Tailoring surface codes for highly biased noise
David K. Tuckett, Andrew S. Darmawan, Christopher T. Chubb +3
The surface code, with a simple modification, exhibits ultra-high error correction thresholds when the noise is biased towards dephasing. Here, we identify features of the surface…
Quantum topology identification with deep neural networks and quantum walks
Yurui Ming, Chin-Teng Lin, Stephen D. Bartlett +1
Topologically ordered materials may serve as a platform for new quantum technologies such as fault-tolerant quantum computers. To fulfil this promise, efficient and general methods…
Braiding defects in topological stabiliser codes of any dimension cannot be universal
Paul Webster, Stephen D. Bartlett
Braiding defects in topological stabiliser codes has been widely studied as a promising approach to fault-tolerant quantum computing. We present a no-go theorem that places very st…
Symmetry-protected self-correcting quantum memories
Sam Roberts, Stephen D. Bartlett
A self-correcting quantum memory can store and protect quantum information for a time that increases without bound with the system size and without the need for active error correc…
Contextuality as a resource for measurement-based quantum computation beyond qubits
Markus Frembs, Sam Roberts, Stephen D. Bartlett
Contextuality - the obstruction to describing quantum mechanics in a classical statistical way - has been proposed as a resource that powers quantum computing. The measurement-base…
Contextuality bounds the efficiency of classical simulation of quantum processes
Angela Karanjai, Joel J. Wallman, Stephen D. Bartlett
Contextuality has been conjectured to be a super-classical resource for quantum computation, analogous to the role of non-locality as a super-classical resource for communication.…
