Randomizing quantum states: Constructions and applications
Patrick Hayden, Debbie Leung, Peter W. Shor +1
The construction of a perfectly secure private quantum channel in dimension d is known to require 2 log d shared random key bits between the sender and receiver. We show that if on…
Remote preparation of quantum states
Charles H. Bennett, Patrick Hayden, Debbie W. Leung +2
Remote state preparation is the variant of quantum state teleportation in which the sender knows the quantum state to be communicated. The original paper introducing teleportation…
Distillation of secret key and entanglement from quantum states
Igor Devetak, Andreas Winter
We study and solve the problem of distilling secret key from quantum states representing correlation between two parties (Alice and Bob) and an eavesdropper (Eve) via one-way publi…
Commitment Capacity of Discrete Memoryless Channels
Andreas Winter, Anderson C. A. Nascimento, Hideki Imai
In extension of the bit commitment task and following work initiated by Crepeau and Kilian, we introduce and solve the problem of characterising the optimal rate at which a discret…
