Quantum estimation via sequential measurements
2015 · New Journal of Physics
The problem of estimating a parameter of a quantum system through a series of measurements performed sequentially on a quantum probe is analyzed in the general setting where the underlying statistics is explicitly non-i.i.d. We …

Quantum resource control for noisy Einstein-Podolsky-Rosen steering with qubit measurements
2016 · Physical Review A
We demonstrate how quantum optimal control can be used to enhance quantum resources for bipartite one-way protocols, specifically Einstein-Podolsky-Rosen steering with qubit measurements. Steering is relevant for one-sided device-independent key distribution, the realistic implementations of …

Control of Quantum Noise: On the Role of Dilations
2022 · Annales Henri Poincaré
Abstract We show that every finite-dimensional quantum system with Markovian (i.e. GKLS-generated) time evolution has an autonomous unitary dilation which can be dynamically decoupled. Since there is also always an autonomous unitary dilation which cannot …

A Multi-Qubit Quantum Gate Using the Zeno Effect
2023 · Quantum
The Zeno effect, in which repeated observation freezes the dynamics of a quantum system, stands as an iconic oddity of quantum mechanics. When a measurement is unable to distinguish between states in a subspace, the …
