Achieving perfect completeness in classical-witness quantum Merlin-Arthur proof systems
Stephen P. Jordan, Hirotada Kobayashi, Daniel Nagaj +1
This paper proves that classical-witness quantum Merlin-Arthur proof systems can achieve perfect completeness. That is, QCMA = QCMA1. This holds under any gate set with which the H…
Local two-qubit entanglement-annihilating channels
Sergey N. Filippov, Tomas Rybar, Mario Ziman
We address the problem of the robustness of entanglement of bipartite systems (qubits) interacting with dynamically independent environments. In particular, we focus on characteriz…
Optimized t-expansion method for the Rabi Hamiltonian
Igor Travenec, Ladislav Samaj
A polemic arose recently about the applicability of the -expansion method to the calculation of the ground state energy of the Rabi model. For specific choices of the tria…
Scavenging quantum information: Multiple observations of quantum systems
Peter Rapcan, John Calsamiglia, Ramon Munoz-Tapia +2
Given an unknown state of a qudit that has already been measured optimally, can one still extract any information about the original unknown state? Clearly, after a maximally infor…
Purification of genuine multipartite entanglement
Marcus Huber, Martin Plesch
In tasks, where multipartite entanglement plays a central role, state purification is, due to inevitable noise, a crucial part of the procedure. We consider a scenario exploiting t…
Quantum learning algorithms for quantum measurements
Alessandro Bisio, Giacomo Mauro D'Ariano, Paolo Perinotti +1
We study quantum learning algorithms for quantum measurements. The optimal learning algorithm is derived for arbitrary von Neumann measurements in the case of training with one or…
Heisenberg's Uncertainty Relation and Bell Inequalities in High Energy Physics
A. Di Domenico, A. Gabriel, B. C. Hiesmayr +7
An effective formalism is developed to handle decaying two-state systems. Herewith, observables of such systems can be described by a single operator in the Heisenberg picture. Thi…
Extremal quantum protocols
Giacomo Mauro D'Ariano, Paolo Perinotti, Michal Sedlak
Generalized quantum instruments correspond to measurements where the input and output are either states or more generally quantum circuits. These measurements describe any quantum…
A Computable Criterion for Partial Entanglement in Continuous Variable Quantum Systems
Andreas Gabriel, Marcus Huber, Sasa Radic +1
A general and computable criterion for k-(in)separability in continuous multipartite quantum systems is presented. The criterion can be experimentally implemented with a finite and…
