High School Can a quantum particle be simulated on a classical computer?

Click For Summary
Simulating a quantum particle on a classical computer raises fundamental questions about the nature of simulation itself. A classical simulation cannot replicate the exact properties of a quantum particle, as it relies on different underlying mechanisms, such as transistors. The term "exactly like" is deemed meaningless without specifying the parameters of similarity and difference. Therefore, the feasibility of such a simulation depends on the criteria set for comparison. Ultimately, the distinction between simulation and reality complicates the possibility of achieving a true replication of quantum behavior on classical systems.

I'm just curious, is it possible to simulate a quantum particle (so that it is exactly like a real quantum particle) merely using a classical computer? When something is simulated on a classical computer, it's not really actually there, what you see on the screen is just pixels lighting up. The thing you are simulating is just a bunch of transistors turned on or off. Does this mean it's impossible to simulate a particle on a classical computer?

A simulation is always something different from the thing simulated. ''exactly like'' is meaningless, since ''like'' always allows for ''not exactly''. You need to describe in which way you want a simulation to be alike, and in which way you allow it to differ, before you get a meaningless statement.
 
Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
