Fault-tolerant quantum computation with a neutral atom processor

Posted by klaurent MIT

Kavli Affiliate: Michael McDonald | 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 rates required for valuable algorithms. However, it requires flexible control of high-fidelity operations performed on large numbers […]

Exploiting epitaxial strained germanium for scaling low noise spin qubits at the micron-scale

Posted by dbos Delft

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Lucas E. A. Stehouwer, Cécile X. Yu, Barnaby van Straaten, Alberto Tosato, Valentin John | Summary: Disorder in the heterogeneous material stack of semiconductor spin qubit systems introduces noise that compromises quantum information processing, posing a challenge to coherently control large-scale quantum devices. Here, we exploit low-disorder […]

Sobolev Versus Homogeneous Sobolev Extension

Posted by dbos UCAS

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

Posted by klaurent Tokyo

Kavli Affiliate: Misao Sasaki | 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 a larger action. In this letter we investigate the possibility of extending […]

Quantitative guiding of developmental cell fate transitions using gene-free modelling

Posted by dbos Rockefeller

Kavli Affiliate: Eric D. Siggia | Authors: Ismail Hajji, Eric D Siggia, Francis Corson and Wolfgang Keil | Summary: During development, cells gradually assume specialized fates via changes of transcriptional dynamics in thousands of genes. Terminal cell identities are then stabilized through the convergence of gene regulatory network dynamics and the accumulation of epigenetic DNA […]

Coexistence vs collapse in transposon populations

Posted by klaurent Caltech

Kavli Affiliate: Nathan Lewis | Summary:Transposons are small, self-replicating DNA sequences found in every branch of life. Often, one transposon will parasitize another, forming a tiny intracellular ecosystem. In some species these ecosystems thrive, while in others they go extinct, yet little is known about when or why this occurs. Here, we present a stochastic […]
