Foliated Quantum Error Correction for Qudits
Gözde Ãstün, Simon J. Devitt, Jason Saied
The paper introduces a method to convert any Pauli‑based quantum error‑correcting code for prime‑dimensional qudits into a foliated graph‑state form that enables fault‑tolerant mea…
Tutorial: Gate-based superconducting quantum computing
Sangil Kwon, Akiyoshi Tomonaga, Gopika Lakshmi Bhai +2
In this tutorial, we introduce basic conceptual elements to understand and build a gate-based superconducting quantum computing system.
Superconducting qubits in the millions: the potential and limitations of modularity
S. N. Saadatmand, Tyler L. Wilson, Mark J. Hodson +11
The development of fault-tolerant quantum computers (FTQCs) is receiving increasing attention within the quantum computing community. Like conventional digital computers, FTQCs, wh…
Comparing Schemes for Creating Qudit Graph States from 16- & 128-dimensional Hilbert Space using Donors in Silicon
Gözde Ãstün, Simon J. Devitt
In this work, we compare two schemes for generating arbitrary qudit graph states using spin qudits in silicon. The first scheme proposes the creation of qudit linear graph states f…
Single-Step Parity Check Gate Set for Quantum Error Correction
Gözde Ãstün, Andrea Morello, Simon Devitt
A key requirement for an effective Quantum Error Correction (QEC) scheme is that the physical qubits have error rates below a certain threshold. The value of this threshold depends…
Near-deterministic photon entanglement from a spin qudit in silicon using third quantisation
Gözde Ãstün, Samuel Elman, Jarryd J. Pla +3
Unlike other quantum hardware, photonic quantum architectures can produce millions of qubits from a single device. However, controlling photonic qubits remains challenging, even at…
