物理熵驱动的真随机数发生器对新兴概率计算范式至关重要，但传统基于磁隧道结的实现方案受限于固有权衡与弱可调性，已达到性能瓶颈。本文提出利用多铁材料姊妹分支——自铁磁体（Autferroics）构建真随机数发生器。得益于强跷跷板式磁电效应带来的独特能量景观，自铁磁隧道结的真随机数生成性能可显著提升，已通过标准统计测试验证。此外，基于自铁磁体的随机数发生器具备多场可调性与本征多态随机性，为随机电路中复数运算的高效硬件实现及量子混合态概率分布的模拟开辟了新途径。
英文摘要
Physical entropy-driven true random number generators are essential for emerging probabilistic computing paradigms, but conventional implementations based on magnetic tunneling junctions have reached their performance plateaus limited by inherent tradeoffs and weak tunability. Here, autferroics, a sister branch of multiferroics, is proposed to construct true random number generators. Benefiting from its unique energy landscape due to strong seesaw-type magnetoelectricity, the performance of true random number generation can be significantly enhanced in autferroic tunneling junctions, verified by passing standard statistical tests. Furthermore, autferroics-based random number generators can exhibit multi-field tunability and intrinsic multi-state randomness, opening an avenue for efficient hardware realization of the complex-number arithmetic and simulation of probability distributions of quantum mixed states within stochastic circuits.
