MicroCloud Hologram Inc. proposed a quantum secure tripartite computing protocol based on BQC, effectively filling the gap in the field of multi-client collaborative computing. The tripartite computation involves two quantum-limited clients and a remote quantum server, and this protocol fully leverages the blindness of BQC to establish a robust barrier for protecting client data privacy. During the computation process, clients convert the data to be processed into a specific quantum information form and transmit it to the server through the unique processing method of BQC.
While executing computational tasks, the server can only operate on the quantum information according to a predetermined process, unable to access the specific content of the client’s data, including the meaning of the input data, the actual information corresponding to the output results, and the algorithmic logic employed by the clients. This approach fundamentally addresses the risk of client data privacy leakage in tripartite computation, allowing mutually distrusting clients to confidently engage in collaborative computing with the same server. Furthermore, HOLO has extended the quantum secure tripartite computing protocols into a quantum secure multi-party computing protocol, making its applicability even broader.
In multi-party computing scenarios, the number of clients may exceed two, and the protocol ensures independent privacy protection for each client’s data by optimizing the application of BQC’s blindness. Different clients cannot access each other’s private data due to participating in the same computational task, and the server is also unable to parse the data of any individual client. This extension is not merely about increasing the number of clients but involves systematic adjustments to data transmission paths and server processing workflows while maintaining the protocol’s security.
These adjustments enable the protocol to stably and efficiently support multi-client collaborative computing, meeting the demands of a wider range of practical application scenarios. HOLO’s quantum secure multi-party computing protocols based on BQC not only addresses the current issues of data privacy and process complexity in multi-client collaborative computing but also lays the foundation for the practical application of quantum computing in more fields. In the future, as quantum technology continues to advance, the protocol has room for further optimization, such as improvements in handling a larger number of clients and processing more complex computational tasks.
This will continue to inject new momentum into the development of quantum secure multi-party computing, driving the entire quantum computing field toward a more secure, efficient, and practical direction.
