Summary

• What is new: Achievement of three-way entanglement and optimal two-way nonlocal entanglement from a separable state using a 2D alternate quantum walk and a single-qubit coin.
• Why this is important: Encoding and processing information securely in quantum technology needs improved methods for generating complex entangled states.
• What the research proposes: Using 2D alternate quantum walks with a single-qubit coin to evolve a quantum particle through three degrees of freedom, achieving high levels of three-way and two-way nonlocal entanglement.
• Results: Maximum possible values for three-way entanglement quantified by the $\pi$-tangle and optimal nonlocal two-way entanglement quantified by negativity were achieved.
