Quantum computing holds immense promise for solving complex problems intractable for classical computers. However, quantum systems are notoriously susceptible to errors, making accurate computations challenging. Quantum error mitigation (QEM) techniques aim to reduce these errors, but current methods often rely on fixed parameters, limiting their effectiveness. This paper proposes a novel approach to QEM utilizing adaptive noise injection, dynamically adjusting the amount of noise based on the observed error profile. We demonstrate that this method significantly improves the accuracy of quantum computations, offering a more robust and adaptable solution compared to existing methods. The system incorporates a continuous error rate monitoring and noise injection mechanism, optimizing for minimal impact on the computation.
Quantum error correction (QEC) is a crucial element in the realization of fault-tolerant quantum computation. However, traditional QEC schemes often rely on pre-determined, static parameters, which may not be optimally suited for the specific noise characteristics present in a given quantum hardware. This work introduces a novel approach to QEC that leverages reinforcement learning (RL) to dynamically adapt the error correction protocol in real-time. The system learns to optimize the parameters of the QEC code, such as measurement schedules and decoding strategies, based on continuous feedback from the quantum hardware. This adaptive approach promises to significantly improve the performance and efficiency of QEC, reducing the overhead associated with error correction and enhancing the fidelity of quantum computations. The core claim of this paper is that quantum error correction is computationally intensive and requires precise control over quantum systems. The central mechanism involves employing reinforcement learning to optimize the parameters of quantum error correction protocols in real-time, adapting to the specific noise characteristics of the quantum hardware. This represents a new automation of the QEC process.
Quantum error mitigation (QEM) is a crucial technique for enhancing the reliability of quantum computations. Current methods, however, often rely on fixed noise levels, which can be computationally demanding and limit efficiency. This paper introduces a novel QEM algorithm utilizing a Bayesian neural network to dynamically adjust the probabilistic noise applied during error correction. Our design systematically learns the optimal noise level for each quantum state, continuously adapting to the evolving error profile. This adaptive approach promises to significantly improve both error suppression and computational efficiency compared to existing methods. The proposed algorithm offers a fundamentally new way to optimize error mitigation, paving the way for more robust and practical quantum computations.
Adaptive quantum computing control is important for the stability and efficiency of quantum systems, especially in the presence of dynamic environmental noise and hardware fluctuations. We present a unified strategy for machine learning (ML) techniques to improve adaptive quantum control in two main directions: optimization speed and out-of-sample error. Here, we propose a hybrid learning method combining reinforcement learning (RL), deep neural networks (DNNs), and quantum-inspired models to actively and adaptively update quantum gate parameters and error mitigation strategies on the fly. Embedding of quantum noise models directly into the learning allows the system to predict and correct for decoherence, gate errors and measurement inaccuracy before they affect computational fidelity. Using extensive simulations as well as experimental validation on noisy intermediate-scale quantum (NISQ) processors, our improved ML model achieves a substantially higher fidelity and robustness compared to standard model-free and static control approaches. We introduce a novel feedback-loop mechanism based on online learning algorithms enabling the system to adjust for changing noise profiles and hardware drift without retraining. The optimization part uses metaheuristic methods to quickly converge to control parameters that perform well, and the error prevention mechanism features anomaly detection and prediction correction layers to minimize the effects of cumulative decoherence. The results demonstrate that our adaptive control framework can be used to not only speed up the convergence in training quantum algorithms, but also sustain the performance of gates against error at a variety of error rates with the reduction of the real-time impact of the error up to 35 %. This work highlights the promise of machine learningaugmented quantum control for improving reliability and scalability in quantum computing and serves as a stepping stone for future incorporation with fault-tolerant designs.
