The power of quantum catalytic local operations
Patryk Lipka-Bartosik, Jessica Bavaresco, Nicolas Brunner +1
A key result in entanglement theory is that the addition of a catalyst dramatically enlarges the set of possible state transformations via local operations and classical communicat…
Device Independent Quantum Key Activation
Bora Ulu, Nicolas Brunner, Mirjam Weilenmann
Device-independent quantum key distribution (DIQKD) allows two distant parties to establish a secret key, based only on the observed Bell nonlocal distribution. It remains however,…
Catalytic Activation of Bell Nonlocality
Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequali…
Certification of quantum correlations and DIQKD at arbitrary distances through routed Bell tests
Pavel Sekatski, Jef Pauwels, Edwin Peter Lobo +2
Transmission loss represents a major obstacle to the device-independent certification of quantum correlations over long distances, limiting applications such as device-independent…
Bell nonlocality in quantum networks with unreliable sources: Loophole-free postelection via self-testing
Sadra Boreiri, Nicolas Brunner, Pavel Sekatski
We discuss Bell nonlocality in quantum networks with unreliable sources. Our main result is a condition on the observed data which ensures that inconclusive events can be safely di…
