Mapping of Lattice Surgery-based Quantum Circuits on Surface Code Architectures

Quantum error correction (QEC) and fault-tolerant (FT) mechanisms are essential for reliable quantum computing. However, QEC considerably increases the computation size up to four orders of magnitude. Moreover, FT implementation has specific requirements on qubit layouts, causing both resource and time overhead. Reducing spatial-temporal costs...

Mapping of quantum algorithms on a quantum chip: 2D topology with nearest neighbor interaction

Quantum algorithms can be described by quantum circuits which consist of quantum bits (qubits) and quantum gates. Such a circuit description assumes that any kind of interaction between qubits is possible. However, quantum chips have limited qubits connectivity only allowing, for instance, nearest-neighbor (NN) interactions. That means, qubits...

Accessibility measures for robustness of the transport system

Accessibility is a key concept in transport and land use policies, and infrastructure-based measures are one important category of accessibility measures. Recently, there has been a significant increase in the attention paid in both academic literature and policy documents to the robustness of the transport system. However, there is not a...
