MicroCloud Hologram Inc. (NASDAQ:HOLO) shares climbed 4.8% in Friday premarket trading following the company's announcement of a new transmission scheme for multi-particle entangled states that leverages Brownian state quantum channels.
According to the company, the approach sets up an efficient mechanism to transmit three-particle GHZ states and W states by constructing tailored quantum channels together with specific measurement systems. The design uses the quantum Fourier transform to carry out quantum state projection measurement, and it incorporates a set of dedicated quantum gate operations intended to reconstruct the transmitted quantum states at the receiver.
Central to the protocol is the Brownian state - described by the company as a particular four-particle entangled state - which serves as the channel to form stable quantum links. In the case of three-particle GHZ state transmission, MicroCloud Hologram said the sender conducts a joint measurement on the transmission state and selected particles of the Brownian state. That joint measurement, the company explained, creates the quantum correlation between the transmission state and the channel state that is necessary for successful transfer.
The company framed the scheme as an enhancement to the theoretical framework of quantum teleportation and as a potential new route for moving information through large-scale quantum systems. MicroCloud Hologram reported that the protocol's feasibility has been verified on superconducting quantum processors.
MicroCloud Hologram also emphasized possible practical applications for the technique within quantum communication. The company said the method could underpin core transmission modules for distributed quantum computing architectures and enable the movement of quantum information among different computing nodes. Additional avenues the company is exploring include quantum secure communication and distributed quantum measurement.
Context and implications
While the announcement focuses on a technical transmission protocol and on-chip verification, the company positioned the development as relevant to efforts in distributed quantum computing and secure quantum links between nodes. The firm pointed to the Brownian-state-based channel and the specified measurement-plus-gate workflow as the operational core of the scheme.
The stock move in premarket trading followed the publication of the details by the company, reflecting investor attention to advances in quantum transmission methods and their potential role in scalable quantum systems.
