• Abstract: We introduce and analyze an active steering protocol designed to target multipartite entangled states. The protocol involves multiple qubits subjected to weak Bell pair measurements with active feedback, where the feedback operations are optimized to maximize the Quantum Fisher Information. Our scheme efficiently reaches a genuinely entangled one-parameter state manifold. Numerical simulations for systems with up to 20 qubits suggest that the protocol is scalable and allows high multipartite entanglement across the system.

  We propose schemes for resource reusability, resource-splitting protocol and unsharp homodyne measurements. We demonstrate the advantage offered by the first scheme in implementing sequential attempts at continuous variable teleportation when the protocol fails in the previous round. We exhibit that, under specific conditions, it is possible to witness the entanglement of a state an arbitrary number of times via a scheme that differs significantly from any protocol proposed for finite dimensional systems.

  We propose active steering protocols for quantum state preparation in quantum circuits. We show that the standard fidelity does not give a useful cost function; instead, successful steering is achieved by including local fidelity terms. numerical simulations suggest that the active steering protocol can reach arbitrarily designated target states.
