ZZ-Free Two-Transmon CZ Gate Mediated by a Fluxonium Coupler
Junyoung An, Helin Zhang, Qi Ding +19
Eliminating residual ZZ interactions in a two-qubit system is essential for reducing coherent errors during quantum operations. In a superconducting circuit platform, coupling two…
Kinetic Inductance of Few-Layer NbSe in the Two-Dimensional Limit
Sameia Zaman, Joel Î-j. Wang, Thomas Werkmeister +19
Van der Waals (vdW) superconductors remain superconducting down to the monolayer limit, enabling the exploration of emergent physical phenomena and functionality driven by reduced…
Probing Sensitivity near a Quantum Exceptional Point using Waveguide Quantum Electrodynamics
Aziza Almanakly, Reouven Assouly, Harry Hanlim Kang +8
Non-Hermitian Hamiltonians with complex eigenenergies are useful tools for describing the dynamics of open quantum systems. In particular, parity and time (PT) symmetric Hamiltonia…
Emergent Harmonics in Josephson Tunnel Junctions Due to Series Inductance
Junghyun Kim, Max Hays, Ilan T. Rosen +11
Josephson tunnel junctions are essential elements of superconducting quantum circuits. The operability of these circuits presumes a -periodic sinusoidal potential of a tunnel j…
Temperature and Magnetic-Field Dependence of Energy Relaxation in a Fluxonium Qubit
Lamia Ateshian, Max Hays, David A. Rower +14
Noise from material defects at device interfaces is known to limit the coherence of superconducting circuits, yet our understanding of the defect origins and noise mechanisms remai…
Theory of quasiparticle generation by microwave drives in superconducting qubits
Shoumik Chowdhury, Max Hays, Shantanu R. Jha +4
Microwave drives play a central role in the control of superconducting quantum circuits, enabling qubit gates, readout, and parametric interactions. As the drive frequencies are ty…
Non-degenerate noise-resilient superconducting qubit
Max Hays, Junghyun Kim, William D. Oliver
We propose a superconducting qubit based on engineering the first and second harmonics of the Josephson energy and phase relation and . By constructin…
