Optimal Creation of Entanglement Using a Two--Qubit Gate
B. Kraus, J. I. Cirac
We consider a general unitary operator acting on two qubits in a product state. We find the conditions such that the state of the qubits after the action is as entangled as possibl…

Entangling operations and their implementation using a small amount of entanglement
J. I. Cirac, W. Dür, B. Kraus +1
We study when a physical operation can produce entanglement between two systems initially disentangled. The formalism we develop allows to show that one can perform certain non-loc…

Separability and distillability in composite quantum systems -a primer-
M. Lewenstein, D. Bruss, J. I. Cirac +5
Quantum mechanics is already 100 years old, but remains alive and full of challenging open problems. On one hand, the problems encountered at the frontiers of modern theoretical ph…
