"Controlling Exciton Qubits: Manipulating Quantum Oscillations in a Bose-Einstein Condensate"
Researchers propose a top-down approach to building a large quantum register using a Bose-Einstein condensate (BEC) of excitons. By generating and controlling macroscopic quantum states of BEC consisting of millions of identical excitons, they aim to overcome the challenges of short-lived phenomena and ultra-low temperatures typically associated with quantum computing. The use of a superfluid BEC state can prevent quantum decoherence and enable faster quantum gate operations. The proposed system shows promise for scalability and offers computational capabilities and redundancy for quantum error correction.
