Quantum Spin Liquid (QSL) is one of the most astonishing states of matter which was theoretically predicted decades ago. In such a state the spins appear disordered while they form a novel entanglement, which if harnessed could be used for future technological advancements such as quantum computing. Despite the outpour of activities in pursuit of designing and characterizing perfect QSL candidates, these experimental efforts have proven challenging. In this talk I will review some of these challenges and discuss our recent efforts to overcome them and provide a deeper understanding for this fascinating state of matter.
