Phased outcome-complete simulation
Vadym Kliuchnikov, Adam Paetznick, Marcus P. da Silva
We generalize the polynomial-time outcome-complete simulation algorithm for stabilizer circuits in arXiv:2309.08676 to track global phases exactly, yielding what we call phased out…
Excising dead components in the surface code using minimally invasive alterations: A performance study
Ryan V. Mishmash, Vadym Kliuchnikov, Juan Bello-Rivas +7
The physical implementation of a large-scale error-corrected quantum processor will necessarily need to mitigate the presence of defective (thereby "dead") physical components in i…
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…
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…
