    Diamonds, one of the hardest materials on Earth, are so strong that they can protect fragile quantum states that would otherwise survive only in a vacuum or at ultra-cold temperatures. Engineers are mastering the art of growing diamonds with special properties and detecting their quantum spins — opening up a range of sensing applications in the life sciences and elsewhere.
