#Hadamard

This is the first in a series of four articles based on my Jupyter Notebooks exploring quantum computing as a tool for generating random number distributions.

Many of the introductory quantum computing articles and courses out there are not quite right. They either quickly head deep into details that require a University-level physics or mathematics background, or sit at a high level based on analogies that are out of step with how quantum computers actually work. I want to try something different, and introduce some useful quantum computing algorithms using high-school level maths. I will avoid much (but maybe not all) of the jargon, and show how the algorithms can be implemented on the commonly available Qiskit platform.

Is this #math question about #Hadamard matrices unresolved? Is there a \(k\) such that there is no \( 4k \times 4k)\ matrix \(H)\ with -1 or 1 entries such that \(H H^t=4k Id)\?

A basic introduction to #QIBO with a link to online python notebook plus accompanying slides which I used for a tutorial for understands at #NTU #SG.

The examples include:
- basic #Clifford group generators such as Z, X and #Hadamard,
- Preparing a #Bellstate with a #CNOT
- #swaptest, sampling and histograms
