  The unveiling of 2D van der Waals magnetism in 2017 ignited a surge of
interest in low-dimensional magnetism. With dimensions reduced, research has
delved into facile electric control of 2D magnetism, high-quality
heterostructure design, and new device functionality. These atomically thin
magnetic materials have spawned a burgeoning field known as 2D spintronics,
holding immense promise for future quantum technologies. In this review, we
comprehensively survey the current advancements in 2D magnet-based quantum
devices, accentuating their role in manifesting exotic properties and enabling
novel functionalities. Topological states, spin torques, voltage control of
magnetic anisotropy, strain engineering, twistronics and designer interface
will be discussed. Furthermore, we offer an outlook to guide their development
in future CMOS and quantum hardware paradigms.
