Abstract

Integrated optics forms the platform for powerful applications of quantum communication and computation and solves critical problems in terms of scalability and reliability. The introduction of laser-written photonic structures enables disruptive progress and significantly speeds up the evolution from lab systems to real world applications. QWAD will introduce new functionalities of laser-written photonic waveguides and in a concerted application-driven effort employ them in next-generation quantum optical devices.
Our consortium will target three main outcomes:
1) Fabricate laser-written waveguides in three dimensional structures with the aim to enable full control of the photons' propagation constants and to generate and to manipulate path- and polarization entangled photonic qubits.
2) Implement large integrated circuits to perform scalable quantum logic operations and quantum simulation of many-body dynamics.
3) Design dedicated waveguide structures for fully integrated quantum key exchange and for quantum enhanced sensing in application ready prototypes.

Goals

1) Fabricate laser-written waveguides in highly integrated three dimensional structures to generate and to manipulate both path- and polarization entangled photonic qubits.
2) Implement large integrated circuits to perform scalable quantum logic operations and quantum simulation of many-body dynamics.
3) Design dedicated waveguide structures for fully integrated quantum key exchange and for quantum enhanced sensing in application ready prototypes.
