Quantum entanglement in the NMR implementation of the Deutsch-Jozsa algorithm [PDF]

open access: yes, 1999
A scheme to execute an n-bit Deutsch-Jozsa (D-J) algorithm using n qubits has been implemented for up to three qubits on an NMR quantum computer. For the one and two bit Deutsch problem, the qubits do not get entangled, hence the NMR implementation is ...
