A double-resonator coupler for high-fidelity two-qubit gates between superconducting qubits
Seunghyeon Jin, Seungha Woo, Shinyoung Hwang +6
Tunable couplers have enabled two-qubit gate fidelities in superconducting quantum processors to approach , yet simultaneously suppressing residual interactions and maintai…
Universal Spin Screening Clouds in Local Moment Phases
Minsoo L. Kim, Jeongmin Shim, H. -S. Sim +1
When a local impurity spin interacts with conduction electrons whose density of states (DOS) has a (pseudo)gap or diverges at the Fermi energy, a local moment (LM) phase can be fav…
Electrical control of a Kondo spin screening cloud
Ngoc Han Tu, Donghoon Kim, Minsoo L. Kim +8
Quantitative analysis of quantum many-body systems, consisting of numerous itinerant electrons that interact with localized spins or electrons, is a long-standing issue. The Kondo…
Symmetric improved estimators for multipoint vertex functions
Jae-Mo Lihm, Johannes Halbinger, Jeongmin Shim +3
Multipoint vertex functions, and the four-point vertex in particular, are crucial ingredients in many-body theory. Recent years have seen significant algorithmic progress toward nu…
