Quantum-enhanced measurements without entanglement
2018 · Reviews of Modern Physics
Entangled quantum states can enhance measurement precision. But quantum mechanics harbors other possibilities for enhancing precision, including some that have nothing to do with entanglement. This review surveys various strategies with unentangled probes by which …

Dense coding capacity of a quantum channel
2020 · Physical Review Research
The authors consider a realistic dense coding scenario where noise is affecting both the transmission of quantum systems from the sender (Bob) to the receiver (Alice), and the distribution of the resource state from Alice …

Convex optimization of programmable quantum computers
2020 · npj Quantum Information
Abstract A fundamental model of quantum computation is the programmable quantum gate array. This is a quantum processor that is fed by a program state that induces a corresponding quantum operation on input states. While …

Quantum reading: the experimental set-up
2021 · arXiv (Cornell University)
The protocol of quantum reading refers to the quantum enhanced retrieval of information from an optical memory, whose generic cell stores a bit of information in two possible lossy channels. In the following we analyze …

Symplectic decomposition from submatrix determinants
2021 · Florence Research (University of Florence)
An important theorem in Gaussian quantum information tells us that we can diagonalize the covariance matrix of any Gaussian state via a symplectic transformation. While the diagonal form is easy to find, the process for …
