WHY INCLUDED

Martinis develops superconducting quantum hardware, contributing to surface-code architecture and the Sycamore random-circuit experiment, and now works on scalable processor engineering as Qolab’s CTO.

QolabarXiv / Physical Review ANature

Martinis connects superconducting device engineering with the demands of quantum computation. His collaborative surface-code paper makes protection requirements concrete through logical operations and resource estimates. The Sycamore experiment later tested programmable superconducting hardware on a specific sampling benchmark. Its historical performance comparison should be read in that setting, rather than as a claim of advantage for all useful applications. His current Qolab role continues the engineering focus on building and scaling quantum processors.

    Making surface-code computation concrete

    With Austin Fowler, Matteo Mariantoni and Andrew Cleland, Martinis described how surface-code logical qubits and universal operations can be constructed, estimating fault-tolerance requirements and the resources needed for a large quantum computer.

    Coauthor with Austin Fowler, Matteo Mariantoni and Andrew Cleland of the surface-code architecture paper.

    The Sycamore random-circuit experiment

    Martinis coauthored the experiment using 53 programmable superconducting qubits to sample quantum-circuit outputs. The team compared that specific task with classical simulations; the paper’s historical benchmark does not establish universal practical advantage.

    Coauthor of the Sycamore experiment; the benchmark and its interpretation concern the full team’s specific sampling task.

Keep in perspective

Historical Sycamore comparison is qualified; no present-day speedup factor or broad practical advantage is asserted.
