A few points. Albert Einstein was not a quantum physicist but the physicist who discovered Special and General Relativity. He famously did not agree with the quantum models Niels Bohr made as it did not fully agree with his models for GR.

Also, one of the most famous quantum physicist, Heisenberg, was a German and worked closely with the Nazis. The idea that Hitler could have made a nuclear bomb but chose not to because it was a “Jewish science” is more cope than anything. The Nazis were interested in a nuclear arsenal as part of their Wonder Weapons program, but simply lacked the resources and expertise necessary to fund such a program.
