Complementarity of quantum correlations in cloning and deleting of quantum states

2015 · Physical Review A

We quantify the amount of correlation generated between two different output modes in imperfect cloning and deletion processes. We use three different measures of quantum correlations and investigate their role in determining the fidelity of …

Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm

2024 · arXiv (Cornell University)

Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search space. Here, we show that a quantum switch can …

Controlled state reconstruction and quantum secret sharing

2024 · Physical Review A

In this article we present a benchmark for resource characterization in the process of controlled quantum state reconstruction and secret sharing for general three-qubit states. This is achieved by providing a closed expression for the …
