Universal superposition codes: capacity regions of compound quantum broadcast channel with confidential messages
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We derive universal codes for transmission of broadcast and confidential messages over classical-quantum-quantum and fully quantum channels. These codes are robust to channel uncer…
Simultaneous transmission of classical and quantum information under channel uncertainty and jamming attacks
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We derive universal codes for simultaneous transmission of classical messages and entanglement through quantum channels, possibly under attack of a malignant third party. These cod…
Universal random codes: Capacity regions of the compound quantum multiple-access channel with one classical and one quantum sender
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We consider the compound memoryless quantum multiple-access channel (QMAC) with two sending terminals. In this model, the transmission is governed by the memoryless extensions of a…
Randomness cost of symmetric twirling
Holger Boche, Gisbert Janßen, Sajad Saeedinaeeni
We study random unitary channels which reproduce the action of the twirling channel corresponding to the representation of the symmetric groupon an n-fold tensor product. We derive…
