Nguyen Ba An, 2010. Joint remote state preparation via W and W-type states. Optics Communications, Vol.283, 4113-4117

In 2008, Professor Nguyen Ba An and his colleague put forward a new protocol (which they named Joint Remote State Preparation – JRSP) that allows two or more individuals, only by means of local operation and classical communication, to faithfully co-prepare a quantum state at a remote location without leaking the information to anyone, including the preparers themselves.  The key idea is to split the full set of information of the state to be co-prepared into subsets, each sent to a preparer. The conventional ways of information splitting are suitable for shared quantum channels in the form of GHZ and EPR entangled states, but do not suit to the so-called W or W-type entangled states. In the award-winning work, a new way of information splitting is proposed allowing JRSP to be performed, regardless of the entanglement degree of the W or W-type states, and without the need of having high-tech equipments at the receiver’s location. The acronym “JRSP” has been recognized in the community.
