RESEARCH
Connecting quantum devices to exploit their full potential is the next step in establishing useful applications of quantum technologies and making them accessible to a wide audience. Building such a quantum internet requires the development of new protocols, for example for entanglement distillation, certification and distribution of quantum states. We approach these issues not only from a fundamental perspective, but also consider practical limitations - such as decoherence, noise and imperfections - and analyze both their effects and ways to minimize them.
News & Activities
New Pre-Print: Entanglement and purity can help to detect systematic experimental errors
We examine how the characteristics of a quantum state influence the detectability of systematic errors in quantum experiments using the direct and efficient detection method introduced in this work.
New Pre-Print: Merging-Based Quantum Repeater
We introduce an alternative approach for the design of quantum repeaters based on generating entangled states of growing size.
Our Research on designing entanglement structures for quantum networks has been published
In this work we demonstrate that shaping the entanglement topology of a quantum network is crucial for its performance and flexibility.
New Pre-Print: Graph State Fission
We introduce a simple, yet powerful, protocol that allows a qubit in a graph state to split while preserving selective connections, using minimum entanglement overhead.
A flexible quantum data bus for quantum networks
We present a new measurement scheme that allows for the parallel extraction of multiple Bell states from a two-dimensional cluster state, while maintaining the connectivity of the remaining cluster state.
New Pre-Print: Improving entanglement purification through coherent superposition of roles
We propose alternative entanglement purification approaches, leveraging coherent superpositions of the roles of entangled states to enhance protocol efficiency.
Our Research on the analysis of noise on entanglement-based networks has been published
Here we show that cluster states and tree graph states are useful entanglement resources in a quantum network under the effects of white noise.
