For the first time, researchers at Columbia University have observed a quantum fluid, known as the fractional quantum Hall states, in a monolayer 2D semiconductor. This observation demonstrates the excellent intrinsic quality of 2D semiconductors and establishes them as a unique test platform for future applications in quantum computing. The fractional quantum Hall state is a collective phenomenon that comes about when researchers confine electrons to move in a thin two-dimensional plane and subject them to large magnetic fields.
