To produce an operable quantum computer that is made with imperfect hardware, we must design and test scalable quantum error correcting codes that are suited for the devices we can build and, in unison, develop decoding strategies that accommodate device-specific noise characteristics. Here, we introduce the dynamic compass code, a subsystem code with a novel syndrome extraction cycle, that...

Scalable realisation of quantum computing is reliant on the development of fault tolerant devices. Analysis of quantum error correction protocols typically considers incoherent noise models or noise-free syndrome measurements. While this is simple to simulate classically and straightforward to compute analytically, these simplifications are unable to capture the full dynamics of a noisy...

542. Overhead of quantum error correction with biased-noise qubits

AIP | Quantum Science and Technology (QST)

Contributed Oral

Quantum error-correcting codes allow for fault-tolerant quantum computation with noisy hardware, but they incur an overhead: multiple noisy qubits are required to encode and manipulate quantum information robustly. One way to reduce this overhead is to use biased-noise qubits, with structured noise channels dominated by a single error type, such as dephasing or erasure. These errors are much...

633. Spatiotemporal Pauli processes: an operational framework for correlated noise in quantum error correction

AIP | Quantum Science and Technology (QST)

Contributed Oral

Correlated noise is a central challenge for scalable quantum error correction: temporal memory and spatial structure can concentrate otherwise rare faults into bursts that evade the assumptions behind standard threshold estimates. However, there remains a gap between microscopic non-Markovian open system dynamics and the stochastic Pauli error models used in stabilizer code simulation and...

593. Surface Code Transversal CNOT Performance on a Trapped Ion Quantum Processor

Spiro Gicev (The University of Melbourne)

AIP | Quantum Science and Technology (QST)

Contributed Oral

Practical implementation of Fault-Tolerant Quantum Computation (FTQC) relies on a means to efficiently mediate logical qubit interactions. Transversal Controlled-NOT (CNOT) gates solve this task by using a set of corresponding operations between associated data qubits across two code blocks. Device properties such as the number of available qubits and connectivity limitations have, until...

441. Recovery Algorithm for Correlated Errors in Permutation-Invariant Quantum Codes

Omprakash Chandra (Macquarie University)

AIP | Quantum Science and Technology (QST)

Contributed Oral

Quantum Error Recovery (QER) uses knowledge of the error channel acting on a quantum system to find optimal recovery maps. The scheme restores the uncorrupted state with a fidelity exceeding that achieved by noise parameter independent quantum error correction. We use a generic coherent QER map implemented with a quantum circuit acting on the system together with ancillary qubits to recover...
