We investigate how stabilizer theory can be used for constructing sufficient conditions for entanglement. First, we show how entanglement witnesses can be derived for a given state, provided some stabilizing operators of the state are known. These witnesses require only a small effort for an experimental implementation and are robust against noise. Second, we demonstrate that also nonlinear criteria based on uncertainty relations can be derived from stabilizing operators. These criteria can…

Design and experimental performance of local entanglement witness operators
Entanglement is a central concept in quantum information and a key resource for many quantum protocols. In this work we propose and analyze a class of entanglement witnesses that detect the presence
Optimal Verification of Entangled States with Local Measurements.
This work finds the optimal strategy in this case and shows that quadratically fewer total measurements are needed to verify to within a given fidelity than in published results for quantum state tomography, Bell test, or fidelity estimation protocols.
Quantitative entanglement witnesses
All these tests—based on the very same data—give rise to quantitative estimates in terms of entanglement measures, and if a test is strongly violated, one can also infer that the state was quantitatively very much entangled, in the bipartite and multipartite setting.
Entanglement detection via the condition of quantum correlation
We develop a necessary condition of quantum correlation. It is utilized to construct a $d$-level bipartite Bell-type inequality which is strongly resistant to noise and requires only analyses of
Universal N-Partite d-Level Pure-State Entanglement Witness Based on Realistic Measurement Settings.
This work derives experimentally optimized witnesses that are able to detect multipartite d-level cluster states, and that require only two measurement settings, to confirm the presence of probed quantum states using methods that are compatible with practical experimental realizations in different quantum platforms.
Entanglement verification with realistic measurement devices via squashing operations
Many protocols and experiments in quantum information science are described in terms of simple measurements on qubits. However in a real implementation the exact description is more difficult and

Multi-qubit stabilizer and cluster entanglement witnesses
Abstract.One of the problems concerning entanglement witnesses (EWs) is the construction of them by a given set of operators. Here several multi-qubit EWs called stabilizer EWs are constructed by
Entanglement witnesses for families of the bound entangled three-qubit states
We construct three-qubit entanglement witnesses with relatively simple structures. Despite their simplicity, these witnesses are capable of detecting a number of bound entangled states more
The structure of ultrafine entanglement witnesses
An entanglement witness is an observable with the property that a negative expectation value signals the presence of entanglement. The question arises how a witness can be improved if the expectation


Optimization of entanglement witnesses
An entanglement witness (EW) is an operator that allows to detect entangled states. We give necessary and sufficient conditions for such operators to be optimal, i.e. to detect entangled states in an
Multiparticle entanglement purification for graph states.
We introduce a class of multiparticle entanglement purification protocols that allow us to distill a large class of entangled states. These include cluster states, Greenberger-Horne-Zeilinger states,
Separability and Distillability of Multiparticle Quantum Systems
We present a family of 3-qubit states to which any arbitrary state can be depolarized. We fully classify those states with respect to their separability and distillability properties. This provides a
Entanglement as a precondition for secure quantum key distribution.
We demonstrate that a necessary precondition for an unconditionally secure quantum key distribution is that both sender and receiver can use the available measurement results to prove the presence of
Detecting genuine multipartite entanglement with two local measurements.
These witnesses are robust against noise and require only two local measurement settings when used in an experiment, independent of the number of qubits, which allows detection of entanglement for an increasing number of parties without a corresponding increase in effort.
Configuration of separability and tests for multipartite entanglement in bell-type experiments.
It is proved that when the two measured observables are assumed to precisely anticommute, a stronger quadratic inequality can be used as a witness of full n-partite entanglement.

A family of necessary separability criteria for finite-dimensional systems is derived based on inequalities for variances of observables based on covariance matrices and it is shown that every pure bipartite entangled state violates some of these inequalities.
Two Measurement Settings can Suffice to Verify Multipartite Entanglement
We present entanglement witnesses for detecting genuine multi‐qubit entanglement. Our constructions are robust against noise and require only two local measurement settings, independent of the number
Fragility of a class of highly entangled states with n qubits
We consider a quantum computer with $n$ quantum bits (``qubits''), where each qubit is coupled independently to an environment affecting the state in a dephasing or depolarizing way. For mixed states
Experimental detection of multipartite entanglement using witness operators.
A canonical way of constructing and decomposing witness operators so that they can be directly implemented with present technology is introduced and applied to three- and four-qubit entangled states of polarized photons, giving experimental evidence that the considered states contain true multipartite entanglement.
