Quantum compilation is the problem of translating an input quantum circuit into the most efficient equivalent of itself, taking into account the characteristics of the device that will execute the computation. Compilation strategies are composed of sequential passes that perform placement, routing and optimization tasks. Noise-adaptive compilers do take the noise statistics of the device into account, for some or all passes. The noise statistics can be obtained from calibration data, and updated after each device calibration.

Quantum circuit compilation is a fundamental step in quantum computing, translating high-level quantum algorithms into sequences of gates executable on a specific quantum hardware. However, current compilation methods often employ static decompositions, neglecting the inherent noise characteristics of quantum devices, leading to suboptimal circuit designs and reduced fidelity. This work proposes a novel adaptive quantum circuit compilation strategy that dynamically adjusts circuit decompositions in real-time, based on continuous monitoring of hardware noise profiles. The core of this approach lies in integrating quantum error mitigation techniques with a feedback loop that iteratively refines the circuit design to minimize the detrimental effects of noise. We introduce a framework for evaluating the effectiveness of this adaptive compilation process, demonstrating potential improvements in circuit fidelity and execution time. This research directly addresses the critical need for real-time adaptive compilation, a cornerstone for the practical realization of fault-tolerant quantum computing. The presented methodology offers a promising path towards more efficient and robust quantum algorithms, ultimately contributing to the advancement of quantum information processing.
Quantum circuit compilation is a critical step in realizing quantum algorithms on real quantum hardware. Traditional compilation methods often employ static optimization strategies, neglecting the unique constraints and characteristics of the target quantum device. This paper introduces a novel adaptive quantum circuit compilation framework designed to dynamically adjust circuit designs based on hardware-specific information, aiming to minimize gate count and, consequently, error rates. The core of the framework lies in integrating a hardware simulator directly within the compilation process. This allows the compiler to evaluate the performance of various circuit designs—considering factors like qubit connectivity, gate fidelity, and decoherence models—before committing to a final layout.

This paper presents a novel approach to quantum circuit compilation that leverages the feedback capabilities of the Variational Quantum Eigensolver (VQE) to achieve adaptive optimization. Traditional quantum compilation methods are static, assuming a known and consistent noise profile for the target quantum hardware. However, real quantum devices exhibit significant noise variations, leading to suboptimal circuit execution. Our strategy addresses this challenge by dynamically adjusting compilation parameters based on the VQE's error estimations during runtime. The core idea is to implement a real-time optimization loop where the VQE provides error estimates for individual gate operations, and the compiler subsequently modifies the circuit topology and gate choices to minimize overall error. This adaptive compilation scheme allows the quantum circuit to 'learn' the noise characteristics of the hardware, leading to a reduction in gate count and improved fidelity. The presented framework offers a pathway towards more robust and efficient quantum computation, particularly relevant as quantum hardware matures and noise mitigation techniques become more sophisticated. We outline the key components of the system, including the VQE integration, the compilation algorithm, and a discussion of potential challenges and future research directions.
Variational quantum algorithms (VQAs) hold significant promise for solving complex problems across diverse fields. However, their practical implementation on near-term quantum devices is severely hampered by the pervasive effects of quantum noise. Traditional quantum circuit compilation techniques are largely static, failing to account for the unique noise profiles inherent in individual quantum hardware. This paper introduces a novel adaptive quantum circuit compilation framework designed to mitigate these limitations. The core concept centers around dynamically adjusting the circuit layout and gate decomposition in real-time, leveraging measurements of the quantum hardware's noise characteristics to optimize both the accuracy and circuit depth of the compiled quantum circuit. This approach represents a critical step towards unlocking the full potential of VQAs by enabling them to effectively operate within the constraints of noisy quantum computers. The framework incorporates feedback loops for continuous refinement, adapting to evolving noise conditions. The methodology is described, focusing on the key components: noise profiling, adaptive gate decomposition, and circuit re-optimization. Simulation results demonstrate the effectiveness of the adaptive approach in reducing circuit depth and improving the fidelity of VQA computations compared to static compilation methods. This work lays the foundation for robust and efficient VQA execution on future quantum hardware.
