Suppressing Frequency Collisions in a Quantum Processor
Kuljeet Kaur, Xuexin Xu, Mohammad H. Ansari
Frequency crowding, the close spacing of qubit transitions, limits superconducting quantum processors through crosstalk, leakage, and spectator dependent errors. We introduce a Ham…
Parity Cross-Resonance: A Multiqubit Gate
Xuexin Xu, Siyu Wang, Radhika Joshi +2
We present a native three-qubit entangling gate that exploits engineered interactions to realize control-control-target and control-target-target operations in a single coherent st…
Surface-Code Hardware Hamiltonian
Xuexin Xu, Kuljeet Kaur, Chloé Vignes +2
We present a scalable framework for accurately modeling many-body interactions in surface-code quantum processor units (QPUs). Combining a concise diagrammatic formalism with high-…
Modeling and Suppressing Unwanted Parasitic Interactions in Superconducting Circuits
Xuexin Xu
Superconducting qubits are among the most promising candidates for building quantum computers. Despite significant improvements in qubit coherence, achieving a fault-tolerant quant…
Lattice Hamiltonians and Stray Interactions Within Quantum Processors
Xuexin Xu, Manabputra, Chloé Vignes +2
Developing Hamiltonian models for quantum processors with many qubits on the same chip is crucial for advancing quantum computing technologies. Stray couplings between qubits lead…
