Programming

Quantum Programming - Abstraction level 2: State Machine and Algorithms

After we get an intuition about phase kickback, we start getting into actual Computer Science, through building a State Machine, and recreating an actual Quantum Algorithm.

Programming

Quantum Programming - Abstraction level 1: Logic Gates

For the majority of our time spent programming on the quantum computer, we will be thinking of the qubits in their state of superposition. What would be useful for our intuition now, would be to have a way to visualise this superposition, so we can analyse the effects each logical gate has on it.

Programming

Quantum Programming by abstracting ourselves from Quantum Mechanics: Abstraction level 0

Just as we know that in classical computers we manipulate logical zeroes and ones, we can get an idea of what we are dealing with in the lowest level of logic in a quantum computer.

Lifestyle

8 Tips and Ideas for Living and Being Productive in Small Spaces

I've always strived to organise my living space in a practical manner, so that I can both live comfortably there, and be as productive as the place allowed for. Here are some ideas from my own experience of making this work.

Science

Celestial Navigation - coordinate systems

It's just like remembering where a distant house at an edge of a field is, then moving around the field, and checking where the house is now relative to us. If the house was distant enough, and coincidentally always north of you, you would call it the polar star.
