Shenzhen, China, 31 March 2026 /PRNewswire/ — MicroCloud Hologram Inc. (NASDAQ: HOLO), (“HOLO” or the “Company”), a technology services provider, launched an independently developed FPGA-based hardware abstraction technology platform for quantum computing systems. This platform employs a resource-efficient quantum circuit abstraction method, capable of simulating qubit storage, measurement, and phase-shift operations on an FPGA, and building basic quantum state logic units in a non-programmable manner.
After extensive research on quantum state storage modes, mathematical descriptions of quantum gates, probability measurement processes, and the underlying logic structure of FPGA, the HOLO R&D team proposed a resource-efficient quantum circuit hardware abstraction architecture. This architecture does not attempt to fully simulate large-scale quantum systems, but rather starts from the three core features of quantum computing—state storage, phase-shift control, and probability measurement—and transforms them into hardware modules that can be implemented directly within an FPGA layout. The main goal of this concept is to build a lightweight, stable, and scalable hardware abstraction layer, which provides the fundamental structure for future quantum algorithm hardware acceleration, quantum control systems, and quantum embedded devices.
The HOLO R&D team first transformed the state representation of a single qubit from a purely mathematical description into a vectorized structure suitable for FPGA storage and logic operations. A qubit can generally be described by a vector of complex dimensions, i.e., |ψ⟩ = α|0⟩ + β|1⟩, where α and β are complex numbers satisfying |α|² + |β|² = 1. Storing complex numbers directly in the FPGA can lead to high resource consumption; Therefore, the team chose a fixed-point, generalized vector storage scheme that maps complex dimensions into LUT groups and register banks with the smallest resource footprint. This approach significantly reduces FPGA resource usage and ensures stable storage of qubits in low-resource environments.
In terms of quantum state development, HOLO does not adopt the full matrix multiplication method to implement quantum gate operations, but instead decomposes general quantum gates (including Pauli-X, Hadamard, RZ phase-shift gates, etc.) into logic operations, which can be directly executed by FPGAs as combinational logic units. This decomposition method makes it possible to simulate single-qubit and small-scale multi-qubit operations while avoiding extremely high computational resource overhead, thereby better meeting the energy-efficiency requirements of embedded systems.
In the simulation of quantum systems, quantum gates based on phase shift are a key component of quantum computing. Unlike other Boolean logic, phase-shift gates change the phase of the quantum state amplitude rather than flipping or superposing binary values. Therefore, mapping phase-shift logic to an FPGA is an extremely challenging engineering problem.
The HOLO R&D team adopted a lookup-table (LUT)-based phase rotation accumulation method. When qubits are stored as fixed-point complex numbers, phase-shift operations can be understood as rotational transformations of the real and imaginary parts. The team pre-quantized and stored the sine and cosine values required for rotation in FPGA ROM or BRAM and implemented a simplified structure for complex multiplication through combinational logic. To further reduce resource consumption, algorithm engineers employed the CORDIC (Coordinate Rotation Digital Computer) method, using a series of changes and additions to simulate the rotation, enabling the circuit to calculate phase changes within a small area. This solution not only achieves hardware-level phase-shift operation, but also gives high real-time performance and controllability to the entire quantum gate operation.
During the design process, HOLO particularly emphasized the flexibility of the abstraction layer architecture. The system allows dynamic trade-offs between resource consumption and simulation accuracy. For example, the fixed-point quantization precision can be adjusted to meet the error requirements of different quantum gate operations; The stage storage table can be expanded according to work requirements; The randomness of the measurement module can be provided by different seeds and random sources to adapt to different application scenarios.
The FPGA-based quantum computing system hardware abstraction technology released by HOLO this time enables key functions such as quantum state storage, phase regulation, and probability measurement to be realized in a low-power, highly stable hardware logic way for the first time, bringing new engineering possibilities to the entire quantum technology ecosystem. This is expected to promote the integrated development of quantum computing and traditional electronic engineering and accelerate the industrialization of quantum information technology.
