Separability of Very Noisy Mixed States and Implications for NMR Quantum Computing

Separability of Very Noisy Mixed States and Implications for NMR Quantum Computing

We give a constructive proof that all mixed states of N qubits in a sufficiently small neighborhood of the maximally mixed state are separable. The construction provides an explicit representation of any such state as a mixture of product states. We give upper and lower bounds on the size of …
