MicroCloud Hologram Inc. (NASDAQ: HOLO), shares had sizable gains Friday. The Shenzhen, China-based company, a technology service provider, conducted in-depth research on the low-cost implementation of quantum channels, revealing the optimization boundaries of C-NOT gate counts by constructing a multi-model quantum circuit framework, providing theoretical support for efficient quantum channel design.
The circuit decomposition of quantum channels is the process of transforming abstract quantum state transformations into specific quantum gate sequences, with the core challenge being to minimize the number of C-NOT gates used while ensuring functional correctness. The three quantum circuit models (QCM, RandomQCM, MeasuredQCM) proposed by HOLO build a hierarchical research framework from the perspective of progressively expanding operational degrees of freedom.
The first model is the Quantum Circuit Model (QCM), whose basic structure consists of an ordered sequence of single-qubit gates and C-NOT gates, allowing qubits to be reordered at the end of the gate sequence. This model ensures the deterministic implementation of quantum channels through strict gate operation sequences and qubit routing, but its degree of freedom is limited, relying solely on internal quantum state evolution to complete transformations.
The second model introduces external classical randomness based on QCM, allowing probabilistic operations in the gate sequence design—for example, controlling the selection of certain gates or qubit routing through classical random numbers.
“This extension,” to quote this morning’s news release, “provides new degrees of freedom for reducing C-NOT gate counts, particularly demonstrating advantages in handling probabilistic quantum channels.”
HOLO shares jumped 17 cents, or 3.2%, to $5.45.
