Tight adversary bounds for composite functions
Peter Hoyer, Troy Lee, Robert Spalek
The quantum adversary method is a versatile method for proving lower bounds on quantum algorithms. It yields tight bounds for many computational problems, is robust in having many…
Deterministic Entanglement of Assistance and Monogamy Constraints
Gilad Gour, David A. Meyer, Barry C. Sanders
Certain quantum information tasks require entanglement of assistance, namely a reduction of a tripartite entangled state to a bipartite entangled state via local measurements. We e…
Classical and quantum fingerprinting with shared randomness and one-sided error
Rolf T. Horn, A. J. Scott, Jonathan Walgate +3
Within the simultaneous message passing model of communication complexity, under a public-coin assumption, we derive the minimum achievable worst-case error probability of a classi…
Notes on super-operator norms induced by Schatten norms
John Watrous
This paper considers basic properties of super-operator norms induced by Schatten p-norms. Such super-operator norms arise in various contexts in the study of quantum information.…
Geometric phase for an adiabatically evolving open quantum system
Ingo Kamleitner, James D. Cresser, Barry C. Sanders
We derive an elegant solution for a two-level system evolving adiabatically under the influence of a driving field with a time-dependent phase, which includes open system effects s…
Geometric phase distributions for open quantum systems
K. -P. Marzlin, S. Ghose, B. C. Sanders
In an open system, the geometric phase should be described by a distribution. We show that a geometric phase distribution for open system dynamics is in general ambiguous, but the…
