MicroCloud Hologram Inc. (NASDAQ: HOLO) announces a revolutionary technological advancement in the field of quantum computing. The company has developed a rapid adiabatic driving protocol that enables coherent control of two heavy-hole spin qubits in a double quantum dot (QD) system, marking a new milestone in the evolution of quantum technology.
An Innovation Beyond Conventional Protocols
Traditional methods, such as linear ramps and Landau-Zener channels, have allowed incremental advances in quantum control. However, these approaches have physical limitations that hinder achieving the current demands for high fidelity in quantum information processing. The protocol developed by MicroCloud is based on the quantum adiabatic theorem, designing precise control trajectories that ensure state transitions with exceptional quantum fidelity, avoiding distortions caused by abrupt energy changes or external interferences.
This technique not only enhances the fidelity of quantum states but also minimizes charge noise, a critical disruptive factor in quantum systems. This “electromagnetic shield” optimizes the electrical environment, ensuring that qubits operate under stable, low-noise conditions. Furthermore, the protocol guarantees high stability in the initialization of qubits, a key factor for accurately performing complex quantum calculations.
Progress in Quantum Gate Control
MicroCloud has made significant advancements in the implementation of quantum gate operations such as NOT, CNOT, and SWAP, which are fundamental to quantum computing. In the heavy-hole spin system, these operations achieve a quantum state fidelity of over 99%, establishing a new standard in quantum logic gate architecture.
Driving the Future of Quantum Computing
The company will continue to optimize the physical parameters and control processes of its rapid adiabatic driving protocol, exploring new applications and expanding the functional limits of quantum gates. These advancements not only pave the way for practical applications of quantum computing but also strengthen its potential as a driver of innovation in information processing and social development.
