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…
Gibbs-preserving operations requiring infinite amount of quantum coherence
Hiroyasu Tajima, Ryuji Takagi
Gibbs-preserving operations have been studied as one of the standard free processes in quantum thermodynamics. Although they admit a simple mathematical structure, their operationa…
Quantum Dynamic Programming
Jeongrak Son, Marek Gluza, Ryuji Takagi +1
We introduce a quantum extension of dynamic programming, a fundamental computational method that efficiently solves recursive problems using memory. Our innovation lies in showing…
