MicroCloud Hologram Inc. Proposes a New Theory of Wasserstein Distance Extended to Quantum States, Supporting Quantum Technology Innovation

SHENZHEN, China, Jan. 23, 2025 /PRNewswire/ — MicroCloud Hologram Inc. (NASDAQ: HOLO), (“HOLO” or the “Company”), a technology service provider, have proposed a novel theory of Wasserstein distance extended to quantum states, which provides a fresh perspective and powerful tools for the research and analysis of quantum states.

Wasserstein distance is a fundamental metric in classical probability distributions, defined based on the minimization of transport costs. It measures the minimal cost required to transform one probability distribution into another. HOLO has innovatively extended this concept to the domain of quantum states. In the quantum world, the description and manipulation of quantum states are far more complex than classical probability distributions, and HOLO’s approach is undoubtedly a significant innovation.

HOLO reveals a natural correspondence between the transport plans of quantum states and quantum channels. This means that in quantum systems, the transport process can be precisely interpreted as a physical operation on the system. The discovery of this correspondence provides a more intuitive and accurate understanding of quantum information transmission and processing. In traditional quantum research, the transmission of quantum information is often viewed as an abstract process, but HOLO analyzes and grasps this process from the perspective of physical operations, laying a theoretical foundation for further optimization of applications such as quantum communication and quantum computing.

HOLO’s main research focuses on the proof of the modified triangle inequality. In both mathematics and physics, the triangle inequality is a fundamental relational inequality that plays a crucial role in many theories and applications. For the Wasserstein distance extended to quantum states, HOLO has derived and proven the modified triangle inequality through rigorous theoretical derivation. The validity of this inequality not only enriches the theoretical framework of quantum state Wasserstein distance but also has significant practical implications. For example, in the design of quantum error-correcting codes, this modified triangle inequality can be used to more accurately assess errors and distortions in quantum information during transmission, thus enabling the design of more efficient and reliable quantum error correction schemes.

Additionally, HOLO has proven that the distance between a quantum state and itself is closely related to the Wigner-Yanase metric on the quantum state manifold. The quantum state manifold is an important concept for describing the structure of quantum state space, while the Wigner-Yanase metric is a key tool for characterizing the geometric properties of the quantum state manifold. HOLO’s discovery reveals the intrinsic connection between the Wasserstein distance of quantum states and the geometric properties of the quantum state manifold. This connection provides a new approach to studying quantum states from a geometric perspective, aiding in a deeper understanding of the nature and characteristics of quantum states. By exploring the relationship between the distance of a quantum state to itself and the Wigner-Yanase metric, it is possible to further investigate important properties such as the stability and distinguishability of quantum states, thus providing theoretical support for the optimization of quantum information processing and quantum computing.
