摘要:

近年来,近场噪声中间尺度量子(NISQ)计算设备已经变得可用。利用这种NISQ量子计算机原型的最有前途的应用领域之一是量子机器学习。虽然量子神经网络被广泛研究用于监督学习,但量子强化学习仍然只是该领域的一个新兴领域。为了解决经典的连续控制问题,我们使用连续变量量子机器学习方法。我们介绍了光子变分量子代理的邻近策略优化,并研究了数据重新上传的影响。我们通过使用Strawberry Fields,光子模拟器Fock后端和连接到OpenAI Gym环境和TensorFlow的混合训练框架的实证研究来进行性能评估。对于受限CartPole问题,光子策略学习的两种变化实现了可比的性能水平和比相同数量的可训练参数的基线经典神经网络更快的收敛。

英文摘要:

In recent years, near-term noisy intermediate scale quantum (NISQ) computing devices have become available. One of the most promising application areas to leverage such NISQ quantum computer prototypes is quantum machine learning. While quantum neural networks are widely studied for supervised learning, quantum reinforcement learning is still just an emerging field of this area. To solve a classical continuous control problem, we use a continuous-variable quantum machine learning approach. We introduce proximal policy optimization for photonic variational quantum agents and also study the effect of the data re-uploading. We present performance assessment via empirical study using Strawberry Fields, a photonic simulator Fock backend and a hybrid training framework connected to an OpenAI Gym environment and TensorFlow. For the restricted CartPole problem, the two variations of the photonic policy learning achieve comparable performance levels and a faster convergence than the baseline classical neural network of same number of trainable parameters.
