DENVER, Colo., Dec 30, 2024 (247marketnews.com)- MicroCloud Hologram (NASDAQ: HOLO) reportedly developed a fast adiabatic driving protocol to achieve coherent control of two heavy hole spin qubits in a double quantum dot (QD) system.
The Company’s announcement stated, “The fast adiabatic driving protocol is essentially a precise energy control paradigm based on the quantum adiabatic theorem. In the context of a complex double quantum dot (QD) system, it carefully designs control paths according to the system’s adiabatic evolution rules, guiding the two heavy hole spin qubits along predefined trajectories with high-precision quantum state fidelity to achieve state transitions. This approach cleverly avoids the risk of quantum state distortions caused by abrupt energy changes or external disturbances. Similar to the precise navigation in interstellar travel, this control mode ensures accurate quantum state transitions by meticulously managing the energy variations in the quantum system, thereby achieving higher quantum state fidelity compared to traditional protocols.
“From the perspective of practical application efficiency, the implementation of fast quasi-adiabatic driving through spin-orbit coupling mechanisms results in two significant technological outcomes. On one hand, charge noise in the qubit operation process is deeply suppressed. Charge noise has long been a troublesome issue in the field of quantum control, acting like an “invisible interference factor” hidden in the microscopic world. It disturbs the stable state of qubits with subtle and continuous fluctuations, frequently causing computational errors. HOLO’s innovative technological approach serves as a solid “electromagnetic shielding barrier” for qubits, optimizing the electrical environment of the quantum system to effectively block the infiltration of charge noise, ensuring that qubits operate stably in a relatively “low-noise” environment. On the other hand, it achieves high stability in qubit initialization. As the crucial starting point for quantum computation, the stability of initialization plays a decisive role in the accuracy of subsequent full-round computations. High stability means that even when facing external uncertainties such as temperature fluctuations and weak electromagnetic interference, qubits can consistently return to their initial set state with precision, laying a solid foundation for performing high-complexity and high-precision quantum computing tasks.”
