An InAsSb surface quantum well with in-situ deposited Nb as a platform for semiconductor-superconductor hybrid devices
Sjoerd Telkamp, Zijin Lei, Tommaso Antonelli +7
We present a novel semiconductor-superconductor hybrid material based on a molecular beam epitaxially grown InAsSb surface quantum well with an in-situ deposited Nb top layer. Rela…
Resource-Efficient Cross-Platform Verification with Modular Superconducting Devices
Kieran Dalton, Johannes Knörzer, Finn Hoehne +7
Large-scale quantum computers are expected to benefit from modular architectures. Validating the capabilities of modular devices requires benchmarking strategies that assess perfor…
Realizing Lattice Surgery on Two Distance-Three Repetition Codes with Superconducting Qubits
Ilya Besedin, Michael Kerschbaum, Jonathan Knoll +12
Quantum error correction is needed for quantum computers to be capable of fault-tolerantly executing algorithms using hundreds of logical qubits. Recent experiments have demonstrat…
Realization of Constant-Depth Fan-Out with Real-Time Feedforward on a Superconducting Quantum Processor
Yongxin Song, Liberto Beltrán, Ilya Besedin +8
When using unitary gate sequences, the growth in depth of many quantum circuits with output size poses significant obstacles to practical quantum computation. The quantum fan-out o…
