The von Neumann bottleneck and qubit fragility limit scalable computation. This review article synthesizes recent progress in a bio-inspired quantum approach that treats noise, dissipation, and dynamics as resources, drawing from neuroscience, neuromorphic design, and quantum biology. We survey the experimental state of the art: proof‑of‑concept components (tunable couplers and qubit excitations) have been demonstrated across superconducting, semiconducting, and photonic platforms; fully autonomous quantum learning remains theoretical. Near-term strategies harness fixed high-dimensional dynamics with engineered couplers, while long-term visions aim for autonomous, physics-embedded learning. By organizing and critically comparing these developments, we chart the emerging field of quantum neuromorphic computing and identify key challenges and opportunities on the path toward scalable, adaptive quantum processors.

As Moore’s Law approaches its physical limits and traditional deep learning architectures encounter fundamental scaling barriers, the convergence of neuromorphic computing, quantum information processing, and deep learning represents the most promising pathway toward next-generation artificial intelligence systems. Current deep learning approaches, while revolutionary, face critical limitations including exponential energy consumption, limited adaptability, and architectural constraints that prevent true cognitive capabilities. This paper introduces Neuromorphic-Quantum Hybrid Learning (NQHL), a revolutionary computational paradigm that synergistically combines brain-inspired neuromorphic circuits, quantum computational advantages, and deep learning methodologies to create the first truly cognitive artificial intelligence architecture. Our approach addresses four fundamental challenges in next-generation AI: energy-efficient computation through neuromorphic substrates, exponential processing advantages via quantum parallelism, adaptive learning through bio-inspired plasticity mechanisms, and scalable architectures that transcend von Neumann limitations. We develop novel techniques including Quantum Synaptic Networks (QSN), Bio-Inspired Quantum Circuits (BIQC), Hybrid Plasticity Algorithms (HPA), and Neuromorphic-Quantum Interface Protocols (NQIP) that collectively enable AI systems with unprecedented cognitive capabilities. Through comprehensive theoretical analysis and simulation studies, we demonstrate that NQHL achieves 1000x energy efficiency improvements while maintaining 95% accuracy across diverse cognitive tasks including pattern recognition, causal reasoning, and creative problem-solving. Our framework successfully bridges the gap between biological intelligence principles and quantum computational advantages, providing the foundational architecture for post-digital AI systems that can operate at the scale and efficiency required for artificial general intelligence.

Quantum Artificial Intelligence (Quantum AI) embodies the integration of quantum computational paradigms with artificial intelligence frameworks to address the computational intractability and scalability constraints inherent in classical AI systems. By leveraging quantum mechanical properties such as superposition, entanglement, and quantum interference, Quantum AI enables enhanced representation learning, accelerated optimization, and improved probabilistic inference in high-dimensional problem spaces. In parallel, deep-tech innovations—including advanced deep learning architectures, neuromorphic computing, and edge-based intelligent processing—are redefining the architectural foundations of next- generation intelligent systems through energy-efficient, adaptive, and real-time computation. This paper presents a technically rigorous and comprehensive review of Quantum AI and deep-tech innovations, focusing on algorithmic formulations, architectural models, and system-level integration strategies. Core methodologies such as quantum machine learning algorithms, parameterized quantum circuits, variational quantum algorithms, and hybrid quantum–classical optimization frameworks are critically analysed with respect to computational complexity, repressibility, and feasibility on noisy intermediate-scale quantum (NISQ) hardware. Additionally, the role of neuromorphic computing in enabling spiking neural architectures and event-driven processing is examined as a complementary paradigm to quantum-enhanced learning models, particularly for low-power and latency-critical applications. The paper further investigates application- driven deployments of Quantum AI across domains including medical diagnostics, cryptographic security, autonomous decision-making, and smart cyber-physical systems, highlighting performance trade-offs and implementation constraints. Key challenges such as quantum noise, decoherence, data encoding bottlenecks, limited qubit connectivity, and ethical governance are systematically discussed. Finally, future research directions are identified, emphasizing fault-tolerant quantum learning architectures, scalable hybrid integration with deep-tech systems, and co-design methodologies for realizing practical next-generation intelligence platforms.
Digital neuromorphic systems seek to replicate the organizational principles and dynamics of biological neural networks in silicon, offering massive parallelism, event‐driven processing, and orders-of-magnitude lower energy consumption compared with conventional von Neumann computers. Concurrently, quantum artificial intelligence (AI) methods exploit quantum superposition and entanglement to accelerate optimization and pattern-recognition tasks. However, quantum hardware today remains constrained by qubit count and noise, while neuromorphic chips are limited in their ability to discover global optima during training. In this work, we propose and evaluate a hybrid framework—“quantum-optimized neuromorphic inference”—in which a variational quantum circuit (VQC) tunes synaptic weight matrices for a spiking neural network (SNN), and the optimized SNN is deployed on a digital neuromorphic core for inference. We first survey the relevant neuromorphic platforms and quantum machine learning algorithms, then describe our methodology for weight optimization and mapping to neuromorphic hardware. Through extensive simulations on a spoken-digit classification benchmark, our hybrid approach achieves a 3.3% absolute improvement in accuracy over a conventionally trained SNN, while reducing energy per inference by 3.5%. We discuss implications for scalable brain emulation, energy-efficient AI, and future neuromorphic-quantum co-design, and outline next steps toward experimental validation on emerging quantum processors and multi-core neuromorphic systems.

The core idea is to utilize multi-particle quantum entanglement states as the physical connections between artificial neurons, enabling efficient parallel information processing and mimicking biological neural networks. We propose a quantum neuromorphic chip architecture employing multiple superconducting quantum bits (Qubits) engineered to exhibit entanglement. The design focuses on manipulating the coherence time, topological structure, and combined operation of quantum gates to emulate synaptic transmission and learning within biological neural networks. Specifically, we investigate encoding information through entanglement and explore parallel computation facilitated by this quantum phenomenon. Furthermore, we address the challenges of quantum computation by integrating quantum decoherence and quantum error correction techniques. The potential for achieving high-performance, energy-efficient, and biologically inspired computing is discussed, representing a significant departure from traditional approaches and classical neural networks. The proposed framework offers a pathway towards scalable quantum neuromorphic systems with potential applications in areas such as pattern recognition, machine learning, and complex system modeling.
