MicroCloud Hologram Inc. (NASDAQ:HOLO) shares rocketed on Monday after the company developed an advanced technological solution. The solution uses a fast adiabatic driving protocol to attain coherent control of two heavy hole spin qubits in a double quantum dot system.
HOLO’s protocol surpasses the limitations of traditional methods like linear ramps, π-pulses, and Landau-Zener channels, delivering superior fidelity in quantum information processing.
The fast adiabatic driving 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.
Similar to interstellar navigation, this method achieves superior quantum state fidelity by precisely managing energy variations within the system.
MicroCloud’s fast quasi-adiabatic driving via spin-orbit coupling achieves two key breakthroughs: suppressing charge noise to stabilize qubit operations and ensuring precise qubit initialization for accurate quantum computations. These advancements create a low-noise, reliable foundation for high-complexity tasks.
MicroCloud has developed and implemented both single-qubit and two-qubit gate operations, specifically NOT, CNOT, and SWAP-like gates. In the heavy-hole spin system architecture within the double quantum dot, these quantum gate operations achieve quantum state fidelities as high as 99%.
