Introduction to quantum Algorithms
In this node, we will change gears and discuss the basics of the classical Discrete Fourier transform (DFT), which has made a significant impact in the field of signal processing for transforming data from the time domain to the frequency domain and back. The DFT is a unitary transformation, which makes it a good candidate for quantum computers
In this module we are going to learn about an algorithm that helps us estimate the eigenvalue of a given unitary operator. The eigenvectors of a unitary operator form an orthonormal basis set. Applying the unitary operator on one of its eigenvectors multiplies it by a global phase (the eigenvalue). For unitary operators, the eigenvalues have magnitude and can be written in the form , where is called the eigenphase corresponding to the eigenvalue.
Working on Shor's algorithm. Modular arithmetic is a fundamental concept of basic mathematics. We say that two integers are equivalent modulo if the difference between them is a multiple of , that is, there exists an integer such that . In order to understand this type of equivalence it is common to work with a "clock"-like picture, which will have hours instead of . We will say that two numbers are equivalent if they mark the same hour on the clock.
In module A, we sped up the lock-breaking process by testing states in pairs. This told us when the solution was present, but not which state it was. Our goal now will be to try and figure out the state directly, and our broad strategy will be to start in the uniform superposition and somehow "pump" amplitude from the other states into , so that we measure the solution with high probability. This strategy is called amplitude amplification. Let's start by exploring what happens to amplitudes when we apply the oracle.
In this module, we'll learn about Hamiltonian Simulations. Fundamentally, quantum computing is different from classical computing because of the physical laws working "under the hood" of the computer. To understand quantum computing in this light, it's useful to treat Nature as a sort of black box. It takes an initial condition as an input, evolves it using physical laws, and outputs experimental data (aka measurements) at the end. We can try to infer the laws of Nature from looking at the pattern of input conditions and output measurements.
