US EditionChinese scientists create super stable building block for quantum computers
Using a 6×6 qubit grid on the Zuchongzhi 2 quantum processor, the team demonstrated topologically protected corner states that resist errors, advancing quantum computing reliability.
- Chinese physicist Pan Jianwei and his team created a "quantum Lego block" that stays stable under disturbance, marking a significant advancement in quantum computing technology.
- This research represents the first experimental realization of non-equilibrium higher-order topological phases on a programmable quantum processor, which could improve quantum computing reliability.
- The protected corner states exist in a controlled environment and are not yet fully error-proof, indicating ongoing research in quantum state stability.

Demonstrating a universal logical gate set in error-detecting surface codes on a superconducting quantum processor - npj Quantum Information
Fault-tolerant quantum computing (FTQC) is essential for achieving large-scale practical quantum computation. Implementing arbitrary FTQC requires the execution of a universal gate set on logical qubits, which is highly challenging. Particularly, in the superconducting system, two-qubit gates on surface code logical qubits have not been realized. Here, we experimentally implement a logical CNOT gate along with arbitrary single-qubit rotation gat…
