Diagnosing and Restoring the Degraded Fault Distance of Magic State Cultivation
Tim Chan, Armands Strikis, Zhu Sun +1
T-state cultivation is a resource-efficient protocol producing logical T states but recent benchmarks show that its logical error rate is considerably higher than intended i.e. tha…
High-performance syndrome extraction circuits for quantum codes
Armands Strikis, Dan E. Browne, Michael E. Beverland
We present a fast and effective framework for analysing and designing syndrome extraction circuits (SECs). Our approach is based on left--right circuits, a general SEC design that…
Snakes on a Plane: mobile, low dimensional logical qubits on a 2D surface
Adam Siegel, Zhenyu Cai, Hamza Jnane +4
Recent demonstrations indicate that silicon-spin QPUs will be able to shuttle physical qubits rapidly and with high fidelity - a desirable feature for maximising logical connectivi…
Towards early fault tolerance on a 2N array of qubits equipped with shuttling
Adam Siegel, Armands Strikis, Michael Fogarty
It is well understood that a two-dimensional grid of locally-interacting qubits is a promising platform for achieving fault tolerant quantum computing. However in the near-future,…
Adaptive surface code for quantum error correction in the presence of temporary or permanent defects
Adam Siegel, Armands Strikis, Thomas Flatters +1
Whether it is at the fabrication stage or during the course of the quantum computation, e.g. because of high-energy events like cosmic rays, the qubits constituting an error correc…
Quantum LDPC Codes for Modular Architectures
Armands Strikis, Lucas Berent
In efforts to scale the size of quantum computers, modularity plays a central role across most quantum computing technologies. In the light of fault tolerance, this necessitates de…
Quantum computing is scalable on a planar array of qubits with fabrication defects
Armands Strikis, Simon C. Benjamin, Benjamin J. Brown
To successfully execute large-scale algorithms, a quantum computer will need to perform its elementary operations near perfectly. This is a fundamental challenge since all physical…
Learning-based quantum error mitigation
Armands Strikis, Dayue Qin, Yanzhu Chen +2
If NISQ-era quantum computers are to perform useful tasks, they will need to employ powerful error mitigation techniques. Quasi-probability methods can permit perfect error compens…
Quantum leakage detection using a model-independent dimension witness
Armands Strikis, Animesh Datta, George C. Knee
Users of quantum computers must be able to confirm they are indeed functioning as intended, even when the devices are remotely accessed. In particular, if the Hilbert space dimensi…
