classical and quantum null models.
Prepare
- • Define sign conventions and system boundaries.
- • List every controller, pump, reservoir, and memory.
- • Prepare one apparently positive partial-cycle ledger.
Facilitation moves
- • Require the final state of every resource.
- • Separate gross work from net cycle work.
- • Benchmark against an equally resourced classical protocol.
Accessibility and participation
- • Use a stage-by-stage Sankey-style ledger with numeric text.
- • Provide separate gross and net columns.
- • Allow symbolic work terms when precise values are unavailable, but require every term.
Evidence of learning
- • A closed state-and-energy cycle
- • A controller/reset ledger
- • A fair benchmarked net-work conclusion
Misconception checks
Quantum fluctuations are automatically a thermodynamic fuel.
Equilibrium fluctuations require a nonequilibrium resource, measurement/feedback, or driven boundary to yield directed work.
Reset is merely an engineering detail outside the theory.
Repeatability requires reset; its physical and information costs are part of the cycle.
Extension
Optimize one protocol under a fixed pump-energy budget and compare its net work with a classical stochastic controller.
