Quantum policy gradient algorithms
Sofiene Jerbi, Arjan Cornelissen, Māris Ozols +1
Understanding the power and limitations of quantum access to data in machine learning tasks is primordial to assess the potential of quantum computing in artificial intelligence. P…
Quantum tomography using state-preparation unitaries
Joran van Apeldoorn, Arjan Cornelissen, András Gilyén +1
We describe algorithms to obtain an approximate classical description of a -dimensional quantum state when given access to a unitary (and its inverse) that prepares it. For pure…
A Sublinear-Time Quantum Algorithm for Approximating Partition Functions
Arjan Cornelissen, Yassine Hamoudi
We present a novel quantum algorithm for estimating Gibbs partition functions in sublinear time with respect to the logarithm of the size of the state space. This is the first spee…
Improved Quantum Query Upper Bounds Based on Classical Decision Trees
Arjan Cornelissen, Nikhil S. Mande, Subhasree Patro
Given a classical query algorithm as a decision tree, when does there exist a quantum query algorithm with a speed-up over the classical one? We provide a general construction base…
