MicroCloud Hologram Inc. Revolutionizes Quantum Computing with DAQC

MicroCloud Hologram Inc. (HOLO) has made waves in the tech industry with the launch of its groundbreaking Digital Analog Quantum Computing (DAQC) paradigm. This innovative approach combines the best of digital and analog quantum computing, paving the way for more efficient and accurate quantum algorithms on real hardware. Let's dive into the details of this exciting development and explore its implications for the future of quantum computing.



DAQC is a hybrid approach that leverages the strengths of both digital and analog quantum computing. By cleverly combining these two methods, HOLO has developed an efficient digital simulated quantum algorithm specifically designed for calculating the Quantum Fourier Transform (QFT). This subroutine is widely used in various quantum algorithms, making its improvement crucial for the overall development of the quantum algorithm framework.

HOLO's research has shown that as the number of quantum bits involved gradually increases, the fidelity of the QFT performed using this digital simulated quantum algorithm can be significantly improved. This achievement is attributed to HOLO's thorough exploration of algorithm development and the effective application of the DAQC paradigm.

During the research process, HOLO selected the homogeneous all-to-all (ATA) two-body Ising model as the foundational resource for implementing DAQC. The Hamiltonian of this model was further represented as a non-homogeneous ATA two-body Ising model, establishing a solid theoretical framework for the efficient implementation of the algorithm.

To validate the effectiveness and superiority of the algorithm, HOLO conducted extensive numerical simulation experiments on quantum devices with 3, 5, 6, and 7 qubits. The test results clearly demonstrated that the fidelity between the ideal transformation and the transformation achieved by DAQC improves significantly as the number of qubits increases, outperforming the fidelity provided by purely digital implementations in terms of quality.



HOLO's fast adiabatic driving protocol is another key component of their DAQC approach. This protocol leverages the quantum adiabatic theorem for precise energy control in a double quantum dot system. By meticulously designing control paths based on adiabatic evolution rules, it guides heavy hole spin qubits along predefined trajectories, ensuring high-fidelity quantum state transitions while avoiding distortions from abrupt energy changes or external disturbances.

This approach is similar to precise navigation in interstellar travel, ensuring accurate quantum state transitions by carefully managing energy variations within the quantum system. As a result, HOLO's fast adiabatic driving protocol achieves higher quantum state fidelity compared to traditional protocols, delivering superior performance in quantum information processing.



In conclusion, MicroCloud Hologram Inc.'s DAQC paradigm represents a significant breakthrough in addressing quantum computing's noise challenges. By combining the flexibility of digital quantum computing with the robustness of simulated quantum simulation, HOLO has developed an efficient digital simulated quantum algorithm that improves the fidelity of the Quantum Fourier Transform as the number of qubits increases. This achievement, along with the successful implementation of the homogeneous all-to-all Ising model and the fast adiabatic driving protocol, paves the way for more efficient and accurate quantum algorithms on real hardware. As the technology continues to evolve, DAQC has the potential to become a crucial component in achieving "useful quantum supremacy" in the field of quantum computing.
