A superconducting surface-code processor with lattice-surgery logical operations
Yanzhe Wang, Fanhao Shen, Haipeng Xie +31
Fault-tolerant logical operations are fundamental for scalable quantum computation. Here, we report the experimental realization of lattice-surgery operations between a pair of dis…
Fock space prethermalization and time-crystalline order on a quantum processor
Zehang Bao, Zitian Zhu, Yang-Ren Liu +31
Periodically driven quantum many-body systems exhibit a wide variety of exotic nonequilibrium phenomena and provide a promising pathway for quantum applications. A fundamental chal…
Teleportation transition of surface codes on a superconducting quantum processor
Yiren Zou, Hong-Kuan Xia, Aosai Zhang +32
The topological surface code is a leading candidate for harnessing long-range entanglement to protect logical quantum information against errors, and teleportation of logical state…
Probing Entanglement and Symmetries in Random States Using a Superconducting Quantum Processor
Jia-Nan Yang, Lata Kh Joshi, Filiberto Ares +3
Quantum many-body systems display an extraordinary degree of complexity, yet many of their features are universal: they depend not on microscopic details, but on a few fundamental…
Combinatorial optimization enhanced by shallow quantum circuits with 104 superconducting qubits
Xuhao Zhu, Zuoheng Zou, Feitong Jin +31
A pivotal task for quantum computing is to speed up solving problems that are both classically intractable and practically valuable. Among these, combinatorial optimization problem…
Experimental realization of the bucket-brigade quantum random access memory
Fanhao Shen, Yujie Ji, Debin Xiang +20
