MicroCloud Hologram Inc. Studies Three Quantum Circuit Models to Achieve Cost Optimization of Quantum Channels

Core Insights - MicroCloud Hologram Inc. has conducted research on optimizing quantum channel implementation, focusing on minimizing C-NOT gate counts while ensuring functional correctness [1][3][7] - The company has developed three quantum circuit models: Quantum Circuit Model (QCM), RandomQCM, and MeasuredQCM, each providing different degrees of freedom for circuit design [2][4][5] Quantum Circuit Models - The Quantum Circuit Model (QCM) utilizes a strict sequence of single-qubit and C-NOT gates, ensuring deterministic implementation but with limited operational freedom [2] - RandomQCM introduces classical randomness to allow probabilistic operations, which helps in reducing C-NOT gate counts, especially for probabilistic quantum channels [2][4] - MeasuredQCM incorporates measurement operations and conditional control, enhancing circuit flexibility and enabling simplified decomposition of complex quantum channels [2][4][5] C-NOT Gate Optimization - The research establishes lower bounds on C-NOT gate counts for quantum channel decomposition, influenced by the channel's entanglement capacity and qubit dimensions [3][4] - Near-optimal solutions were found, with C-NOT gate counts controlled within 1.5 times the theoretical lower bound in QCM, 1.2 times in RandomQCM, and approaching the lower bound in MeasuredQCM [4][5] Practical Applications and Challenges - The research provides a new paradigm for quantum circuit design that integrates measurement, classical feedback, and quantum operations, enhancing resource efficiency [5] - Challenges remain in practical applications, such as the need for precise control of measurement timing and high real-time performance from classical control logic [6] Company Overview - MicroCloud Hologram Inc. focuses on holographic technology services, including LiDAR solutions and holographic digital twin technology, and plans to invest over $400 million in quantum computing and related technologies [8][9]
