Unemployment law depends greatly on individual state statutes and case law. In Washington State, if you give two weeks notice and the employer does not allow you to serve out the two weeks (i.e., it asks you to leave right away or at some time before the two weeks is up), the case is adjudicated a termination/firing/discharge. At an unemployment hearing, the focus will shift to whether you had done something to cause your termination and whether this something rises to the level of "misconduct." "Layoff" is a very specific term with several elements that must be met first. People who are laid off are eligible for unemployment, and employers do not usually appeal this decision.
