MicroCloud Hologram develops quantum transmission scheme

MicroCloud Hologram Inc. (NASDAQ: HOLO) announced it developed a transmission scheme for GHZ states and W states based on Brownian state quantum channels. The technology service provider said the scheme establishes a transmission mechanism for multi-particle entangled states through quantum channels and measurement systems.

The company uses quantum Fourier transform for quantum state projection measurement and designs quantum gate operations for reconstructing quantum states at the receiving end. The Brownian state is a four-particle entangled state that the company uses to establish quantum links for transmission.

In the transmission process, the sender performs joint measurement on the quantum state and specific particles in the Brownian state, establishing quantum correlation between the transmission state and channel state. The receiver selects corresponding quantum gate operations to reconstruct the original quantum state based on measurement results transmitted through the classical channel.

The quantum Fourier transform constructs the measurement framework for projection measurement by mapping quantum states to standard measurement bases. The company said this transformation is realized through quantum logic gates, with system complexity maintaining a relationship with the number of qubits.

For GHZ state transmission, operations include phase gates and controlled-NOT gates. W state transmission requires multi-particle control operations. The company verified the feasibility of quantum gate operations on superconducting quantum processors through electromagnetic control signals of qubits.

The protocol has potential applications in quantum communication, distributed quantum computing, quantum secure communication, and distributed quantum measurement. The company said the scheme could serve as core transmission modules in quantum network architectures for transmitting quantum information between computing nodes.

Based in Shenzhen, China, MicroCloud Hologram provides holographic technology services including LiDAR solutions and holographic imaging. The company reported cash reserves exceeding 3 billion RMB and plans to invest more than $400 million in blockchain development, quantum computing, and artificial intelligence technologies.
