Coherent temporal filtering of multimode parametric down-conversion using a quantum pulse gate
Abhinandan Bhattacharjee, Patrick Folge, Laura Serino +3
Spectrally pure and indistinguishable single photons are essential for quantum network platforms, where high-visibility interference underpins many quantum information protocols. H…
A high-performance quantum pulse gate in thin-film lithium niobate
Silia Babel, Alejandra Alarcón, Laura Serino +10
In this work, we demonstrate a quantum pulse gate (QPG) in thin-film lithium niobate. QPGs enable the selective manipulation and detection of temporal modes of quantum light and fo…
Generalised quantum interference
Sebastian Malewicz, Laura Serino, Marcelo P. de Almeida +6
Hong-Ou-Mandel interference is one of the clearest signatures of quantum behaviour: two identical photons meeting at a beam splitter always leave together. Here we demonstrate that…
Quantum-limited detection of arrival time and carrier frequency of time-dependent signals
Patrick Folge, Laura Serino, Ladislav Mišta +4
Precise measurements of both the arrival time and carrier frequency of light pulses are essential for time-frequency-encoded quantum technologies. Quantum mechanics, however, impos…
Observing High-dimensional Bell Inequality Violations using Multi-Outcome Spectral Measurements
Kiki Dekkers, Laura Serino, Nicola DAlessandro +5
Violation of Bell inequalities is an essential requirement for many quantum information and communication protocols. In high-dimensional systems, Bell inequality tests face the cha…
Experimental entropic uncertainty relations in dimensions three to five
Laura Serino, Giovanni Chesi, Benjamin Brecht +3
We provide experimental validation of tight entropic uncertainty relations for the Shannon entropies of observables with mutually unbiased eigenstates in high dimensions. In partic…
Frequency-bin interferometry for reconstructing electric fields with low intensity
Abhinandan Bhattacharjee, Laura Serino, Patrick Folge +2
Ultrafast single-photon pulses with tailored time-frequency properties are highly attractive for quantum information science, offering high-dimensional encoding and compatibility w…
Self-guided tomography of time-frequency qudits
Laura Serino, Markus Rambach, Benjamin Brecht +2
High-dimensional time-frequency encodings have the potential to significantly advance quantum information science; however, practical applications require precise knowledge of the…
Programmable time-frequency mode-sorting of single photons with a multi-output quantum pulse gate
Laura Serino, Christof Eigner, Benjamin Brecht +1
We demonstrate a high-dimensional mode-sorter for single photons based on a multi-output quantum pulse gate, which we can program to switch between different temporal-mode encoding…
Pulse characterization at the single-photon level through chronocyclic -function measurements
Abhinandan Bhattacharjee, Patrick Folge, Laura Serino +4
The characterization of the complex spectral amplitude that is, the spectrum and spectral phase, of single-photon-level light fields is a crucial capability for modern photonic qua…
Orchestrating time and color: a programmable source of high-dimensional entanglement
Laura Serino, Werner Ridder, Abhinandan Bhattacharjee +3
High-dimensional encodings based on temporal modes (TMs) of photonic quantum states provide the foundations for a highly versatile and efficient quantum information science (QIS) f…
Complementarity-based complementarity: the choice of mutually unbiased observables shapes quantum uncertainty relations
Laura Serino, Giovanni Chesi, Benjamin Brecht +3
Quantum uncertainty relations impose fundamental limits on the joint knowledge that can be acquired from complementary observables: perfect knowledge of a quantum state in one basi…
