Learner struggles to grasp how qubits store information

Original: my first attempt at grasping what's going on with trying to store information as "qubits" (units of # quantum computing)

A physics enthusiast has shared a first attempt at understanding how quantum computers store information in qubits, admitting the effort failed. The core puzzle: how can a physical system hold data while existing in multiple superposed states at once? The writer wonders whether keeping everything near absolute zero is key, a reference to the extreme cooling many quantum machines require to keep qubits stable.

Why now: Quantum computing is a fast-moving topic and the counterintuitive physics of qubits makes it hard to understand, prompting discussion.

• my first attempt at grasping what's going on with trying to store information as "qubits" (units of # quantum computing) quite failed. how does one store information in a physical system capable of existing in multiple superposed states? if everything were near absolute zero… · mxchara@cyberpunk.lol · 2
