Was energy already quantized 10^-43 seconds after the Big Bang?

Main Question or Discussion Point

Good evening. I am wondering if energy has always been quantized. I read that the shortest time after the Big Bang (the time it took for gravity to separate first) was 10^-43 seconds. At these moments of earliest symmetry breaking, was energy already discrete, or did quantum mechanics emerge some time afterwards?

Thank you in advance.

This should probably be moved to the quantum physics forum, but, the short answer is after T = 0 + planck time, the rules of quantum physics appear to be in charge of the universe.

Which particles existed at the Planck time?
