Parameterized quantum circuits as universal generative models for continuous multivariate distributions

npj Quantum Information
Parameterized quantum circuits are a key component of quantum machine learning models for regression, classification, and generative tasks. Quantum Circuit Born machines produce discrete distributions over bitstrings whose length is exactly the number of

Higher-Order Quantum-Inspired Genetic Algorithms [PDF]

, 2014
This paper presents a theory and an empirical evaluation of Higher-Order Quantum-Inspired Genetic Algorithms. Fundamental notions of the theory have been introduced, and a novel Order-2 Quantum-Inspired Genetic Algorithm (QIGA2) has been presented ...

Non-orientable AdS3 and its holography

Journal of High Energy Physics
Known solutions to three-dimensional gravity with negative cosmological constant consist of either AdS3 or its orbifolds (or orientifolds). We geometrically derive a novel non-orientable AdS3 spacetime that is an orientifold of a spinor double cover of ...

Understanding the Quantum Computational Speed-up via De-quantisation [PDF]

Electronic Proceedings in Theoretical Computer Science, 2010
While it seems possible that quantum computers may allow for algorithms offering a computational speed-up over classical algorithms for some problems, the issue is poorly understood.

Coreset Clustering on Small Quantum Computers

, 2020
Many quantum algorithms for machine learning require access to classical data in superposition. However, for many natural data sets and algorithms, the overhead required to load the data set in superposition can erase any potential quantum speedup over ...

Quantum Hypercomputation - Hype or Computation? [PDF]

, 2007
A recent attempt to compute a (recursion--theoretic) non--computable function using the quantum adiabatic algorithm is criticized and found wanting.

Quantum Genetic Algorithms for Computer Scientists

Computers, 2016
Genetic algorithms (GAs) are a class of evolutionary algorithms inspired by Darwinian natural selection. They are popular heuristic optimisation methods based on simulated genetic mechanisms, i.e., mutation, crossover, etc.
