The certification of entanglement dimensionality is of great importance in characterizing quantum systems. Recently, it was pointed out that quantum correlation of high-dimensional states can be simulated with a sequence of lower-dimensional states. Such a problem may render existing characterization protocols unreliable—the observed entanglement may not be a truly high-dimensional one. Here, we introduce the notion of irreducible entanglement to capture its dimensionality that is… 
Experimental demonstration of measurement-device-independent measure of quantum steering
This research introduces a measure of steerability in an MDI scenario, and proves that such a measure satisfies the convex steering monotone and is robust against not only measurement biases but also losses.
Relating an entanglement measure with statistical correlators for two-qudit mixed states using only a pair of complementary observables
We focus on characterizing entanglement of high dimensional bipartite states using various statistical correlators for two-qudit mixed states. The salient results obtained are as follows: (a) A
Device-independent certification of the Hilbert-space dimension using a family of Bell expressions
A family of Bell expressions where Alice and Bob perform 2n−1 and n number of dichotomic measurements respectively which serve as the device-independent dimension witnesses of Hilbert space of 2 dimensions which determines the success probability of a communication game known as n-bit parity-oblivious random access code.

Measurements in two bases are sufficient for certifying high-dimensional entanglement
It is shown how carefully constructed measurements in two bases can be used to faithfully and efficiently certify bipartite high-dimensional states and their entanglement for any physical platform by measuring quantum states twice in two different bases.
Experimental witness of genuine high-dimensional entanglement
This work presents the experimental realizing of creation and detection, by the normalized witness operation, of the notion of genuine high-dimensional entanglement, which cannot be decomposed into lower-dimensional Hilbert space and thus form theEntanglement structures existing in high- dimensional systems only.
Implementation of a measurement-device-independent entanglement witness.
This work constructs an attack on the conventional entanglement witness process and demonstrates that a separable state can be falsely identified to be entangled, and designs and experimentally demonstrates a measurement-device-independent entangling witness for a variety of two-qubit states.
Resource-Efficient Measurement-Device-Independent Entanglement Witness.
The theory of MDI-EW is extended to remove the necessity of prior knowledge about the two-qubit states to be witnessed and the robustness of this approach against noise is demonstrated by witnessing entanglement down to an entangled state fraction close to 0.4.
Experimental Measurement-Device-Independent Entanglement Detection
This experimental demonstration of measurement-device-independent (MDI) entanglement detection using witness method for general two qubits photon polarization systems can be generalized for the investigation of properties of quantum systems and for the realization of cryptography and communication protocols.
Measurement-device-independent entanglement witnesses for all entangled quantum states.
This work introduces the concept of measurement-device-independent entanglement witnesses (MDI-EWs), which allow one to demonstrateEntanglement of all entangled quantum states with untrusted measurement apparatuses, and shows how to systematically obtain such MDI-ews from standard entangler witnesses.
Characterizing Genuine Multilevel Entanglement.
This work presents a general theory to characterize those high-dimensional quantum states for which the correlations cannot simply be simulated by low-dimensional systems, and leads to general criteria for detecting multilevel entanglement in multiparticle quantum states.

This work considers the task of randomness certification and shows that randomness can be certified in a variety of cases, including single-partite experiments or setups using only separable states.
Generation and confirmation of a (100 × 100)-dimensional entangled quantum system
A novel nonlinear criterion is developed which infers entanglement dimensionality of a global state by using only information about its subspace correlations, which allows very practical experimental implementation as well as highly efficient extraction of entanglements dimensionality information.
Quantifying Entanglement of Maximal Dimension in Bipartite Mixed States.
A framework for lower bounding the appropriate measure of entanglement, the so-called G-concurrence, is derived through few local measurements and it is shown that these bounds have relevant applications also for multipartite states.
