MicroCloud Hologram Inc. introduced a transmission protocol for three-particle GHZ states and W states by constructing a four-particle Brownian state quantum channel. This scheme establishes entanglement correlations through joint measurements and relays classical measurement outcomes to guide reconstruction at the receiver.

The company employs quantum Fourier transform for projection measurement, mapping quantum states onto standard bases via a sequence of quantum logic gates. Specific phase and controlled-NOT gates have been precisely designed for GHZ state reconstruction, while more complex multi-particle control operations handle W states.

HOLO’s research team verified the feasibility of the scheme on superconducting quantum processors. By fine-tuning electromagnetic control signals, they demonstrated reliable execution of the required quantum gate sequences, ensuring the protocol’s scalability on emerging quantum hardware.

This transmission scheme offers potential for distributed quantum computing networks, secure quantum communication, and large-scale quantum information systems. With over RMB 3 billion cash reserves and planned investment of USD 400 million in frontier technologies, HOLO aims to leverage this protocol for practical quantum communication solutions.
