Demonstration of tripartite cat states in two distinct classes of entanglement
May Chee Loke, Jonathan Schwinger, Kehui Yu +4
Entanglement is a cornerstone of quantum mechanics and an essential resource for quantum computation, communication, and metrology. While bipartite entanglement is extensively stud…
Performing SU() operations and rudimentary algorithms in a superconducting transmon qudit for and
Pei Liu, Ruixia Wang, Jing-Ning Zhang +11
Quantum computation architecture based on -level systems, or qudits, has attracted considerable attention recently due to their enlarged Hilbert space. Extensive theoretical and…
Mapping Topology-Localization Phase Diagram with Quasiperiodic Disorder Using a Programmable Superconducting Simulator
Xuegang Li, Huikai Xu, Junhua Wang +23
We explore topology-localization phase diagram by simulating one-dimensional Su-Schrieffer-Heeger (SSH) model with quasiperiodic disorder using a programmable superconducting simul…
Spurious microwave crosstalk in floating superconducting circuits
Peng Zhao, Yingshan Zhang, Xuegang Li +5
Crosstalk is a major concern in the implementation of large-scale quantum computation since it can degrade the performance of qubit addressing and cause gate errors. Finding the or…
Tunable coupling of widely separated superconducting qubits: A possible application towards a modular quantum device
Peng Zhao, Yingshan Zhang, Guangming Xue +2
Besides striving to assemble more and more qubits in a single monolithic quantum device, taking a modular design strategy may mitigate numerous engineering challenges for achieving…
Vacuum-gap transmon qubits realized using flip-chip technology
Xuegang Li, Yingshan Zhang, Chuhong Yang +26
Significant progress has been made in building large-scale superconducting quantum processors based on flip-chip technology. In this work, we use the flip-chip technology to realiz…
Transmon qubit with relaxation time exceeding 0.5 milliseconds
Chenlu Wang, Xuegang Li, Huikai Xu +25
By using the dry etching process of tantalum (Ta) film, we had obtained transmon qubit with the best lifetime (T1) 503 us, suggesting that the dry etching process can be adopted in…
Quantum coherence between cavity and artificial atom in a superconducting circuit QED ladder system
Qichun Liu, Han Cai, Yingshan Zhang +2
We have created a quantum three-level ladder system with the cavity dispersive energy level in a superconducting circuit quantum electrodynamics system consisting of a transmon qub…
