Random regular graph states are complex at almost any depth
Soumik Ghosh, Dominik Hangleiter, Jonas Helsen
Graph states are fundamental objects in the theory of quantum information due to their simple classical description and rich entanglement structure. They are also intimately relate…
Single-copy stabilizer testing
Marcel Hinsche, Jonas Helsen
We consider the problem of testing whether an unknown -qubit quantum state is a stabilizer state, with only single-copy access. We give an algorithm solving this pro…
Tolerant testing of stabilizer states with a polynomial gap via a generalized uncertainty relation
Zongbo Bao, Philippe van Dordrecht, Jonas Helsen
We prove a conjecture of Arunachalam & Dutt ([AD24]) on the existence of a tolerant stabilizer testing algorithm, and achieve an exponential improvement in the parameters of the te…
Mutual information fluctuations and non-stabilizerness in random circuits
Arash Ahmadi, Jonas Helsen, Cagan Karaca +1
The emergence of quantum technologies has brought much attention to the characterization of quantum resources as well as the classical simulatability of quantum processes. Quantum…
Noise-mitigated randomized measurements and self-calibrating shadow estimation
E. Onorati, J. Kitzinger, J. Helsen +4
Randomized measurements are increasingly appreciated as powerful tools to estimate properties of quantum systems, e.g., in the characterization of hybrid classical-quantum computat…
Quantum PCPs: on Adaptivity, Multiple Provers and Reductions to Local Hamiltonians
Harry Buhrman, Jonas Helsen, Jordi Weggemans
We define a general formulation of quantum PCPs, which captures adaptivity and multiple unentangled provers, and give a detailed construction of the quantum reduction to a local Ha…
