摘要: 量子博弈论是量子信息和经典博弈论的交叉研究方向。理论研究表明,量子博弈模型不仅能够突破经典博弈模型的收益上限,更是有望用于深入理解和突破量子通信、量子计算等领域的很多基础问题。针对一种利益冲突的贝叶斯量子博弈模型,提出了一种可编程的光量子芯片结构,首次运用硅基光量子芯片实验完成了量子博弈实验。通过动态生成和调控片上量子纠缠态,实验证实了量子博弈相对经典博弈的博弈优势,展示了光量子芯片在量子博弈论研究中的重要作用,为量子信息领域更复杂问题的研究提供了重要的实验手段。

Abstract: Quantum game theory is an interdisciplinary area combining quantum information and game theory. Theoretical studies demonstrate that quantum games surpass the maximal interest of classical ones, which can be applied to analyze and solve fundamental problems in various fields, such as quantum communication and quantum computing. Aiming at a Bayesian quantum game model with conflictive interests, this paper proposes a programmable photonic quantum chip structure, and completes the quantum game experiment with silicon based optical quantum chip for the first time. By dynamically generating and modulating entangled states on the chip, the experiment demonstrates the advantage of the quantum game over the classical one. This paper shows that photonic quantum chips play a vital role in the research of quantum game theory and provide a promising methodology to study more complicated problems in the field of quantum information.
