Journal Article
Ringbauer, M., Bromley, T. R., Cianciaruso, M., Lami, L., Lau, W. S., Adesso, G., …Piani, M. (2018). Certification and quantification of multilevel quantum coherence. Physical Review X, 8(4), Article 041007. https://doi.org/10.1103/physrevx.8.041007

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within... Read More about Certification and quantification of multilevel quantum coherence.

Accessible bounds for general quantum resources (2018)
Journal Article

The recent development of general quantum resource theories has given a sound basis for the quantification of useful quantum effects. Nevertheless, the evaluation of a resource measure can be highly non-trivial, involving an optimisation that is ofte... Read More about Accessible bounds for general quantum resources.

Characterizing genuine quantum resources and determining operational rules for their manipulation are crucial steps to appraise possibilities and limitations of quantum technologies. Two such key resources are nonclassicality, manifested as quantum s... Read More about Converting multilevel nonclassicality into genuine multipartite entanglement.

Role of non-Markovianity and backflow of information in the speed of quantum evolution (2017)
Journal Article
Cianciaruso, M., Maniscalco, S., & Adesso, G. (2017). Role of non-Markovianity and backflow of information in the speed of quantum evolution. Physical Review A, 96(1), Article 012105. https://doi.org/10.1103/PhysRevA.96.012105

We consider a two-level open quantum system undergoing pure dephasing, dissipative, or multiply decohering dynamics and show that whenever the dynamics is non-Markovian, the initial speed of evolution is a monotonic function of the relevant physical...

The ability to live in coherent superpositions is a signature trait of quantum systems and constitutes an irreplaceable resource for quantum-enhanced technologies. However, decoherence effects usually destroy quantum superpositions. It has been recen... Read More about Observation of time-invariant coherence in a nuclear magnetic resonance quantum simulator.
