Quantum state transfer (QST) provides a method to send arbitrary quantum states from one system another. Such concept is crucial for transmitting information into the memory, processor, and network. The standard benchmark of QST average fidelity between prepared received states. In this work, we provide new which reveals non-classicality based on spatio-temporal steering (STS). More specificall...

We introduce the quantum Gaussian process state, motivated via a statistical inference for wave function supported by data set of unentangled product states. show that this condenses down to compact and expressive parametric form, with variational flexibility shown be competitive or surpassing established alternatives. The connections state its roots as Bayesian machine well matrix states, also...
