Quantum information with restricted resources: classic simulation, extensions to universality and applications to cryptography and sensing

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 166,651.64; EU co-financing EUR 166,651.64 (co-financing rate 100%), as stated by the source. Runs 2017-06-01 to 2019-09-30.

Summary from Kohesio (English machine translation by the source): Quantum effects allow to efficiently perform numerous tasks that are either impossible or very difficult to realise by classical means. The main objective of this project is to study quantum-information processing under the restrictions on resources that are allowed to be used. Such restrictions arise from the difficulty to implement in practice the most general quantum-information protocols. We will investigate quantum processes that are effectively-classically simulable and as such do not offer any quantum advantage. On the other hand we will investigate what additional resources promote these restricted theories to universality, revealing their full quantum power. We will focus on experimentally-realistic restricted theories based on linear optical transformations in fermionic and Bosonic systems as well as on the restrictions that practical aspects impose on realisable quantum measurements. These general investigations will be applied to quantum sensing and quantum cryptography.
