How to Build a Quantum Supercomputer: Scaling from Hundreds to Millions of Qubits
Masoud Mohseni, Artur Scherer, K. Grace Johnson +48
In the span of four decades, quantum computation has evolved from an intellectual curiosity to a potentially realizable technology. Today, small-scale demonstrations have become po…
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-…
Statistics of Strongly Coupled Defects in Superconducting Qubits
S. Weeden, D. C. Harrison, S. Patel +8
Decoherence in superconducting qubits is dominated by defects that reside at amorphous interfaces. Interaction with discrete defects results in dropouts that complicate qubit opera…
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…
