- Abstract: Engineering vector spatial modes of photons is an important approach for
manipulating high-dimension photonic states in various quantum optical
experiments. In this work, we demonstrate generation of heralded single photons
with well-defined vector spatial modes by using a self-locking polarizing
interferometer comprising a spatial light modulator. Specifically, it is shown
that, by carefully tailoring and compensating spatial and temporal amplitudes
of manipulated photons, one can exactly convert ultrafast single photons into
desired spin-orbit states with extremely high purity. This compact and robust
device provides a versatile way for not only generation, but also manipulation
and characterization of arbitrary photonic spin-orbit states.

Quantum networks and distributed quantum computers rely on entanglement generation between photons and long-lived quantum memories.
Here, we maximize the efficiency for the detection of hybrid entanglement between a nuclear spin qubit in diamond with a photonic time-bin qubit.
Our results thus pave the way for the future high-performance quantum networks.

We investigate coherent single-photon transport in a waveguide quantum electrodynamics system containing multiple giant atoms.
We find that the non-dipole effects of giant atoms can strongly manipulate several types of collective properties of the output fields.
We propose to probe the topological states of a chain of braided giant atoms by using photon scattering spectra.

A laser beam is shaped by a voltage-controlled spin-to-orbital angular momentum converter q-plate device.
Such a beam is then used as pump in a spontaneous parametric downconversion (SPDC) photon-pair source.
We demonstrate the full pump to heralded single photon transfer of the intensity/phase distributions, as well as of the vector polarization structure.

We demonstrate the control of giant polarisation rotations induced by a single electron spin.
We find that the polarisation state of the reflected photons can be manipulated in most of the Poincar'e sphere, through controlled spin-induced rotations.
This control allows the operation of spin-photon interfaces in various configurations, including at zero or low magnetic fields.

We show how time-resolved detection of non-ideal photons can be used to improve the fidelity of an entangling operation and to mitigate the reduction of computational complexity in boson sampling experiments.

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.
