Variational quantum generative modeling by sampling expectation values of tunable observables

open access: yesnpj Quantum Information
Expectation Value Samplers (EVSs) are quantum generative models that can learn high-dimensional continuous distributions by measuring the expectation values of parameterized quantum circuits. However, these models can demand impractical quantum resources

Geometry of abstraction in quantum computation [PDF]

open access: yes, 2009
Quantum algorithms are sequences of abstract operations, performed on non-existent computers. They are in obvious need of categorical semantics. We present some steps in this direction, following earlier contributions of Abramsky, Coecke and Selinger. In

Superlinear advantage for exact quantum algorithms [PDF]

open access: yes, 2013
A quantum algorithm is exact if, on any input data, it outputs the correct answer with certainty (probability 1). A key question is: how big is the advantage of exact quantum algorithms over their classical counterparts: deterministic algorithms.
