Super-Heisenberg scaling of the quantum Fisher information using spin-motion states
Venelin P. Pavlov, Peter A. Ivanov
We propose a spin-motion state for high-precision quantum metrology with super-Heisenberg scaling of the parameter estimation uncertainty using a trapped ion system. Such a highly…

Pseudorandomness, symmetry, smoothing: II
Harm Derksen, Peter Ivanov, Chin Ho Lee +1
We prove several new results on the Hamming weight of bounded uniform and small-bias distributions. We exhibit bounded-uniform distributions whose weight is anti-concentrated, matc…

Resilient functions: Optimized, simplified, and generalized
Peter Ivanov, Emanuele Viola
An -bit boolean function is resilient to coalitions of size if any fixed set of bits is unlikely to influence the function when the other bits are chosen uniformly…
