Abstract

Abstract The performance of quantum simulations heavily depends on the efficiency of noise mitigation techniques and error correction algorithms. Reinforcement has emerged as a powerful strategy to enhance the efficiency of learning and optimization algorithms. In this study, we demonstrate that a reinforced quantum dynamics can exhibit significant robustness against interactions with a noisy environment. We study a quantum annealing process in which reinforcement encourages the system to maintain its current state or follow a noise-free evolution. A learning algorithm is used to derive a concise approximation of these reinforced dynamics, thereby reducing the total evolution time and, consequently, the system’s exposure to noisy interactions. This also avoids the complexities associated with implementing quantum feedback in such reinforcement algorithms. The efficacy of our method is demonstrated through numerical simulations of reinforced quantum annealing with one-qubit and two-qubit systems under Pauli noise.

Noise tolerance via reinforcement in the quantum search problem

Marjan Homayouni-Sangari, Abolfazl Ramezanpour

The Grover lower bound for the unstructured search problem can be surpassed when some information about the data structure is available. Here, we numerically observe that reinforcement can exponentially reduce the number of required evolution layers from $\sqrt{D}$ to $\ln D$ in a $D$-dimensional system, by exploiting the information provided by the quantum state. Therefore, a reinforced quantum search is expected to exhibit a larger noise threshold compared to a standard search algorithm in a noisy environment. We use numerical simulations to characterize the level of noise tolerance via reinforcement in the presence of both coherent and incoherent noise, considering a system of $N$ qubits and a single $D$-level (qudit) system. Our results show that reinforcement significantly enhances the algorithm's success probability and improves the scaling of the number of reinforced evolution layers with system size. These findings indicate that reinforcement offers a promising strategy for error mitigation, especially when a precise noise model is unavailable.

Adaptive Quantum Error Correction via Reinforcement Learning

Jincheng Zhang

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.

Enhancement of Machine Learning for Adaptive Quantum Computing Control: The Optimization Performance and Prevention of Real Time Error

V. Saravanan, Ganesan M, R. Balasubramaniyan +3 more

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.

Adaptive Quantum State Collapse Control Algorithm

Jincheng Zhang

This paper presents an adaptive quantum state collapse control algorithm designed to mitigate the detrimental effects of environmental noise on quantum states. The core of the algorithm relies on a reinforcement learning (RL) framework to dynamically adjust control strategies based on real-time feedback from the quantum environment. Specifically, a controller is constructed utilizing an RL agent that interacts with the quantum system, learning an optimal control policy to minimize state collapse. A key element is the integration of quantum decoherence techniques to reduce the impact of noise. The algorithm's adaptive nature allows it to contend with fluctuating noise levels, a significant challenge in maintaining the coherence of fragile quantum states. The proposed approach offers a novel method for controlling quantum systems, overcoming the limitations of conventional quantum control methods which often rely on static control parameters. The results demonstrate the efficacy of this dynamic control strategy in preserving quantum state fidelity under varying noise conditions. This work contributes to the development of robust quantum control protocols for applications such as quantum computation and quantum sensing.
