Riesz Polarization Inequalities in Higher Dimensions

Tamas Erdélyi, Edward B. Saff

We derive bounds and asymptotics for the maximum Riesz polarization quantity $$M_n^p(A) := \max_{{\bold x}_1, {\bold x}_2, \ldots, {\bold x}_n \in A} {\min_{{\bold x} \in A}{\sum_{…

Limits on Preserving Quantum Coherence using Multi-Pulse Control

Kaveh Khodjasteh, Tamás Erdélyi, Lorenza Viola

We explore the physical limits of pulsed dynamical decoupling methods for decoherence control as determined by finite timing resources. By focusing on a decohering qubit controlled…

The size of exponential sums on intervals of the real line

Tamás Erdélyi, Kaveh Khodjasteh, Lorenza Viola

We prove that there is a constant $c > 0$ depending only on $M \geq 1$ and $μ \geq 0$ such that $\int_{y}^{y + a} ∣ g (t) ∣ d t \geq exp (- c / (a δ)), a \in (0, π],$ for every $g$ of…
