Quantum computers represent a radical technological advancement in the way information is processed by using the principles of quantum mechanics to solve very complex problems that exceed the capabilities of classical systems. However, in the current NISQ era (Noisy Intermediate-Scale Quantum devices), the available hardware presents several limitations, such as a limited number of qubits, high error rates, and reduced coherence times. Efficient management of quantum resources, both physical (qubits, error rates, connectivity) and logical (quantum gates, algorithms, error correction), becomes particularly relevant in the design and deployment of quantum algorithms. In this work, we analyze the role of resources in the various uses of NISQ devices today, identifying their relevance and implications for software engineering focused on the use of quantum computers. We propose a vision for runtime-aware quantum software development, identifying key challenges to its realization, such as limited introspection capabilities and temporal constraints in current platforms. As a proof of concept, we introduce Qonscious, a prototype framework that enables conditional execution of quantum programs based on dynamic resource evaluation. With this contribution, we aim to strengthen the field of Quantum Resource Estimation (QRE) and move towards the development of scalable, reliable, and resource-aware quantum software.
This paper presents a novel approach to resource allocation and scheduling within quantum computing environments. Recognizing the inherent scarcity and unique characteristics of quantum resources, such as qubits and quantum gates, we propose a dynamic algorithm designed to optimize resource utilization and consequently enhance computational efficiency. The core of the algorithm lies in a mechanism that intelligently balances the demands of diverse quantum computing tasks. We formalize this approach using mathematical notation, detailing the key components including task prioritization, qubit assignment, gate scheduling, and dynamic adjustment based on real-time system metrics. The proposed algorithm addresses limitations within existing static scheduling methods, offering improved performance in complex quantum workflows. The design incorporates a queuing theory-inspired model to manage task flow and a stochastic optimization technique for adaptive resource allocation. Simulation results (presented conceptually here) demonstrate the algorithm's potential to significantly improve quantum computing performance compared to traditional approaches. Further research will focus on formal verification and optimization for specific quantum computing architectures.
Noisy Intermediate-Scale Quantum (NISQ) devices are promising platforms for practical quantum computing, but their performance is significantly affected by limited qubit availability, gate errors, decoherence, circuit depth, and hardware-dependent noise. Conventional quantum circuits are generally designed and optimized before execution and may not respond effectively to changing hardware conditions during computation. This research proposes a Self-Adaptive Quantum Circuit framework that dynamically modifies quantum circuits according to the current computational resources and noise characteristics of NISQ devices. The proposed framework monitors parameters such as qubit fidelity, gate error rates, circuit depth, execution time, and resource availability, and automatically selects suitable circuit configurations to improve computational performance. Adaptive mechanisms can be employed to reduce unnecessary gates, optimize qubit utilization, and mitigate the impact of hardware noise while maintaining the required computational accuracy. The framework will be evaluated using simulation platforms and available NISQ quantum hardware, comparing adaptive circuits with conventional static circuits using metrics such as accuracy, fidelity, circuit depth, gate count, execution time, and error rate. The expected outcome is a resource-efficient and noise-aware quantum circuit optimization approach capable of improving the reliability and performance of quantum applications on near-term quantum hardware. The proposed research aims to contribute toward more practical, flexible, and hardware-aware quantum computing systems for NISQ-era applications.

This paper presents a novel adaptive parallel algorithm scheduler designed to optimize the execution of quantum algorithms on imperfect quantum hardware. The core idea leverages quantum degradation analysis to dynamically adjust the scheduling of tasks and resource allocation. Traditional parallel algorithm schedulers often operate under the assumption of ideal quantum hardware, failing to account for the inherent noise and errors present in real-world quantum devices. Our approach utilizes real-time monitoring of quantum hardware degradation, specifically focusing on metrics like single-qubit fidelity, to guide the scheduling process. The scheduler employs a feedback loop, continuously assessing hardware performance and adapting the algorithm execution order and resource assignment accordingly. This adaptive strategy aims to mitigate the impact of quantum noise and maximize the overall fidelity of the final computation. The theoretical framework is presented, and the underlying mathematical concepts are detailed. The effectiveness of the proposed scheduler is illustrated through a conceptual model, showcasing its ability to improve performance in the presence of varying levels of quantum degradation. The primary contribution lies in the integration of quantum degradation analysis directly into the scheduling process, leading to a more robust and efficient execution of parallel quantum algorithms.
The burgeoning field of quantum computing hinges on the efficient execution of quantum algorithms. However, realizing this potential necessitates overcoming significant challenges related to hardware heterogeneity. Current quantum hardware comprises a diverse range of platforms, each possessing unique characteristics – varying qubit connectivity, gate fidelities, and coherence times. A naive approach to scheduling quantum algorithms across these platforms will likely result in suboptimal performance due to the inherent limitations of each device. This work proposes a novel resource-aware scheduling algorithm designed to mitigate these issues. The algorithm dynamically analyzes both the available resources of a quantum hardware platform and the specific algorithmic requirements of a given quantum algorithm. The core of the algorithm involves a cost function that balances resource utilization with algorithmic performance, guiding the selection of the most suitable hardware platform and execution strategy. This approach represents a step towards a more practical and efficient deployment of quantum algorithms, paving the way for leveraging the strengths of diverse quantum computing architectures. The presented method offers a framework for optimizing quantum computation, acknowledging the complex interplay between hardware and algorithm.
