Quantum algorithm formulas - A quantum algorithm is given to evaluate formulas over any finite boolean gate set. We propose an algorithm based on variational quantum imaginary time evolution for solving the Feynman-Kac partial differential equation resulting from a multidimensional system of stochastic differential equations. Provided that the complexities of the input subformulas to any gate differ by at most a constant factor the algorithm has optimal query complexity. Although originally discovered from a different point of view Grovers algorithm can be regarded as a special case of formula evaluation in which every gate is OR.
The output of this algorithm is identical to that of the HHL Quantum Linear-Solving Algorithm except while HHL provides a much more favourable computation speedup over VQLS the variational nature of our algorithm allows for it to be performed on NISQ quantum computers while HHL would require much more robust quantum hardware and many more. Applying the algorithm for st-connectivity to Boolean formula evaluation problems we match the OsqrtN bound on the quantum query complexity of evaluating formulas on N variables give a quadratic speed-up over the classical query complexity of a certain class of promise Boolean formulas and show this approach can yield superpolynomial. The runtime complexity of the algorithm is polynomial in the size of F and the condition number of certain Macaulay matrix associated with F. The main new tool is a correspondence between a classi-.

By incorporating a controlled-state preparatory step to the Bayesian phase difference estimation BPDE quantum algorithm they earlier formulated the scientists measured the superposition of the vacuum wave function with zero electrons and the wave function of the preferred electronic state surpassing the need to mimic the time evolution of the wave. The algorithm is optimal on read-once formulas for which each gates inputs are balanced in a certain sense. We give a quantum algorithm for evaluating formulas over an extended gate set including all two- and three-bit binary gates eg NAND 3-majority. Even higher-order formulas specifically 2kth-order for k0 can be constructed recursively.
Both inputs 0 1 are mapped to the output 0. After efficient preprocessing it is nearly time optimal. We show that by simply randomizing how the terms in the Hamiltonian are ordered one can prove stronger bounds for product formulas and thereby give more efficient quantum simulations. Shors Algorithm 51 Quantum Fourier Transform Quantum Fourier Transform is a quantum implementation of the discreet Fourier transform.
In many cases the quantum formula-evaluation algorithms are efficient not only in query complexity but also in time-complexity. It assumes that the input vector b is given as a quantum state of logN qubits b Σ i b i i. First the quantum approximate optimization algorithm QAOA is discussed which is a polynomial-time algorithm for finding an approximate solution to a classical optimization problem with a desired accuracy.

A quantum query algorithm computes f exactly if the output equals fX with probabilityp1 for all X01N. We also discuss an application of quantum simulation to an algorithm for linear systems. Quantum algorithms for approximate function loading. The algorithm is derived using the span program framework.
Complexity is equal to the number of queries and is denoted by QEf Buhrman and de Wolf 2002. Loading classical data into quantum computers represents an essential stage in many relevant quantum algorithms especially in the field of quantum machine learning. Quantum parallelism I Suppose classical algorithm computes f. You might be familiar with the discreet Fourier Trans-form or Fourier Analysis from the context of signal processing linear algebra or one of its many other applications.
The simplest is the following fourth order k2 formula originally introduced by Suzuki. It is related to the quantum adiabatic algorithm but. The span-program formalism also yields quantum query complexity lower bounds. As a consequence the authors give a polynomial-time quantum algorithm for solving Boolean equation systems if their condition numbers are polynomial in the size of F.
A quantum algorithm for such applications termed HHL after its developers Harrow Hassidim and Lloyd makes use of methods from Hamiltonian simulation. The Deutsch-Jozsa algorithm first introduced in Reference 1 was the first example of a quantum algorithm that performs better than the best classical algorithm. Two of those algorithms will be described in detail in this tutorial in order to better elucidate the study of quantum computing theory and quantum algorithm design.
