Quantum dot quantum computer progress

In Physical Review Letters, Oxford student Avinash Kolli and his coauthors suggest a new way to create entanglement, by identifying two different stable states of a quantum dot (call them ‘A’ and ‘B’) and then targeting two such dots simultaneously with a laser.

A lot of work still needs to be done to flesh out this idea into a full blueprint for a quantum dot computer, but the predictions are testable with existing laboratory equipment. The team is now looking for experimentalists to collaborate on testing this proposal.
