Chris Chan and Lu Sham’s theory on using the more robust multiphoton states to entangle two distant electron spins is published in PRL. The proposed method has the potential of much higher probability of success in entanglement by measurement projection than the current single photon method. Entanglement of two spins in two separate quantum dots is the requisite precursor to quantum information processing in semiconductor systems. Lu Sham is discussing with his experimental collaborators how to implement the scheme.
