Bayesian Optimization (BO) has emerged as a powerful technique for optimizing black-box functions, particularly in scenarios where evaluations are expensive. However, traditional BO often suffers from inefficient exploration due to the reliance on a fixed, uniform prior distribution. This paper proposes a novel Bayesian Optimization framework, termed Quantum-Inspired Bayesian Optimization with Adaptive Entanglement (QIBOA), which draws inspiration from quantum mechanics, specifically the concept of adaptive entanglement, to dynamically adjust the prior distribution. The core idea is to represent the prior distribution using entangled states, where the entanglement strength is adaptively modified based on the observed function values. Higher entanglement indicates greater uncertainty and encourages exploration, while lower entanglement signifies higher confidence and promotes exploitation. The adaptive nature of this entanglement allows QIBOA to effectively balance exploration and exploitation, leading to improved optimization performance. We demonstrate the effectiveness of QIBOA through theoretical analysis and illustrate its advantages with simulations against established BO algorithms. The key contributions of this work include a new exploration strategy rooted in quantum-inspired concepts and a framework for dynamically adapting the prior distribution in Bayesian Optimization.

Bayesian Optimization (BO) has emerged as a powerful technique for optimizing black-box functions, particularly in scenarios with expensive evaluations. However, its performance often degrades in high-dimensional spaces due to the curse of dimensionality, leading to inefficient exploration of the search landscape. This work proposes a novel approach to BO that leverages the principles of quantum mechanics, specifically entanglement, to accelerate the optimization process. We introduce a framework where candidate solutions are represented as entangled quantum states. This representation inherently captures correlations between different parts of the search space, enabling a more focused and efficient exploration strategy. The core mechanism involves evaluating the objective function for these entangled states, allowing the algorithm to exploit the natural correlations. We demonstrate the efficacy of this quantum-inspired BO method through theoretical analysis and a conceptual illustration, showcasing its potential to outperform traditional BO methods in high-dimensional problems. The key innovation lies in translating the concept of quantum entanglement into a classical optimization framework, offering a fundamentally different approach to exploration and potentially unlocking significant performance gains.
Bayesian Optimization (BO) is a powerful technique for optimizing black-box functions, particularly effective in scenarios with expensive evaluations. However, its performance often degrades significantly in high-dimensional search spaces, a phenomenon known as the "curse of dimensionality." This paper introduces a novel Bayesian Optimization framework termed Quantum-Inspired Bayesian Optimization (QIBO) that addresses this limitation by leveraging concepts from quantum mechanics, specifically entanglement, to structure the search space. QIBO models the search space as an entangled quantum system, where updates to individual parameters are constrained through Bell inequality-inspired mechanisms. This promotes correlated exploration and exploitation, leading to potentially faster convergence and improved performance compared to traditional BO. We formulate the optimization problem as a quantum state evolution governed by the Bell inequalities, and demonstrate its efficacy through theoretical analysis and conceptual examples, highlighting the potential for QIBO to overcome the challenges posed by high-dimensional search spaces. The key contribution lies in the strategic introduction of entanglement to guide the search process, moving beyond purely independent updates often found in standard BO.
Bayesian optimization has emerged as a powerful technique for tackling high-dimensional black-box optimization problems. However, its performance often degrades significantly when the dimensionality of the search space increases, a phenomenon known as the "curse of dimensionality." This paper proposes a novel approach – Quantum-Inspired Bayesian Optimization – that addresses this limitation by incorporating principles inspired by quantum computing, specifically quantum annealing. The core idea is to utilize a modified version of quantum annealing to guide the acquisition of function evaluations, exploiting superposition and interference to enhance exploration in high-dimensional spaces. We formulate the optimization problem as a quantum-inspired search, where candidate solutions exist in a superposition of states and are refined through interference effects. The algorithm iteratively updates the probability distribution over the search space, favoring regions with high potential based on the quantum-inspired exploration strategy.

The theoretical analysis suggests a potential improvement in the exploration efficiency, particularly in high-dimensional search spaces. The algorithm's adaptability allows it to overcome challenges often encountered in BO, such as the "curse of dimensionality," leading to improved performance across a range of optimization problems. The method's effectiveness is demonstrated through a conceptual framework and analytical discussion, highlighting the key components and their interactions.
Bayesian inference, a cornerstone of statistical modeling, often struggles with the complexities of high-dimensional data and non-Gaussian distributions commonly encountered in complex systems. This paper proposes a novel approach termed Quantum-Inspired Bayesian Inference (QIBI), leveraging concepts from quantum mechanics – specifically superposition and entanglement – to enhance the efficiency and accuracy of Bayesian inference. QIBI represents prior distributions as superposition states and employs entangled quantum-like circuits to perform marginalization and posterior calculation, effectively addressing the computational bottlenecks associated with traditional methods. We demonstrate the potential of this approach to significantly improve inference performance in scenarios where classical Bayesian methods face limitations. The core of this work lies in the conceptual mapping of Bayesian calculations onto a quantum-inspired framework, providing a new perspective on statistical inference. We define key mathematical formulations to illustrate the proposed methodology, including the superposition state representation of prior distributions and the entanglement-based circuit design for posterior calculation. This exploration aims to bridge the gap between statistical inference and quantum computing, opening avenues for tackling previously intractable problems.

The core idea is to utilize concepts like superposition and entanglement to enhance the efficiency and robustness of Bayesian inference, particularly within dynamic systems where parameters are not static. We represent parameter distributions as quantum state vectors, enabling simultaneous probabilistic consideration of multiple parameter values via superposition. Furthermore, we model entanglement through correlated parameter updates, reflecting the interconnectedness of variables in the system. This approach offers a potentially more effective method for handling uncertainty and evolving parameter spaces compared to traditional classical Bayesian methods. The methodology presented provides a theoretical foundation and a novel approach to Bayesian inference, potentially leading to improved performance in a range of applications, including control systems, time series analysis, and statistical modeling. We demonstrate the underlying principles and formulate the key equations, highlighting the advantages of this quantum-inspired perspective. The framework is intended as a starting point for future research and development in this area.
