TL;DR: In this article, an optimisation method for variational quantum algorithms is introduced and experimentally demonstrated by obtaining multi-dimensional energy surfaces for small molecules and a spin model. But this method is not suitable for the next generation of variational problems with many physical degrees of freedom.
Journal ArticleDOI
Conditions for factorizable output from a beam splitter
TL;DR: In this paper, it was shown that Gaussian states with the same variance are the only states which bring about factorizable output fields, while it is normal that two independent input fields are superposed at the beam splitter to give correlated outputs.
Journal ArticleDOI
Comment on "Role of initial entanglement and non-Gaussianity in the decoherence of photon-number entangled states evolving in a noisy channel".
TL;DR: A Comment on the Letter by Michele Allegra, Paolo Giorda and Matteo G A Paris, Phys Rev Lett 105, 100503 (2010) The authors of the Letter offer a Reply as mentioned in this paper
Journal ArticleDOI
Oscillator state reconstruction via tunable qubit coupling in Markovian environments
TL;DR: In this paper, a parametrically coupled qubit can be used to fully reconstruct the quantum state of a harmonic oscillator even when both systems are subject to decoherence.
Journal ArticleDOI
Dynamical and steady-state requirements for effective entanglement transfer
TL;DR: In this paper, conditions to entangle two atomic qubits with a two-mode squeezed field driving two cavities containing the atoms were studied and conditions to transfer entanglement from a continuous-variable (CV) to a qubit system were investigated.
