A lower bound on the classical simulation cost of star-network correlations
Martin J. Renner
It is well established that quantum strategies outperform classical ones in several communication tasks. We study the quantum communication complexity of correlations arising from…
Almost all pure entangled states enable unbounded nonlocality sharing
Anna Steffinlongo, Nicola D'Alessandro, Martin J. Renner
We establish a connection between Hardy's paradox and nonlocality sharing in sequential bipartite scenarios, where each subsystem is measured in turn by a chain of observers. We sh…
All pure entangled states can lead to fully nonlocal correlations
Martin J. Renner, Edwin Peter Lobo, Arturo Konderak +2
It is a well-established fact that some quantum correlations can be nonlocal, meaning that they cannot be described by a local hidden variable model. Certain quantum correlations h…
Operationally classical simulation of quantum states
Gabriele Cobucci, Alexander Bernal, Martin J. Renner +1
A classical state-preparation device cannot generate states in relative superposition. We introduce classical models in which devices that are individually unable to generate state…
Absolute dimensionality of quantum ensembles
Alexander Bernal, Gabriele Cobucci, Martin J. Renner +1
The dimension of a quantum state is traditionally seen as the number of superposed distinguishable states in a given basis. We propose an absolute, i.e.~basis-independent, notion o…
Compatibility of Generalized Noisy Qubit Measurements
Martin J. Renner
It is a crucial feature of quantum mechanics that not all measurements are compatible with each other. However, if measurements suffer from noise they may lose their incompatibilit…
Correspondence between entangled states and entangled bases under local transformations
Florian Pimpel, Martin J. Renner, Armin Tavakoli
We investigate whether pure entangled states can be associated to a measurement basis in which all vectors are local unitary transformations of the original state. We prove that fo…
The minimal communication cost for simulating entangled qubits
Martin J. Renner, Marco Túlio Quintino
We analyze the amount of classical communication required to reproduce the statistics of local projective measurements on a general pair of entangled qubits, $|Ψ_{AB}>=\sqrt{p}\ |0…
Classical Cost of Transmitting a Qubit
Martin J. Renner, Armin Tavakoli, Marco Túlio Quintino
We consider general prepare-and-measure scenarios in which Alice can transmit qubit states to Bob, who can perform general measurements in the form of positive operator-valued meas…
Experimentally feasible computational advantage from quantum superposition of gate orders
Martin J. Renner, Časlav Brukner
In an ordinary quantum algorithm the gates are applied in a fixed order on the systems. The introduction of indefinite causal structures allows to relax this constraint and control…
Reassessing the computational advantage of quantum-controlled ordering of gates
Martin J. Renner, Časlav Brukner
Research on indefinite causal structures is a rapidly evolving field that has a potential not only to make a radical revision of the classical understanding of space-time but also…
