MicroCloud Hologram proposes quantum state sharing scheme

MicroCloud Hologram Inc. (NASDAQ: HOLO) announced a proposed multi-qubit quantum state sharing scheme that enables collaborative recovery of multiple quantum states among participants through what the company describes as a "one-time distribution + one-time recycle" mechanism.

The scheme uses quantum entanglement encoding combined with single-particle measurement and data collaborative processing. According to the company, the dealer encodes multiple k-qubit states into a hyper-entangled state of particles, utilizing multidimensional properties such as polarization and path of photons. Participants obtain local data through measurements, and the dealer reconstructs the original state using a maximum likelihood estimation algorithm.

The company reports that the technology enables a single photon to carry 3 qubits of information, improving resource efficiency by 3 times compared to traditional methods. The adaptive measurement strategy reduces the number of measurements by 30% and errors to one-fifth of random measurements, according to the announcement.

In testing, the scheme achieved simultaneous sharing of 2 3-qubit GHZ states in a photonic system, reducing the usage of entangled particles by 50% and decreasing classical communication volume by 40%. The system maintained fidelity above 85% even under a 1% channel error rate, the company stated.

MicroCloud acknowledged implementation challenges including automated preparation of high-dimensional entangled states, femtosecond-level timing synchronization precision requirements, and bandwidth limitations of quantum-classical interfaces. The company said future development will focus on solid-state quantum system integration, quantum machine learning optimization algorithms, and metropolitan-scale quantum relay network deployment.

MicroCloud Hologram provides holographic technology services including LiDAR solutions and holographic digital twin technology services. The information is based on a company press release.
