Quantum state targeting
Terry Rudolph, Robert W. Spekkens
We introduce a new primitive for quantum communication that we term "state targeting" wherein the goal is to pass a test for a target state even though the system upon which the te…
Optimal measurements for relative quantum information
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens
We provide optimal measurement schemes for estimating relative parameters of the quantum state of a pair of spin systems. We prove that the optimal measurements are joint measureme…
Robust polarization-based quantum key distribution over collective-noise channel
J. -C. Boileau, D. Gottesman, R. Laflamme +2
We present two polarization-based protocols for quantum key distribution. The protocols encode key bits in noiseless subspaces or subsystems, and so can function over a quantum cha…
Unambiguous discrimination of mixed states
Terry Rudolph, Robert W. Spekkens, Peter Shipley Turner
We present the conditions under which probabilistic error-free discrimination of mixed states is possible, and provide upper and lower bounds on the maximum probability of success…
Classical and quantum communication without a shared reference frame
Stephen D. Bartlett, Terry Rudolph, R. W. Spekkens
We show that communication without a shared reference frame is possible using entangled states. Both classical and quantum information can be communicated with perfect fidelity wit…
