Scaling Alternating-Bias-Assisted Annealing for Precision Transmon Frequency Targeting on Superconducting Quantum Processors
Xiqiao Wang, Mark Field, Teng Zhang +18
Recent advances in the alternating-bias-assisted annealing (ABAA) technique have successfully mitigated intrinsic Josephson-junction (JJ) fabrication variations. This new technique…
Unlocking a fast adiabatic CZ gate and exact residual cancellation between fixed-frequency transmons using a floating tunable coupler
Angela Q. Chen, Xian Wu, Sarah Strong +1
Tunable couplers in superconducting qubit architectures enable strong qubit-qubit interactions for two-qubit gates while suppressing unwanted coupling during single-qubit operation…
Modular Superconducting Qubit Architecture with a Multi-chip Tunable Coupler
Mark Field, Angela Q. Chen, Ben Scharmann +7
We use a floating tunable coupler to mediate interactions between qubits on separate chips to build a modular architecture. We demonstrate three different designs of multi-chip tun…
Full control of superconducting qubits with combined on-chip microwave and flux lines
Riccardo Manenti, Eyob A. Sete, Angela Q. Chen +7
As the field of quantum computing progresses to larger-scale devices, multiplexing will be crucial to scale quantum processors. While multiplexed readout is common practice for sup…
Parametric-resonance entangling gates with a tunable coupler
Eyob A. Sete, Nicolas Didier, Angela Q. Chen +3
High-fidelity parametric gates have been demonstrated with superconducting qubits via rf flux modulation of the qubit frequency. The modulation however leads to renormalization of…
Floating tunable coupler for scalable quantum computing architectures
Eyob A. Sete, Angela Q. Chen, Riccardo Manenti +2
We propose a floating tunable coupler that does not rely on direct qubit-qubit coupling capacitances to achieve the zero-coupling condition. We show that the polarity of the qubit-…
Finite momentum Cooper pairing in 3D topological insulator Josephson junctions
Angela Q. Chen, Moon Jip Park, Stephen T. Gill +4
Unconventional superconductivity arising from the interplay between strong spin-orbit coupling and magnetism is an intensive area of research. One form of unconventional supercondu…
High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy
William Rose, Holger Haas, Angela Q. Chen +4
We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection w…
