    "abstract": "We theoretically study specific schemes for performing a fundamental\ntwo-qubit quantum gate via controlled atomic collisions by switching\nmicroscopic potentials. In particular we calculate the fidelity of a gate\noperation for a configuration where a potential barrier between two atoms is\ninstantaneously removed and restored after a certain time. Possible\nimplementations could be based on microtraps created by magnetic and electric\nfields, or potentials induced by laser light.",
