• Abstract summary: We review recent experimental work in the field of spin-mechanics that employ the interaction between trapped particles and electronic spins in the solid state. Our focus is on the theoretical background close to the current experiments, as well as on the experimental limits, that will enable these systems to unleash their full potential.

• Abstract: Controlling the motion of macroscopic oscillators in the quantum regime has been the subject of intense research in recent decades. In this direction, opto-mechanical systems, where the motion of micro-objects is strongly coupled with laser light radiation pressure, have had tremendous success. In particular, the motion of levitating objects can be manipulated at the quantum level thanks to their very high isolation from the environment under ultra-low vacuum conditions. To enter the quantum regime, schemes using single long-lived atomic spins, such as the electronic spin of nitrogen-vacancy (NV) centers in diamond, coupled with levitating mechanical oscillators have been proposed. At the single spin level, they offer the formidable prospect of transferring the spins' inherent quantum nature to the oscillators, with foreseeable far-reaching implications in quantum sensing and tests of quantum mechanics. Adding the spin degrees of freedom to the experimentalists' toolbox would enable access to a very rich playground at the crossroads between condensed matter and atomic physics. We review recent experimental work in the field of spin-mechanics that employ the interaction between trapped particles and electronic spins in the solid state and discuss the challenges ahead. Our focus is on the theoretical background close to the current experiments, as well as on the experimental limits, that, once overcome, will enable these systems to unleash their full potential.

  Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons. We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

  Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors. We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing. Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.

  Single atoms and molecules on surfaces are investigated by physicists, chemists, and material scientists in search of novel electronic and magnetic functionalities.

This review aims to illustrate the essential ingredients that allow the quantum operations of single spins on surfaces.

• Quantum control of nuclear spin qubits in a rapidly rotating diamond [62.997667081978825]
  Nuclear spins in certain solids couple weakly to their environment, making them attractive candidates for quantum information processing and inertial sensing. We demonstrate optical nuclear spin polarization and rapid quantum control of nuclear spins in a diamond physically rotating at $1,$kHz, faster than the nuclear spin coherence time. Our work liberates a previously inaccessible degree of freedom of the NV nuclear spin, unlocking new approaches to quantum control and rotation sensing.

  We propose applying time-dependent photo-emission spectroscopy, an established tool in solid state systems, in cold atom quantum simulators. We show in exact diagonalization simulations of the one-dimensional $t-J$ model that the spinons start to populate previously unoccupied states in an effective band structure. The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

  Tests of quantum mechanics on a macroscopic scale require extreme control over mechanical motion and its decoherence. In this work, we optically levitate a femto-gram dielectric particle in cryogenic free space. We cool its center-of-mass motion by measurement-based feedback to an average occupancy of 0.65 motional quanta, corresponding to a state purity of 43%.
