Designing FTQC Architectures Under Realistic Hardware Noise with Plaquette by Prof. Martin Plenio
Designing FTQC Architectures Under Realistic Hardware Noise with Plaquette
A seminar with Prof. Martin Plenio
Abstract
Fault tolerance demands that the noise in a quantum device is suppressed below the threshold of a quantum error-correcting code. The design of such devices typically relies on fast stabiliser simulators, which assume stochastic Pauli noise. Real hardware, however, rarely conforms to this idealised model: superconducting qubits can leak out of the computational subspace, neutral atoms can scatter through intermediate states, trapped ions can heat, and spin qubits can couple to low-lying valley states.
To address these limitations, we developed Plaquette, a design software platform that quantifies the logical performance of a fault-tolerant architecture under realistic, physically derived hardware imperfections.
In this talk, Dr. Plenio will show how Plaquette answers questions that are beyond the reach of both Clifford and full-state simulators, and will discuss how it can guide design decisions that help hardware teams reach fault tolerance faster.
About the speaker
Prof. Martin B. Plenio held a full professorship at Imperial College London until 2009, when he became an Alexander von Humboldt Professor at Ulm University. He currently leads the Institute of Theoretical Physics and the Center for Quantum BioSciences. He is a co-founder of NVision Quantum Technologies and a co-founder and Scientific Advisor of QC Design.
Prof. Plenio is one of the most highly cited researchers in quantum science. His seminal contributions span entanglement theory, quantum many-body systems, quantum information processing, quantum sensing, quantum technologies for the life sciences, and the modelling of realistic noise in quantum systems. A central theme of his work is connecting theoretical insight with experimental reality.
At QC Design, Prof. Plenio helps guide the scientific direction behind Plaquette, the company’s quantum error-correction simulation and design software. His research has long shaped how the field understands the gap between idealized noise models and the imperfections of real hardware, a question that lies at the heart of both QC Design’s mission and this seminar.
