1. A method for performing a non-classical computation, comprising:
(a) at a first magneto-optical trap (MOT), cooling one or more atoms to a first temperature, wherein said first MOT comprises a three-dimensional (3D) MOT;
(b) at a second MOT, cooling said one or more atoms from said first temperature to a second temperature that is lower than said first temperature;
(c) generating a plurality of spatially distinct optical trapping sites, said plurality of optical trapping sites configured to trap a plurality of atoms comprising at least said one or more atoms, wherein said plurality of atoms comprises one or more qubits, wherein said plurality of atoms comprises an atom comprising two valence electrons, and wherein said atom of said plurality of atoms is trapped in an optical trapping site of said plurality of optical trapping sites by an attractive force;
(d) applying electromagnetic energy to one or more atoms of said plurality of atoms, to perform a sequence of qubit gate operations, wherein a qubit gate operation within said sequence of qubit gate operations comprises:
(i) inducing said one or more atoms to adopt one or more superposition states of a first atomic state and at least a second atomic state that is different from said first atomic state; or
(ii) inducing said one or more atoms to adopt one or more superposition states of a first atomic state and at least a second atomic state that is different from said first atomic state and quantum mechanically entangling at least a subset of said one or more atoms in said one or more superposition states with at least another atom of said plurality of atoms; and
(e) performing one or more measurements of said one or more superposition states to obtain said non-classical computation, wherein said non-classical computation is encoded in said sequence of qubit gate operations.
