Impossibility of Quantum Private Queries
Esther Hänggi, Severin Winkler
Symmetric private information retrieval is a cryptographic task allowing a user to query a database and obtain exactly one entry without revealing to the owner of the database whic…
Lower Bounds for Quantum Secure Function Evaluation Reductions
Esther Hänggi, Severin Winkler
One-sided output secure function evaluation is a cryptographic primitive where the two mutually distrustful players, Alice and Bob, both have a private input to a bivariate functio…
On the Efficiency of Classical and Quantum Secure Function Evaluation
Severin Winkler, Jürg Wullschleger
We provide bounds on the efficiency of secure one-sided output two-party computation of arbitrary finite functions from trusted distributed randomness in the statistical case. From…
Impossibility of Growing Quantum Bit Commitments
Severin Winkler, Marco Tomamichel, Stefan Hengl +1
Quantum key distribution (QKD) is often, more correctly, called key growing. Given a short key as a seed, QKD enables two parties, connected by an insecure quantum channel, to gene…
Bit Commitment from Non-Signaling Correlations
Severin Winkler, Juerg Wullschleger, Stefan Wolf
Central cryptographic functionalities such as encryption, authentication, or secure two-party computation cannot be realized in an information-theoretically secure way from scratch…
Distilling Non-Locality
Manuel Forster, Severin Winkler, Stefan Wolf
Two parts of an entangled quantum state can have a correlation in their joint behavior under measurements that is unexplainable by shared classical information. Such correlations a…
