 Quantum devices are often described as a path to a future where sensors can measure the smallest changes in the physical world, and computers can quickly solve problems beyond the capability of modern hardware. Developing these technologies requires the construction of quantum analogues to many familiar electronic systems, such as memory registers that can hold a 1 or 0 during a calculation. Many of these analogues are based on manipulating the direction of an electron's spin. This kind of manipulation is often achieved by exposing the spin to well-controlled external electric or magnetic fields, but electromagnetic technologies require complex setups and external devices to supply the field. The present study improves on these applications by applying an oscillating mechanical strain to a compact diamond structure instead of an electromagnetic field, driving an electron through quick transitions between spin states and sustaining the spin for many dozens of oscillations. The experimental system is based on a single diamond crystal in the shape of a diving board known as a cantilever, which allows strain to be applied and controlled with great efficiency. The necessary spin system is prepared by replacing a carbon atom in the diamond structure with a nitrogen, and then knocking out another nearby carbon to make a vacancy. This nitrogen vacancy defect provides three spin states for a pair of electrons, both up, both down, or one up and one down. Oscillating the cantilever applies a strain that is periodic in time, coupling the states in which both spins align, up or down, and allowing the system's state to be juggled rapidly between both up and both down by mechanically oscillating the cantilever in resonance with the spin. When controlled by electromagnetic fields, this system cannot be driven directly between the both up and both down states, and instead must involve the one up one down state. In the studied system, using the cantilever to drive an oscillation between the up and down states preserves the desired spin state four times longer than the same system without the influence of mechanical strain. Long survival times of this kind are necessary for applications such as quantum memory, where storing a value requires a state with long term stability. The extremely high transition speed of nearly 11 million cycles per second is also notable. This frequency places the system in the strong driving regime, where the cycling frequency associated with the controlled transition is large relative to the energy difference between the states themselves. The achievement of strong mechanical driving for such a long lived system promises even longer lifetimes when combined with refinements that more efficiently couple strain to the nitrogen vacancy spin. The system explored here represents a compact quantum device with a purely mechanical input that relies only on the intrinsic properties of the nitrogen vacancy defect and cantilever to provide rapid transitions between states and a long lifetime. These properties are necessary for the development of future quantum computing and sensing applications, and future refinements of the device should improve the transition rate and coherence time of the spin, potentially placing technological applications on the horizon.
