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…
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…
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…
Scalable surface code decoders with parallelization in time
Xinyu Tan, Fang Zhang, Rui Chao +2
Fast classical processing is essential for most quantum fault-tolerance architectures. We introduce a sliding-window decoding scheme that provides fast classical processing for the…
Optimization of the surface code design for Majorana-based qubits
Rui Chao, Michael E. Beverland, Nicolas Delfosse +1
The surface code is a prominent topological error-correcting code exhibiting high fault-tolerance accuracy thresholds. Conventional schemes for error correction with the surface co…
Finding Angles for Quantum Signal Processing with Machine Precision
Rui Chao, Dawei Ding, Andras Gilyen +2
We describe an algorithm for finding angle sequences in quantum signal processing, with a novel component we call halving based on a new algebraic uniqueness theorem, and another w…
Quantum dimension test using the uncertainty principle
Rui Chao, Ben W. Reichardt
We propose a test for certifying the dimension of a quantum system: store in it a random -bit string, in either the computational or the Hadamard basis, and later check that the…
Flag fault-tolerant error correction for any stabilizer code
Rui Chao, Ben W. Reichardt
Conventional fault-tolerant quantum error-correction schemes require a number of extra qubits that grows linearly with the code's maximum stabilizer generator weight. For some comm…
Permutation-invariant constant-excitation quantum codes for amplitude damping
Yingkai Ouyang, Rui Chao
The increasing interest in using quantum error correcting codes in practical devices has heightened the need for designing quantum error correcting codes that can correct against s…
Test to separate quantum theory from non-signaling theories
Rui Chao, Ben W. Reichardt
A Bell test separates quantum mechanics from a classical, local realist theory of physics. However, a Bell test cannot separate quantum physics from all classical theories. Classic…
Fault-tolerant quantum computation with few qubits
Rui Chao, Ben W. Reichardt
Reliable qubits are difficult to engineer, but standard fault-tolerance schemes use seven or more physical qubits to encode each logical qubit, with still more qubits required for…
Quantum error correction with only two extra qubits
Rui Chao, Ben W. Reichardt
Noise rates in quantum computing experiments have dropped dramatically, but reliable qubits remain precious. Fault-tolerance schemes with minimal qubit overhead are therefore essen…
Overlapping qubits
Rui Chao, Ben W. Reichardt, Chris Sutherland +1
An ideal system of qubits has dimensions. This exponential grants power, but also hinders characterizing the system's state and dynamics. We study a new problem: the qubi…
Test for a large amount of entanglement, using few measurements
Rui Chao, Ben W. Reichardt, Chris Sutherland +1
Bell-inequality violations establish that two systems share some quantum entanglement. We give a simple test to certify that two systems share an asymptotically large amount of ent…
Superactivation of quantum gyroscopes
Giulio Chiribella, Rui Chao, Yuxiang Yang
Quantum particles with spin are the most elementary gyroscopes existing in nature. Can two such gyroscopes help two distant observers find out their relative orientation in space?…
