    "abstract": "We investigate the degree to which entanglement survives when a correlated\npair of two-state systems are copied using either local or non-local processes.\nWe show how the copying process degrades the entanglement, due to a residual\ncorrelation between the copied output and the copying machine (itself made of\nqubits).",
