Computational Monogamy of Entanglement and Non-Interactive Quantum Key Distribution
Quantum key distribution QKD enables Alice and Bob to exchange a secret key over a public, untrusted quantum channel. Compared to classical key exchange, QKD achieves everlasting security: after the protocol execution the key is secure against adversaries that can do unbounded computations. On th...
Probeless Vs Probe-Based Variable-Strength Eavesdropping in Quantum Key Distribution
Quantum key distribution QKD is a provably secure way of generating a secret key, which can later be used for encoding and decoding information. In this paper we analyze the effects of an eavesdropper's variable-strength measurements on QKD. Two types of measurements have been considered: i a...
On the Limitations of Pseudorandom Unitaries
Pseudorandom unitaries PRUs, one of the key quantum pseudorandom notions, are efficiently computable unitaries that are computationally indistinguishable from Haar random unitaries. While there is evidence to believe that PRUs are weaker than one-way functions, so far its relationship with other...
