If you received a ban, it's a ban from the whole Schengen area. If you haven't received a ban, formally you can still (try to) enter any Schengen country, including Poland but the reasons that led to being denied entry in the first place might still hold and the denial itself will weight against you.
If they notice the cancelled entry stamp (that should be) in your passport, border guards in other Schengen countries are likely to evaluate your situation more carefully than usual. But they are still allowed to let you enter, if they think it's appropriate. Either way, it's difficult to know for sure in advance.
Furthermore, if you need a visa (that would depend on your nationality), you need to apply for it in advance.
