Scalable Implementation of Boson Sampling with Trapped Ions
Scalable Implementation Boson Sampling Trapped Ions
2016/1/22
Boson sampling solves a classically intractable problem by sampling from a probability distribution given by matrix permanents. We propose a scalable implementation of boson sampling using local trans...

Harmonic analysis of spherical sampling in diffusion MRI
Harmonic analysis spherical sampling diffusion MRI
2011/9/9
In the last decade diffusion MRI has become a powerful tool to non-invasively study white-matter integrity in the brain. Recently many research groups have focused their attention on multi-shell spher...
Comparing parallel and simulated tempering enhanced sampling algorithms at phase transition regimes
parallel tempering simulated tempering first-order phase transitions Ising and lattice-gas models
2010/11/19
Two important enhanced sampling algorithms, simulated (ST) and parallel (PT) tempering,are commonly used when ergodic simulations may be hard to achieve, e.g, due to a phase space separated by large f...
In a sampling problem, we are given an input x ∈ {0, 1}n, and asked to sample approximately
from a probability distribution Dx over poly (n)-bit strings. In a search problem, we are given an input x ...
