Non-classical Semiconductor Photon Sources Enhancing the Performance of Classical Target Detection Systems
Haoyu He, Daniel Giovannini, Han Liu +3
We demonstrate and analyze how deploying non-classical intensity correlations obtained from a monolithic semiconductor quantum photon source can enhance classical target detection…
Enhancing LIDAR performance metrics using continuous-wave photon-pair sources
Han Liu, Daniel Giovannini, Haoyu He +4
In order to enhance LIDAR performance metrics such as target detection sensitivity, noise resilience and ranging accuracy, we exploit the strong temporal correlation within the pho…
Measuring the phase velocity of twisted wavefronts
Grace Richard, Holly Lay, Daniel Giovannini +3
Traditionally one defines the speed of a wave as a property of the medium. Recent studies in photonics have challenged this idea, indicating that spatial shaping of the optical wav…
Coherent absorption of N00N states
Thomas Roger, Sara Restuccia, Ashley Lyons +5
Recent results in deeply subwavelength thickness films demonstrated coherent control and logical gate operations with both classical and single photon light sources. However, quant…
Photons that travel in free space slower than the speed of light
Daniel Giovannini, Jacquiline Romero, Vaclav Potocek +5
That the speed of light in free space is constant is a cornerstone of modern physics. However, light beams have finite transverse size, which leads to a modification of their wavev…
Higher-dimensional orbital angular momentum based quantum key distribution with mutually unbiased bases
Mhlambululi Mafu, Angela Dudley, Sandeep Goyal +7
We present an experimental study of higher-dimensional quantum key distribution protocols based on mutually unbiased bases, implemented by means of photons carrying orbital angular…
Tailored two-photon correlation and fair-sampling: a cautionary tale
Jacquiline Romero, Daniel Giovannini, Daniel Tasca +2
We demonstrate an experimental test of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality which seemingly exhibits correlations beyond the limits imposed by quantum mechanics. I…
Characterization of high-dimensional entangled systems via mutually unbiased measurements
D. Giovannini, J. Romero, J. Leach +3
Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems…
Increasing the dimension in high-dimensional two-photon orbital angular momentum entanglement
J. Romero, D. Giovannini, S. Franke-Anold +2
Any practical experiment utilising the innate D-dimensional entanglement of the orbital angular momentum (OAM) state space of photons is subject to the modal capacity of the detect…
Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks
D. Giovannini, F. M. Miatto, J. Romero +3
The Shannon dimensionality of orbital angular momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers. We…
Bounds and optimisation of orbital angular momentum bandwidths within parametric down-conversion systems
F. M. Miatto, D. Giovannini, J. Romero +3
The measurement of high-dimensional entangled states of orbital angular momentum prepared by spontaneous parametric down-conversion can be considered in two separate stages: a gene…
Resilience of orbital angular momentum qubits and effects on hybrid entanglement
Daniele Giovannini, Eleonora Nagali, Lorenzo Marrucci +1
The orbital angular momentum of light (OAM) provides a promising approach for the implementation of multidimensional states (qudits) for quantum information purposes. In order to c…
Experimental optimal cloning of four-dimensional quantum states of photons
Eleonora Nagali, Daniele Giovannini, Lorenzo Marrucci +3
Optimal quantum cloning is the process of making one or more copies of an arbitrary unknown input quantum state with the highest possible fidelity. All reported demonstrations of q…
