- A QUBIT is a “Quantum BIT“
- The QUBIT has the same two states as a classical BIT, 1 / 0, on / off, etc. However, it also has the ability to be a superposition of the two states – i.e both 1 and 0.
Superposition is one of the mind-blowing concepts of quantum physics: the superposed state is a property predicted by Schrodinger’s equation, he of cat-in-the-box fame. (The cat is both dead and alive until you open the box and look!)
This may seem esoteric but scientists are actually using spinning electrons in semi-conductors as qubits to perform elementary logic operations, and classical super-computers use quantum simulation for solving complex equations in astrophysics and climate change. This technology would be perfect for incredibly powerful video processing.
Who knows, the Playstation 16, the RED Epic plus plus plus (where do you go from epic?), the Apple iBrain etc., may all use quantum computing in 50 years time, creating multiple alternative hyperrealities in our minds. Film will still be better though. It’s ’cause the light goes into the emulsion!
