Pooling quantum states obtained by indirect measurements
Robert W. Spekkens, H. M. Wiseman
We consider the pooling of quantum states when Alice and Bob both have one part of a tripartite system and, on the basis of measurements on their respective parts, each infers a qu…
Reference frames, superselection rules, and quantum information
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens
Recently, there has been much interest in a new kind of ``unspeakable'' quantum information that stands to regular quantum information in the same way that a direction in space or…
Quantum Error Correcting Subsystems are Unitarily Recoverable Subsystems
David W. Kribs, Robert W. Spekkens
We show that every correctable subsystem for an arbitrary noise operation can be recovered by a unitary operation, where the notion of recovery is more relaxed than the notion of c…
How to observe a coherent superposition of an atom and a molecule
Mark R. Dowling, Stephen D. Bartlett, Terry Rudolph +1
We demonstrate that it is possible, in principle, to perform a Ramsey-type interference experiment to exhibit a coherent superposition of a single atom and a diatomic molecule. Thi…
Degradation of a quantum reference frame
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens +1
We investigate the degradation of reference frames, treated as dynamical quantum systems, and quantify their longevity as a resource for performing tasks in quantum information pro…
