Nonlinear engineering of Hong-Ou-Mandel interference with structured light
Simon Darveau, Bienvenu Ndagano
A pair of photons entering a Hong-Ou-Mandel interferometer will bunch or anti-bunch depending on the symmetry of their state in the measured degree of freedom, resulting in constru…
Quantum microscopy based on Hong-Ou-Mandel interference
Bienvenu Ndagano, Hugo Defienne, Dominic Branford +5
Hong-Ou-Mandel (HOM) interference, the bunching of indistinguishable photons at a beam splitter, is a staple of quantum optics and lies at the heart of many quantum sensing approac…
Pixel super-resolution using spatially-entangled photon pairs
Hugo Defienne, Patrick Cameron, Bienvenu Ndagano +7
Pixelation occurs in many imaging systems and limits the spatial resolution of the acquired images. This effect is notably present in quantum imaging experiments with correlated ph…
Imaging entanglement correlations with a single-photon avalanche diode camera
Bienvenu Ndagano, Hugo Defienne, Ashley Lyons +4
Spatial correlations between two photons are the key resource in realising many quantum imaging schemes. Measurement of the bi-photon correlation map is typically performed using s…
Polarization entanglement-enabled quantum holography
Hugo Defienne, Bienvenu Ndagano, Ashley Lyons +1
Holography is a cornerstone characterisation and imaging technique that can be applied to the full electromagnetic spectrum, from X-rays to radio waves or even particles such as ne…
A witness to quantify high-dimensional entanglement
Bienvenu Ndagano, Andrew Forbes
Exploiting photonic high-dimensional entanglement allows one to expand the bandwidth of quantum communication and information processing protocols through increased photon informat…
Observation of local entanglement oscillation in free space
Eileen Otte, Carmelo Rosales-Guzmán, Bienvenu Ndagano +2
It is well known that the entanglement of a quantum state is invariant under local unitary transformations. It dictates, for example, that the degree of entanglement of a photon pa…
Creation and characterization of vector vortex modes for classical and quantum communication
Bienvenu Ndagano, Isaac Nape, Mitchell A. Cox +2
Vector vortex beams are structured states of light that are non-separable in their polarisation and spatial mode, they are eigenmodes of free-space and many fibre systems, and have…
Erasing the orbital angular momentum information of a photon
Isaac Nape, Bienvenu Ndagano, Andrew Forbes
Quantum erasers with paths in the form of physical slits have been studied extensively and proven instrumental in probing wave-particle duality in quantum mechanics. Here we replac…
High-bit-rate quantum key distribution with entangled internal degrees of freedom of photons
Isaac Nape, Bienvenu Ndagano, Benjamin Perez-Garcia +4
Quantum communication over long distances is integral to information security and has been demonstrated in free space and fibre with two-dimensional polarisation states of light. A…
Process tomography of quantum channels using classical light
Bienvenu Ndagano, Benjamin Perez-Garcia, Filippus S. Roux +7
High-dimensional entanglement with spatial modes of light promises increased security and information capacity over quantum channels. Unfortunately, entanglement decays due to pert…
Holographic tool kit for optical communication beyond orbital angular momentum
Abderrahmen Trichili, Carmelo Rosales-Guzmán, Angela Dudley +4
Mode division multiplexing (MDM) is mooted as a technology to address future bandwidth issues, and has been successfully demonstrated in free space using spatial modes with orbital…
Fiber propagation of vector modes
Bienvenu Ndagano, Robert Bruning, Melanie McLaren +2
Here we employ both dynamic and geometric phase control of light to produce radially modulated vector-vortex modes, the natural modes of optical fibers. We then measure these modes…
