Efficient and Robust Quantum Key Distribution With Minimal State Tomography
Berthold-Georg Englert, Dagomir Kaszlikowski, Hui Khoon Ng +3
We introduce the Singapore protocol, a qubit protocol for quantum key distribution that is fully tomographic, more efficient than other tomographic protocols, and very robust. Unde…

Quantum tomographic cryptography with Bell diagonal states: non-equivalence of classical and quantum distillation protocols
Dagomir Kaszlikowski, Jenn Yang Lim, D. K. L. Oi +3
We present a generalized tomographic quantum key distribution protocol in which the two parties share a Bell diagonal mixed state of two qubits. We show that if an eavesdropper per…
