Quantum key distribution with realistic heralded single photon sources
Mikolaj Lasota, Rafal Demkowicz-Dobrzanski, Konrad Banaszek
We analyze theoretically performance of four-state quantum key distribution protocols implemented with a realistic heralded single-photon source. The analysis assumes a noisy model…

The elusive Heisenberg limit in quantum enhanced metrology
Rafal Demkowicz-Dobrzanski, Jan Kolodynski, Madalin Guta
We provide efficient and intuitive tools for deriving bounds on achievable precision in quantum enhanced metrology based on the geometry of quantum channels and semi-definite progr…
