Quantum-Guided Emergent Control (QGEC) is a novel approach to control system design that leverages quantum annealing and optimization techniques to induce complex, self-organizing control patterns within systems. Traditional control methods are often static, leading to suboptimal performance. QGEC introduces a dynamic system, guiding control parameters through iterative refinement based on system state, ultimately achieving enhanced resource allocation and feedback loop stability. This paper investigates the theoretical underpinnings and practical implementation of QGEC, demonstrating its potential to surpass current control paradigms in dynamic, complex environments.Quantum-Guided Emergent Control (QGEC) is a novel approach to control system design that leverages quantum annealing and optimization techniques to induce complex, self-organizing control patterns within systems.

Title: Quantum Entanglement Modulation via Stochastic Feedback

Jincheng Zhang

Quantum entanglement, a cornerstone of quantum mechanics, is a profoundly fragile phenomenon, susceptible to decoherence. While classical techniques offer limited control, this paper proposes a novel method for manipulating and stabilizing entangled states using stochastic feedback. We introduce a quantum algorithm that continuously adjusts entanglement parameters based on a probabilistic feedback signal, aiming to mitigate decoherence and enhance fidelity. The core mechanism centers on a dynamically evolving feedback loop that leverages randomness to guide the state's evolution. This approach represents a fundamentally different strategy compared to existing classical control methods, potentially unlocking enhanced quantum communication and computation capabilities.Quantum entanglement, a cornerstone of quantum mechanics, is a profoundly fragile phenomenon, susceptible to decoherence.

We study measurement-induced entanglement and control phase transitions in a quantum and stochastic analog of the Bernoulli map subjected to a classically inspired control protocol. When entangling gates are restricted to the Clifford group, separate entanglement ( ${p}_{\mathrm{ent}}$ ) and control ( ${p}_{\mathrm{ctrl}}$ ) transitions emerge, revealing two distinct universality classes. The control transition has critical exponents $\ensuremath{\nu}$ and $z$ consistent with the classical map (a random walk) while the entanglement transition is revealed to have similar exponents as the measurement-induced phase transition in Clifford hybrid dynamics. This is distinct from the case of generic entangling gates with nonlocal control in the same model, where ${p}_{\mathrm{ent}}={p}_{\mathrm{ctrl}}$ and universality is controlled by the random walk.We study measurement-induced entanglement and control phase transitions in a quantum and stochastic analog of the Bernoulli map subjected to a classically inspired control protocol.
