Roadmap to fault tolerant quantum computation using topological qubit arrays

David Aasen, Morteza Aghaee, Zulfi Alam +179

We describe a concrete device roadmap towards a fault-tolerant quantum computing architecture based on noise-resilient, topologically protected Majorana-based qubits. Our roadmap e…

Geometrically Enhanced Topological Quantum Codes

David Aasen, Jeongwan Haah, Matthew B. Hastings +1

We consider geometric methods of ``rotating" the toric code in higher dimensions to reduce the qubit count. These geometric methods can be used to prepare higher dimensional toric…

A Topologically Fault-Tolerant Quantum Computer with Four Dimensional Geometric Codes

David Aasen, Matthew B. Hastings, Vadym Kliuchnikov +8

Topological quantum codes are intrinsically fault-tolerant to local noise, and underlie the theory of topological phases of matter. We explore geometry to enhance the performance o…

Fault-tolerant quantum computation with a neutral atom processor

Ben W. Reichardt, Adam Paetznick, David Aasen +69

Quantum computing experiments are transitioning from running on physical qubits to using encoded, logical qubits. Fault-tolerant computation can identify and correct errors, and ha…

Demonstration of quantum computation and error correction with a tesseract code

Ben W. Reichardt, David Aasen, Rui Chao +15

A critical milestone for quantum computers is to demonstrate fault-tolerant computation that outperforms computation on physical qubits. The tesseract subsystem color code protects…
