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…
How significant are the known collision and element distinctness quantum algorithms?
Lov Grover, Terry Rudolph
Quantum search is a technique for searching N possibilities in only O(sqrt(N)) steps. It has been applied in the design of quantum algorithms for several structured problems. Many…
Photon-number superselection and the entangled coherent-state representation
Barry C. Sanders, Stephen D. Bartlett, Terry Rudolph +1
We introduce the entangled coherent state representation, which provides a powerful technique for efficiently and elegantly describing and analyzing quantum optics sources and dete…
On continuous-variable entanglement with and without phase references
S. J. van Enk, Terry Rudolph
We discuss how continous-variable quantum states such as coherent states and two-mode squeezed states can be encoded in phase-reference independent ways.
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…
