Manipulating spectral entanglement by complex temporal phase modulation

Operation co-funded by EU cohesion policy (European Regional Development Fund (ERDF)) under the programme Smart growth - PL - ERDF (2014PL16RFOP001), managing authority: Ministerstwo obsługujące ministra właściwego ds. rozwoju regionalnego. The source names no beneficiary for this operation. Location: Trójmiejski (NUTS PL633); Poland. Budget: total eligible expenditure EUR 167,451.92; EU co-financing EUR 167,451.92 (co-financing rate 100%), as stated by the source. Runs 2016-12-01 to 2018-12-31. Source: Kohesio, EU cohesion policy projects managed by national and regional authorities (not CORDIS); selected because its summary names quantum technology. Summary from Kohesio (English machine translation by the source): Quantum entanglement manifests itself in the strongest possible correlations between two physical systems. Entanglement between photons forms the basis of ultimately secure cryptographic key distribution protocols – quantum key distribution (QKD). Furthermore the field of quantum information processing (QIP), which holds promise to revolutionise computation and metrology, relies crucially on entanglement. Out of the photon’s degrees of freedom the spectral-temporal is the most promising, yet the least explored in the context of QIP. Its assets are high dimensionality and compatibility with integrated optics, however manipulating spectral-temporal entanglement in a low-loss, low-noise manner is challenging. Here we will use latest advances in fast electro-optic phase modulation techniques to perform significant modifications of the quantum state of spectrally entangled photon pairs. In particular we will investigate their use for highly efficient spectrally-encoded QKD.
