The quantum processor is named Qian Shi and implements 10 qubits using superconducting technology. They also indicated they are working on their next generation 36 qubit machine which will use tunable couplers for better isolation, cross-talk resistance and higher gate fidelities. To provide access to this and other quantum processors, Baidu also announced a cloud-based quantum operating environment called Liang Xi. Liang Xi includes a large collection of software modules including Quantum Leaf for providing quantum cloud access, Quanise for quantum control, QEP which is a quantum error correction toolkit, Paddle Quantum for quantum machine learning, and QNET which is a quantum networking toolkit. Interestingly, the Liang Xi platform is also able to provide an interface to other quantum processors in much the same way that Amazon Braket and Microsoft Azure can provide interfaces to several different quantum processors. The first outside processor they are supporting is a trapped ion quantum device developed by the Chinese Academy of Sciences. Baidu has been working on quantum technology for over four years now and has already made 200 core patent applications on this technology. Additional information about Baidu’s quantum announcement can be found in a press release that can be accessed here as well as a webpage for Baidu’s quantum activities available here.
