QUANTIP aims to develop the tools, components and concepts that will enable progress towards large-scale, integrated quantum photonic circuits for the development of advanced quantum systems for the purposes of quantum communications, information processing and metrology. A range of discrete integrated quantum photonic components will be developed and then integrated to form proof-of-principle demonstrators of fully- integrated prototypes, where all major components are integrated onto a single chip.

PICC aims to identify tools for controlling ion crystal as their size is scaled up, develop strategies for implementing quantum dynamics of mesoscopic ion Coulomb crystals in a noisy environment and explore the capability of ion Coulomb crystals as quantum simulators. The targeted breakthrough is a ten fold increase in the number of entangled ions available for quantum operation operations. The long-term vision underlying this proposal is to engineer quantum correlations and entanglement in ion Coulomb crystals in order to exploit them for technological purposes of different kinds.

MINOS is targeting an emerging field in photonics, namely micro- and nano-optomechanical cavities with the aim to exploit opto-mechanical effects to control light-matter interaction.

MIDAS aims to work on noise control allowing high fidelity quantum operations on the entanglement of collective variables which are prerequisites for high precision metrology, weak signal sensing and teleportation near the ultimate quantum limits. The project will explore the feasibility of interfacing UCA and SC quantum storage/readout system. This proposal aims to create a new field of research by merging two previously unrelated classes of quantum systems.

HIP addresses the problem of scaling quantum processors by attempting to build elementary hybrid atom-photon devices and develop the schemes for their integration on platforms capable of being miniaturised and scaled up in functional networks.

HIDEAS aims at exploiting the high-dimensional multimodal entangled quantum states of the optical radiation field to significantly increase the information capacity of quantum communication, quantum imaging and quantum metrology

CORNER aims to develop a general framework for understanding and managing noise effects in quantum information technology with particular attention paid to the previously unexplored area of correlated noise errors that commonly arise in space and/or time especially in large scale operations.
