BEIJING, Jan. 31, 2025 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WiMi) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of an FPGA (Field-Programmable Gate Array)-based digital quantum computer verification technology, an innovative advancement that takes quantum computing to new heights.

WiMi has developed a new computing model, the "digital quantum computer," in which quantum bits (qubits) are treated as discrete entities — finite state machines (FSMs), referred to as "digital qubits." Digital qubits are operated on by specific digital quantum gates, whose behavior is similar to logic gates in classical computing, but with a design more closely aligned with the principles of quantum mechanics. WiMi's digital qubits represent and manipulate quantum states in digital form, allowing them to be validated and implemented through traditional digital circuits.

FPGA, as a flexible hardware architecture, offers the capability of dynamic reconfiguration, making it an ideal platform for the implementation and verification of digital qubits. By implementing digital quantum gate chains in FPGA, it is possible to simulate and validate quantum computing behavior within a classical computing architecture. This approach not only provides repeatability and reliability but also significantly reduces the complexity and cost of hardware implementation.

WiMi has designed a prototype of digital qubits on FPGA, describing the transformation rules of their quantum states using Hardware Description Language (HDL). These quantum states are discretized into different digital states, and digital quantum gates are responsible for converting between these states. For example, a simple Hadamard gate chain was implemented on FPGA to simulate the state transition of qubits. This design validates the feasibility of the FPGA-based digital quantum computing model.

The digital quantum gate chain is a core component of WiMi's digital quantum computer. By implementing these gate chains on FPGA, key operations in various quantum algorithms are simulated. For example, in the simulation of Shor's algorithm, WiMi implemented a set of digital quantum gate chains that control non-trivial states. These gate chains are distributed across multiple logic units in the FPGA and enhance computational efficiency through parallel processing and pipelining techniques. Additionally, a FPGA-based verification platform is used to validate the digital quantum computer. On this platform, the behavior of digital qubits can be monitored in real-time, and interaction with classical computing systems is possible via external interfaces. This platform not only demonstrates the theoretical and simulation consistency of the digital quantum computer but also verifies its operability on actual hardware.
