Ancillary Gaussian modes activate the potential to witness non-Markovianity
Dario De Santis, Donato Farina, Mohammad Mehboudi +1
We study how the number of employed modes impacts the ability to witness non-Markovian evolutions via correlation backflows in continuous-variable quantum dynamics. We first prove…
Upper bounds on key rates in device-independent quantum key distribution based on convex-combination attacks
Karol Łukanowski, Maria Balanzó-Juandó, Máté Farkas +2
The device-independent framework constitutes the most pragmatic approach to quantum protocols that does not put any trust in their implementations. It requires all claims, about e.…
Three numerical approaches to find mutually unbiased bases using Bell inequalities
Maria Prat Colomer, Luke Mortimer, Irénée Frérot +2
Mutually unbiased bases correspond to highly useful pairs of measurements in quantum information theory. In the smallest composite dimension, six, it is known that between three an…
Quantum networks self-test all entangled states
Ivan Šupić, Joseph Bowles, Marc-Olivier Renou +2
Certifying quantum properties with minimal assumptions is a fundamental problem in quantum information science. Self-testing is a method to infer the underlying physics of a quantu…
Local quantum overlapping tomography
Bruna G. M. Araújo, Márcio M. Taddei, Daniel Cavalcanti +1
Reconstructing the full quantum state of a many-body system requires the estimation of a number of parameters that grows exponentially with system size. Nevertheless, there are sit…
Testing real quantum theory in an optical quantum network
Zheng-Da Li, Ya-Li Mao, Mirjam Weilenmann +12
Quantum theory is commonly formulated in complex Hilbert spaces. However, the question of whether complex numbers need to be given a fundamental role in the theory has been debated…
