We demonstrate a new mechanical transduction platform for individual spin qubits. In our
approach, single micromagnets are trapped using a type-II superconductor in proximity of …

Mechanical systems can be influenced by a wide variety of small forces, ranging from
gravitational to optical, electrical, and magnetic. When mechanical resonators are scaled …

Isolated electronic and nuclear spins in solids are at present being actively explored for
potential quantum-computing applications. Spin degrees of freedom provide an excellent …

We describe a technique that enables a strong coherent coupling between a single
electronic spin qubit associated with a nitrogen-vacancy impurity in diamond and the …

We demonstrate coherent quantum control of a single spin driven by the motion of a
mechanical resonator. The motion of a mechanical resonator is magnetically coupled to the …

Quantum mechanics demands that the act of measurement must affect the measured object.
When a linear amplifier is used to continuously monitor the position of an object, the …

We report on single electronic spins coupled to the motion of mechanical resonators by a
novel mechanism based on crystal strain. Our device consists of single-crystal diamond …

We show that by magnetically trapping a superconducting microsphere close to a quantum
circuit, it is possible to perform ground-state cooling and prepare quantum superpositions of …

Observing and controlling macroscopic quantum systems has long been a driving force in
quantum physics research. In particular, strong coupling between individual quantum …

We propose and demonstrate first steps toward schemes in which the librational mode of
levitating ferromagnets can be strongly coupled to the electronic spin of nitrogen-vacancy …
