In this paper we propose to use a quantum computer in a different way, such that we not only have access to the lowenergy states but to the whole spectrum for certain quantum many-body problems. This allows us to prepare ...

The emergence of an interference pattern suggested that each electron was interfering with itself, and therefore in some sense the electron had to be going through both slits at once. Clearly, this inter ...
