Tencent Announces Latest Research Progress in Quantum Computer Architecture, Exploring Highly Parallel Architectures
A novel quantum control microarchitecture, QuAPE, has been proposed by a team at Tencent’s Quantum Laboratory. Experiments show that a 2.59-fold speedup (up to 3.11-fold theoretically) was achieved in a test of a complex algorithm with large amounts of feedback through a multicore architecture; an average 4.04-fold performance improvement was achieved in a test of several other common quantum algorithms through a superscalar architecture. The new highly parallel control method provides an important foundation for building a control layer suitable for large-scale quantum computers.
ZTE and CAS Quantum Net jointly build quantum security applications
At the 2021 China Smart City Expo, ZTE and CAS Quantum Net have partnered to build quantum security applications to build an ICT infrastructure industry that incorporates QKD technology. The project has reportedly landed in Chongqing and has built a quantum security-based cloud computing platform for the local government to unify and securely supervise the data of business systems on the cloud and provide security protection for the data.
