Optimised Domain-engineered Crystals for Pure Telecom Photon Sources
Alexander Pickston, Francesco Graffitti, Peter Barrow +4
The ideal photon-pair source for building up multi-qubit states needs to produce indistinguishable photons with high efficiency. Indistinguishability is crucial for minimising erro…
Non-Markovian super-superradiance in a linear chain of up to 100 qubits
Fatih Dinc, Agata M. Brańczyk
We study non-Markovian enhancement effects in the spontaneous emission of a collective excitation in a linear chain of up to 100 qubits coupled to a 1D waveguide. We find that for…
Quantum simulation of Unruh-DeWitt detectors with nonlinear optics
Eugene Adjei, Kevin J. Resch, Agata M. Brańczyk
We propose a method for simulating an Unruh-DeWitt detector, coupled to a 1+1-dimensional massless scalar field, with a suitably-engineered nonlinear interaction. In this…
Direct generation of tailored pulse-mode entanglement
Francesco Graffitti, Peter Barrow, Alexander Pickston +2
Photonic quantum technology increasingly uses frequency encoding to enable higher quantum information density and noise resilience. Pulsed time-frequency modes (TFM) represent a un…
Non-Hermitian engineering for brighter broadband pseudothermal light
Nicolás Quesada, Eugene Adjei, Ramy El-Ganainy +1
We show that non-Hermitian engineering can play a positive role in quantum systems. This is in contrast to the widely accepted notion that optical losses are a foe that must be eli…
Broadband pseudothermal states with tunable spectral coherence generated via nonlinear optics
Nicolás Quesada, Agata M. Brańczyk
It is well known that the reduced state of a two-mode squeezed vacuum state is a thermal state---i.e. a state whose photon-number statistics obey a geometric distribution. More exo…
