How useful is a home-made quantum computer?

By | January 3, 2024

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.
