Controllable non-Hermitian qubit-qubit Coupling in Superconducting quantum Circuit
Hui Wang, Yan-Jun Zhao, Xun-Wei Xu
We propose a theoretical scheme to realize the controllable non-Hermitian qubit-qubit coupling by adding a high-loss resonator in tunable coupling superconducting quantum circuit.…
Logarithmic light cone, slow entanglement growth, and quantum memory
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +4
Effective light cones, characterized by Lieb-Robinson bounds, emerge in nonrelativistic local quantum systems. Here, we present several analytical results derived from logarithmic…
Control the qubit-qubit coupling in the superconducting circuit with double-resonator couplers
Hui Wang, Yan-Jun Zhao, Hui-Chen Sun +5
We propose a scheme of using two fixed frequency resonator couplers to tune the coupling strength between two Xmon qubits. The induced indirect qubit-qubit interactions by two reso…
Bounded light cone and robust topological order out of equilibrium
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +3
The ground state degeneracy of topologically ordered gapped Hamiltonians is the bedrock for self-correcting quantum memories, which are unfortunately not stable away from equilibri…
Quarter-wave Resonator Based Tunable Coupler for Xmon Qubits
Hui Wang, Yan-Jun Zhao, Rui Wang +4
We propose a scheme of tunable coupler based on quarter-wave resonator for scalable quantum integrated circuits. The open end of the T-type resonator is capacitively coupled to two…
Simulation of Quantum Computing on Classical Supercomputers
Ya-Qian Zhao, Ren-Gang Li, Jin-Zhe Jiang +6
Simulation of quantum computing on supercomputers is a significant research topic, which plays a vital role in quantum algorithm verification, error-tolerant verification and other…
