TL;DR: In this paper , the authors used the dry etching process of tantalum (Ta) film to obtain transmon qubits with the best lifetime (T1) for multi-qubit fabrication.

TL;DR: In this article, two qubits coupled via a frequency-tunable coupler can adjust the coupling strength, and demonstrate the CZ gate using two different schemes, adiabatic and diabatic methods.

TL;DR: In this paper, the authors used flip-chip technology to realize a modified transmon qubit, denoted as the "flipmon", whose large shunt capacitor is replaced by a vacuum-gap parallel plate capacitor.

TL;DR: In this article, a theoretical analysis of quantum crosstalk impact on simultaneous gate operations in a qubit architecture, where fixed-frequency transmon qubits are coupled via a tunable bus, and sub-100ns controlled-Z (CZ) gates can be realized by applying a baseband flux pulse on the bus.
