Quantum mechanics is Markov chains in imaginary time.
- teamonkey 2y agoCan you explain that?
- diegoperini 2y agoState transitions are probabilistic and operators have complex coefficients.
- tsimionescu 2y agoState transitions are deterministic, it's only measurement that is probabilistic.
- Filligree 2y agoEven that is arguable. Subjective experience is probabilistic… kinda.
- guntars 2y agoDo atoms decay deterministically?
- wfewras 2y agoI saw the best minds of my generation pithposting on hn.
- Filligree 2y agoYes, aka. continuously. Interactions with larger systems makes it appear discontinuous.
- tsimionescu 2y agoAs long as they are isolated, their state is a superposition of all possible states, and evolves determinsitically, with the amplitude of each of these "sub-states" evolving perfectly determinsitically. If you want to perform a measurement, you choose a possible decomposition of the superposition state and measure along that axis, and you'll get one of the values along that axis, with a probability that is the modulus of the square of the (complex) amplitude of that value.
