Understanding the resource consumption in distributed scenarios is one of the main goals of quantum information theory. A prominent example for such a scenario is the task of quantum state merging, where two parties aim to merge their tripartite quantum state parts. In standard quantum state merging, entanglement is considered to be an expensive resource, while local quantum operations can be performed at no additional cost. However, recent developments show that some local operations could be…

Quantum state merging with bound entanglement

This work provides general conditions for a state to admit perfect merging, and presents a family of fully separable states which cannot be perfectly merged if the merging parties have no access to additional singlets.

Quantum state redistribution with local coherence

Quantum entanglement and coherence are two fundamental resources for quantum information processing. Recent results clearly demonstrate their relevance in quantum technological tasks, including

Hierarchy of quantum operations in manipulating coherence and entanglement

The hierarchies of different operations for manipulating coherence and entanglement in distributed settings, where at least one of the two spatially separated parties are restricted from generating coherence, are established and no inclusion holds between the maximal operations with one restricted party and those with two restricted parties.

A few limits to Quantum Information Theory

The thesis examines the limits imposed on quantum information theory due to the probability structure of mixed states and concludes by discussing another limit that superposition imposes on quantum theory, the impossibility to clone coherence of an arbitrary state.

Comparing coherence and entanglement under resource non-generating unitary transformations

Quantum coherence is a fundamental property of quantum systems that can be studied within the framework of a quantum resource theory. From this resource-theoretic approach, many similarities emerge

Genuine quantum coherence

This framework captures coherence under additional constrains such as energy preservation and all genuinely incoherent operations are incoherent regardless of their particular experimental realization, and introduces the full class of operations with this property, which is called fully incoherent.

Resource conversion between operational coherence and multipartite entanglement in many-body systems

A set of resource conversion relationships between quantum coherence and multipartite entanglement in many-body systems, where the operational measures of resource cost and distillation are focused, is established and a scheme for cyclic interconversion between coherent and GME in three-qubit systems without loss is presented.

Quantumness of quantum channels

Quantum coherence is a fundamental aspect of quantum physics and plays a central role in quantum information science. This essential property of the quantum states could be fragile under the

Experimental study of quantum coherence decomposition and trade-off relations in a tripartite system

Quantum coherence is the most fundamental of all quantum quantifiers, underlying other well-known quantities such as entanglement. It can be distributed in a multipartite system in various ways—for

Resource theories of quantum coherence: foundations and applications

This thesis concentrates on understanding quantum coherence in the mathematical framework of resource theories, viewing it both as a resource to be harnessed and as a way to quantitatively characterise quantum states in contrast to classical states.
