Quantifying the fidelity of a quantum memory
Victor Barizien, Sophie Egelhaaf, Angelo Gelmini Rodriguez +5
Quantum memories are key ingredients for future quantum networks. Developing methods for their certification is therefore an important, yet challenging, problem. In this work, we p…
Bell and EPR experiments with signalling data
Lucas Maquedano, Sophie Egelhaaf, Amro Abou-Hachem +4
The no-signalling principle is a fundamental assumption in Bell-inequality and quantum-steering experiments. Nonetheless, experimental imperfections can lead to apparent violations…
Certification of quantum networks using the generalised Choi isomorphism
Sophie Egelhaaf, Roope Uola
We present a framework for certifying entanglement properties of quantum states and measurements in line networks. The framework is based on the generalised Choi isomorphism, which…
Certifying high-dimensional quantum channels
Sophie Engineer, Suraj Goel, Sophie Egelhaaf +9
The use of high-dimensional systems for quantum communication opens interesting perspectives, such as increased information capacity and noise resilience. In this context, it is cr…
Certifying measurement incompatibility in prepare-and-measure and Bell scenarios
Sophie Egelhaaf, Jef Pauwels, Marco Túlio Quintino +1
We consider the problem of certifying measurement incompatibility in a prepare-and-measure (PM) scenario. We present different families of sets of qubit measurements which are inco…
Compressing continuous variable quantum measurements
Pauli Jokinen, Sophie Egelhaaf, Juha-Pekka Pellonpää +1
We generalize the notion of joint measurability to continuous variable systems by extending a recently introduced compression algorithm of quantum measurements to this realm. The e…
