TOOLS FOR QUANTUM ALGORITHMS [PDF]
International Journal of Modern Physics C, 1999 We present efficient implementations of a number of operations for quantum computers. These include controlled phase adjustments of the amplitudes in a superposition, permutations, approximations of transformations and generalizations of the phase adjustments to block matrix transformations.

Quantum annealing with twisted fields
New Journal of Physics, 2022 Quantum annealing (QA) is a promising method for solving combinational optimization problems and performing quantum chemical calculations. The main sources of errors in QA are the effects of decoherence and non-adiabatic transition.

Improving quantum algorithms for quantum chemistry [PDF]
Quantum Information and Computation, 2015 We present several improvements to the standard Trotter-Suzuki based algorithms used in the simulation of quantum chemistry on a quantum computer. First, we modify how Jordan-Wigner transformations are implemented to reduce their cost from linear or logarithmic in the number of orbitals to a constant.

Quantum Algorithm for Spectral Regression for Regularized Subspace Learning
IEEE Access, 2019 In this paper, we propose an efficient quantum algorithm for spectral regression which is a dimensionality reduction framework based on the regression and spectral graph analysis. The quantum algorithm involves two core subroutines: the quantum principal

Quantum algorithmic entropy [PDF]
Proceedings 16th Annual IEEE Conference on Computational Complexity, 2001 We extend algorithmic information theory to quantum mechanics, taking a universal semicomputable density matrix (``universal probability'') as a starting point, and define complexity (an operator) as its negative logarithm. A number of properties of Kolmogorov complexity extend naturally to the new domain. Approximately, a quantum state is simple if it
