Tunable coupler for realizing a controlled-phase gate with dynamically decoupled regime in a superconducting circuit
X. Li, T. Cai, H. Yan +13
Controllable interaction between superconducting qubits is desirable for large-scale quantum computation and simulation. Here, based on a theoretical proposal by Yan et al. [Phys.…
Experimental implementation of universal nonadiabatic geometric quantum gates in a superconducting circuit
Yuan Xu, Ziyue Hua, Tao Chen +9
Using geometric phases to realize noise-resilient quantum computing is an important method to enhance the control fidelity. In this work, we experimentally realize a universal nona…
Error-transparent operations on a logical qubit protected by quantum error correction
Y. Ma, Y. Xu, X. Mu +8
Universal quantum computation is striking for its unprecedented capability in processing information, but its scalability is challenging in practice because of the inevitable envir…
Heisenberg limited single-mode quantum metrology
W. Wang, Y. Wu, Y. Ma +11
Two-mode interferometers, such as Michelson interferometer based on two spatial optical modes, lay the foundations for quantum metrology. Instead of exploring quantum entanglement…
Observation of topological magnon insulator states in a superconducting circuit
Weizhou Cai, Jiaxiu Han, Feng Mei +9
Searching topological states in artificial systems has recently become a rapidly growing field of research. Meanwhile, significant experimental progresses on observing topological…
