Indefinite Causal Structures on an Integrated Silicon Platform for Applications in Quantum Computing

Objective

Quantum computation achieves a speed-up by placing quantum bits (qubits) in superpositions of different states. However, it has recently been appreciated that quantum mechanics allows one to superimpose not only states but also operations. Furthermore, coherently controlling the operation order with a quantum system enables task completion with fewer operations than any known quantum algorithm. This striking and new way to manipulate the information has not been technologically exploited yet because it requires coherently controlling and simultaneously manipulating high-dimensional quantum systems and multiple degrees of freedom. However, recent progress on Silicon Photonics allows the generation and manipulation of photonic high-dimensional quantum states in the frequency domain fostering the implementation of new complex quantum architectures.
The purpose of this project is to create high-dimensional quantum systems with superposition of operation orders exploiting a multi-color Si photon-pair source. The unique combination of expertise of the experienced researcher and host institution offer all the ingredients to significantly contribute to the transition to a new era in quantum computing where information is processed with indefinite operation order. The project will allow us to scale up superposition of operation orders in order to solve computational problems, and thus to contribute to the transition of the field from fundamental physics to application-oriented research.

Fields of science (EuroSciVoc)

CORDIS classifies projects with EuroSciVoc, a multilingual taxonomy of fields of science, through a semi-automatic process based on NLP techniques. See: https://op.europa.eu/en/web/eu-vocabularies/euroscivoc.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

MSCA-IF-EF-ST - Standard EF

Coordinator

CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
