A Hamiltonian for quantum copying
Dima Mozyrsky, Vladimir Privman, Mark Hillery
We derive an explicit Hamiltonian for copying the basis up and down states of a quantum two-state system - a qubit - onto n "copy" qubits initially all prepared in the down state.…

Quantized Fields in a Nonlinear Dielectric Medium: A Microscopic Approach
Mark Hillery, Leonard Mlodinow
Theories which have been used to describe the quantized electromagnetic field interacting with a nonlinear dielectric medium are either phenomenological or derived by quantizing th…

Quantum Copying: Beyond the No-Cloning Theorem
Vladimir Buzek, Mark Hillery
We analyze to what extent it is possible to copy arbitrary states of a two-level quantum system. We show that there exists a "universal quantum copying machine", which approximatel…
