Abstract
A quantum computing device and method employs qubit arrays of entangled states using negative refractive index lenses. A qubit includes a pair of neutral atoms separated by or disposed on opposite sides of a negative refractive index lens. The neutral atoms and negative refractive index lens are selectively energized and/or activated to cause entanglement of states of the atoms. The quantum computing device enjoys a novel architecture that is workable and scalable in terms of size and wavelength.
Claims20
A quantum computing system comprising:
- a plurality of qubits, each quibit comprising a pair of atoms;
- and a negative index lens disposed between the pair of atoms;
- control circuitry operatively connected to the negative index lenses, the control circuitry being operable to switch the negative index lenses between a negative index state and a positive index state;
- and
- atomic state reading circuitry configured to determine atomic spin states of the atoms.
2 more elements
A quantum computing device comprising:
- a plurality of neutral atoms, each pair of neutral atoms being separated by a negative index lens, wherein each pair of neutral atoms and negative index lens are arranged to define a quantum bit;
- and
- control circuitry operatively coupled to one or more excitation sources, wherein the control circuitry and one or more excitation sources cooperate to entangle the quantum bits.
