Hard decoding algorithm for optimizing thresholds under general Markovian noise
Christopher Chamberland, Joel J. Wallman, Stefanie Beale +1
Quantum error correction is instrumental in protecting quantum systems from noise in quantum computing and communication settings. Pauli channels can be efficiently simulated and t…
Contextuality under weak assumptions
Andrew W. Simmons, Joel J. Wallman, Hakop Pashayan +2
The presence of contextuality in quantum theory was first highlighted by Bell, Kochen and Specker, who discovered that for quantum systems of three or more dimensions, measurements…
Bounding the average gate fidelity of composite channels using the unitarity
Arnaud Carignan-Dugas, Joel J. Wallman, Joseph Emerson
There is currently a significant need for robust and efficient methods for characterizing quantum devices. While there has been significant progress in this direction, there remain…
Representations of the multi-qubit Clifford group
Jonas Helsen, Joel J. Wallman, Stephanie Wehner
The Clifford group is a fundamental structure in quantum information with a wide variety of applications. We discuss the tensor representations of the -qubit Clifford group, whi…
Estimating the coherence of noise in quantum control of a solid-state qubit
Guanru Feng, Joel J. Wallman, Brandon Buonacorsi +6
To exploit a given physical system for quantum information processing, it is critical to understand the different types of noise affecting quantum control. Distinguishing coherent…
