我们证明，在量子理论的数学框架中，经典鸽巢原理可能比之前建议的更直接地被违反，即在更接近该原理的传统陈述的环境中。我们描述了悖论的反事实推理如何在操作上基于对鸽子在环境中留下的微小足迹的分析。在确定了最近量子鸽巢效应实验的缺点后，我们认为仍然需要对鸽巢原理进行明确的实验违反，并提出使用现代量子计算硬件的实现：具有传输量子位的超导电路。
We show that in the mathematical framework of the quantum theory the classical pigeonhole principle can be violated more directly than previously suggested, i.e., in a setting closer to the traditional statement of the principle. We describe how the counterfactual reasoning of the paradox may be operationally grounded in the analysis of the tiny footprints left in the environment by the pigeons. After identifying the drawbacks of recent experiments of the quantum pigeonhole effect, we argue that a definitive experimental violation of the pigeonhole principle is still needed and propose such an implementation using modern quantum computing hardware: a superconducting circuit with transmon qubits.
