CoherentNoise

Input quantum state in density matrix format

 theta 

Boolean specifying whether the rotation should be in a semi-random direction

 randomRotation 

Implements a model of coherent noise as used in &lt;DOI:10.1038/s41534-018-0106-y&gt;. It rotates each qubit around the z-axis by the specified amount. If randomRoation is set, it will rotate around the X, Y, or Z axis, which is chosen at random. Randomizing provides interesting side effects but is less representative of quantum noise.

Contains basic structures and operations used frequently in quantum computing. Intended to be a convenient tool to help learn quantum mechanics and algorithms. Can create arbitrarily sized kets and bras and implements quantum gates, inner products, and tensor products. Creates arbitrarily controlled versions of all gates and can simulate complete or partial measurements of kets. Has functionality to convert functions into equivalent quantum gates and model quantum noise. Includes larger applications, such as Steane error correction <DOI:10.1103/physrevlett.77.793>, Quantum Fourier Transform and Shor's algorithm (Shor 1999), Grover's algorithm (1996), Quantum Approximation Optimization Algorithm (QAOA) (Farhi, Goldstone, and Gutmann 2014) <arXiv:1411.4028>, and a variational quantum classifier (Schuld 2018) <arXiv:1804.00633>. Can be used with the gridsynth algorithm <arXiv:1212.6253> to perform decomposition into the Clifford+T set.
