Weak distillation of quantum resources
Shinnosuke Onishi, Oliver Hahn, Ryuji Takagi
Importance sampling based on quasi-probability decomposition is the backbone of many widely used techniques, such as error mitigation, circuit knitting, and, more generally, virtua…
Measuring non-Gaussianity with Correlation
Oliver Hahn, Ryuji Takagi
Quantum non-Gaussianity is a key resource for quantum advantage in continuous-variable systems. We introduce a general framework to quantify non-Gaussianity based on correlation ge…
Classical simulation of circuits with realistic odd-dimensional Gottesman-Kitaev-Preskill states
Cameron Calcluth, Oliver Hahn, Juani Bermejo-Vega +2
Classically simulating circuits with bosonic codes is challenging due to the prohibitive cost of simulating quantum systems with many, possibly infinite, energy levels. We propose…
Assessing non-Gaussian quantum state conversion with the stellar rank
Oliver Hahn, Maxime Garnier, Giulia Ferrini +2
State conversion is a fundamental task in quantum information processing. Quantum resource theories allow for analyzing and bounding conversions that use restricted sets of operati…
Bridging magic and non-Gaussian resources via Gottesman-Kitaev-Preskill encoding
Oliver Hahn, Giulia Ferrini, Ryuji Takagi
Although the similarity between non-stabilizer states -- also known as magic states -- in discrete-variable systems and non-Gaussian states in continuous-variable systems has widel…
Classical simulation and quantum resource theory of non-Gaussian optics
Oliver Hahn, Ryuji Takagi, Giulia Ferrini +1
We propose efficient algorithms for classically simulating Gaussian unitaries and measurements applied to non-Gaussian initial states. The constructions are based on decomposing th…
