A two-component Bose-Einstein condensate can ‘bypass’ the no-cloning theorem

Shouvik Datta

No-cloning theorem in quantum cryptography prevents an eavesdropper from perfectly duplicating any arbitrary quantum state. Here we argue that an experimental scheme to produce a quantum superposition of interacting Bose-Einstein condensates can generate N bosonic clones of any arbitrary single quantum state at large N limit of thermodynamic equilibrium with high fidelity and thus operationally ‘bypass’ the restrictions imposed by the above mentioned theorem. This is possible because quantum statistical nature of this ‘cloning operation’ does not require strict unitary evolution of standard quantum mechanics within a single Hilbert space.No-cloning theorem in quantum cryptography prevents an eavesdropper from perfectly duplicating any arbitrary quantum state.
