Fault-tolerant quantum computation with a neutral atom processor

Kavli Affiliate: Michael McDonald | First 5 Authors: Ben W. Reichardt, Adam Paetznick, David Aasen, Ivan Basov, Juan M. Bello-Rivas | Summary: Quantum computing experiments are transitioning from running on physical qubits to using encoded, logical qubits. Fault-tolerant computation can identify and correct errors, and has the potential to enable the dramatically reduced logical error […]

Sobolev Versus Homogeneous Sobolev Extension

Kavli Affiliate: Zheng Zhu | First 5 Authors: Pekka Koskela, Riddhi Mishra, Zheng Zhu, , | Summary: In this paper, we study the relationship between Sobolev extension domains and homogeneous Sobolev extension domains. Precisely, we obtain the following results. 1- Let $1leq qleq pleq infty$. Then a bounded $(L^{1, p}, L^{1, q})$-extension domain is also […]

Beyond Coleman’s Instantons

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Vicharit Yingcharoenrat, Ying-li Zhang, , | Summary: In the absence of gravity, Coleman’s theorem states that the $O(4)$-symmetric instanton solution, which is regular at the origin and exponentially decays at infinity, gives the lowest action. Perturbatively, this implies that any small deformation from $O(4)$-symmetry gives […]
