These 2 videos are quite cool (in spite of the vocal fry speech) and teach a lot about quantum computing and q-bits in ways that make sense to a non-physicist…
Video 1: 25:38 min – I made a (useless) quantum computer at home
Video 2: 33:15 min – What can my homemade quantum computer do?
Video 1 summary: Since the previous post was about summarizing videos, here is the eightify summary for Video 1. Video 2 is more than 30 min and would only provide partial summary without membership.
Key insights
The computation step involves changing the light state using calcite, allowing for different computations based on the thickness and orientation of the calcite.- The essence of a quantum computer is its ability to transform light in numerous different ways, showcasing the versatility of this technology.
The state of light can be represented as a qubit, showcasing the potential for quantum computing at home.
A quantum computer has an infinite number of states, challenging the traditional binary nature of classical computers.- A qubit is both zero and one at the same time, with any light state being made by adding zero and one.
Using polarizing film to manipulate light in a quantum computer is a clever and innovative approach that simplifies the process.
The calcite splits the light according to its polarization, filtering out different polarizations, which is crucial for starting the quantum computer in a state where both the zero and the one are present at the same time.- I can actually do a real computation and get the right result with my homemade quantum computer, that’s cool.
