Jiayin Chen, Hendra I. Nurdin, Naoki Yamamoto

摘要:

机器学习和量子计算的结合已经成为解决以前无法解决的问题的一种有前途的方法。水库计算是一种有效的学习范例,其利用非线性动态系统进行时间信息处理,即,处理输入序列以产生输出序列。在这里,我们提出量子水库计算,利用复杂的耗散量子动力学。我们的量子库类是普适的,因为任何非线性衰落记忆映射都可以通过这类量子库在所有输入上任意接近和一致地近似。我们描述了一个子类的通用类,很容易实现使用量子门本地当前的噪声门模型量子计算机。在远程访问的基于云的超导量子计算机上进行的原理验证实验表明,小而嘈杂的量子库可以解决高阶非线性时间任务。我们的理论和实验结果为近期门模型量子计算机的有吸引力的时间处理应用铺平了道路,这些量子计算机具有更高的保真度,但没有量子纠错,这意味着这些设备具有更广泛的应用潜力,包括神经建模,语音识别和自然语言处理,超越静态分类和回归任务。

英文摘要:

The combination of machine learning and quantum computing has emerged as a promising approach for addressing previously untenable problems. Reservoir computing is an efficient learning paradigm that utilizes nonlinear dynamical systems for temporal information processing, i.e., processing of input sequences to produce output sequences. Here we propose quantum reservoir computing that harnesses complex dissipative quantum dynamics. Our class of quantum reservoirs is universal, in that any nonlinear fading memory map can be approximated arbitrarily closely and uniformly over all inputs by a quantum reservoir from this class. We describe a subclass of the universal class that is readily implementable using quantum gates native to current noisy gate-model quantum computers. Proof-of-principle experiments on remotely accessed cloud-based superconducting quantum computers demonstrate that small and noisy quantum reservoirs can tackle high-order nonlinear temporal tasks. Our theoretical and experimental results pave the path for attractive temporal processing applications of near-term gate-model quantum computers of increasing fidelity but without quantum error correction, signifying the potential of these devices for wider applications including neural modeling, speech recognition and natural language processing, going beyond static classification and regression tasks.
