This paper reframes the feasibility of fault-tolerant quantum computing by linking objective probability to tangible resource costs like energy and time, challenging decades-old assumptions about error correction thresholds. By identifying specific measurable metrics such as watts per decade of suppressed logical errors, it proposes a path toward empirically testing these theoretical limits using current hardware. This work shifts the discourse from abstract noise models to concrete physical constraints on quantum state realization.
Objective Probability Links Quantum Fault Tolerance to Resource Demand

This paper connects objective probability—resources needed to realize a state—to fault-tolerant quantum computing (FTQC).
The long-running debate over whether practical fault-tolerant quantum computing is achievable may hinge on a surprisingly simple question: how much energy does it actually take? A new analysis reinterprets the foundational Threshold Theorem not as a statement about error correction, but as a claim that error-corrected states are limited by available resources. Author Amit Hagar of Indiana University builds on work begun in 2011 with Giuseppe Sergioli, proposing that the probability…
