- Abstract summary: We demonstrate a method for determining the three-dimensional location of single atoms in a quantum gas microscopy system.
We show that, when aberrations in the system are carefully calibrated and compensated for, this method can be used to determine an atom's position to within a single lattice site.

- Abstract: We demonstrate a method for determining the three-dimensional location of
single atoms in a quantum gas microscopy system using a phase-only spatial
light modulator to modify the point-spread function of the high-resolution
imaging system. Here, the typical diffracted spot generated by a single atom as
a point source is modified to a double spot that rotates as a function of the
atom's distance from the focal plane of the imaging system. We present and
numerically validate a simple model linking the rotation angle of the
point-spread function with the distance to the focal plane. We show that, when
aberrations in the system are carefully calibrated and compensated for, this
method can be used to determine an atom's position to within a single lattice
site in a single experimental image, extending quantum simulation with
microscopy systems further into the regime of three dimensions.

We develop a Gaussian-decomposition-assisted approach to inline holography, for single-shot, simultaneous measurements of absorption and phase-shift profiles.
The phase-angle readout is not only robust against transition saturation, but also insensitive to atom-number and optical-induced interaction-strength fluctuations.
We demonstrate single-shot 3D field sensing by measuring local light shifts to the atomic array with micrometer spatial resolution.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
