• Abstract: Hyperbolic quantum error correction codes (HQECCs) leverage the unique geometric properties of hyperbolic space to enhance the capabilities and performance of quantum error correction. By embedding qubits in hyperbolic lattices, HQECCs achieve higher encoding rates and improved error thresholds compared to conventional Euclidean codes. Building on recent advances in hyperbolic crystallography, we present a systematic framework for constructing HQECCs. As a key component of this framework, we develop a novel algorithm for computing all plaquette cycles and logical operators associated with a given HQECC. To demonstrate the effectiveness of this approach, we utilize this framework to simulate two HQECCs based respectively on two relevant examples of hyperbolic tilings. In the process, we evaluate key code parameters such as encoding rate, error threshold, and code distance for different sub-lattices. This work establishes a solid foundation for a systematic and comprehensive analysis of HQECCs, paving the way for the practical implementation of HQECCs in the pursuit of robust quantum error correction strategies.

  Quantum Error Correction Codes (QECCs) are pivotal in advancing quantum computing by protecting quantum states against the adverse effects of noise and errors. Despite significant improvements in the field of QECCs, a unified methodology for evaluating them on a consistent basis has remained elusive.

We develop a systematic strategy for selecting QECCs that adapts to the specific requirements of a given scenario, facilitating a tailored approach to quantum error correction.

  We present a study of crosstalk errors in a quantum-computing architecture based on a single string of ions confined by a radio-frequency trap, and manipulated by individually-addressed laser beams. This type of errors affects spectator qubits that, ideally, should remain unaltered during the application of single- and two-qubit quantum gates addressed at a different set of active qubits. We microscopically model crosstalk errors from first principles and present a detailed study showing the importance of using a coherent vs incoherent error modelling and, moreover, discuss strategies to actively suppress this crosstalk at the gate level.
