Macroscopic entanglement between a Bose Einstein condensate and a superconducting loop

Mandip Singh

We theoretically study macroscopic entanglement between a magnetically trapped Bose-Einstein condensate and a superconducting loop. We treat the superconducting loop in a quantum superposition of two different flux states coupling with the magnetic trap to generate macroscopic entanglement. The scheme also provides a platform to investigate interferometry with an entangled Bose Einstein condensate and to explore physics at the quantum-classical interface.

Macroscopic Entanglement of a Bose-Einstein Condensate on a Superconducting Atom Chip

Mandip Singh

We present a practically implementable scheme to realise macroscopic entanglement of a Bose-Einstein condensate on a superconducting atom chip. Our proposal combines the two emerging fields of micro-manipulation of a Bose-Einstein condensate on an atom chip and quantum coherent dynamics in superconducting circuits. Our idea is based on coupling a superconductor flux loop to a Bose-Einstein condensate in a magnetic trap on an atom chip. We treat the superconductor flux loop in quantum superposition of two flux states. Our scheme also provides a platform to realise entangled atoms interferometry through a Bose-Einstein condensate on an atom chip.

Josephson Persistent-Current Qubit

Johan E. Mooij, Terry P. Orlando, Leonid S Levitov +3 more

A qubit was designed that can be fabricated with conventional electron beam lithography and is suited for integration into a large quantum computer. The qubit consists of a micrometer-sized loop with three or four Josephson junctions; the two qubit states have persistent currents of opposite direction. Quantum superpositions of these states are obtained by pulsed microwave modulation of the enclosed magnetic flux by currents in control lines. A superconducting flux transporter allows for controlled transfer between qubits of the flux that is generated by the persistent currents, leading to entanglement of qubit information.
