Bypassing state initialization in Hamiltonian tomography on spin-chains
TL;DR: In this article, the authors provide an extensive discussion on a scheme for Hamiltonian tomography of a spin-chain model that does not require state initialization and represents a genuine instance of a control-limited quantum protocol.
Proceedings ArticleDOI
Experimental implementation of delayed-choice decoherence suppression
TL;DR: In this paper, the authors proposed a delayed-choice decoherence suppression protocol using photonic entanglement, which successfully demonstrated that the choice to suppress decoherency can be delayed after decoheration and even after the detection of a qubit.

TL;DR: It is shown that the security level of the protocol against photon number (PNS) attack is enhanced, relative to the BB84 protocol.

TL;DR: In this article, a new optimisation method for variational quantum algorithms is introduced and experimentally demonstrated a 100-fold improvement in efficiency compared to naive implementations. But the method is not suitable for the next generation of variational problems with many physical degrees of freedom.
