Synthetic photonic lattice for single-shot reconstruction of frequency combs
James G. Titchener, Bryn Bell, Kai Wang +3
We formulate theoretically and demonstrate experimentally an all-optical method for reconstruction of the amplitude, phase and coherence of frequency combs from a single-shot measu…
In-line detection and reconstruction of multi-photon quantum states
Kai Wang, Sergey V. Suchkov, James G. Titchener +2
Integrated single-photon detectors open new possibilities for monitoring inside quantum photonic circuits. We present a concept for the in-line measurement of spatially-encoded mul…
Quantum metasurface for multi-photon interference and state reconstruction
Kai Wang, James G. Titchener, Sergey S. Kruk +9
Metasurfaces based on resonant nanophotonic structures have enabled novel types of flat-optics devices often outperforming the capabilities of bulk components, yet these advances r…
Scalable on-chip quantum state tomography
James Titchener, Markus Gräfe, René Heilmann +3
Quantum information systems are on a path to vastly exceed the complexity of any classical device. The number of entangled qubits in quantum devices is rapidly increasing and the i…
Reconfigurable cluster state generation in specially poled nonlinear waveguide arrays
James G. Titchener, Alexander S. Solntsev, Andrey A. Sukhorukov
We present a new approach for generating cluster states on-chip, with the state encoded in the spatial component of the photonic wavefunction. We show that for spatial encoding, a…
Direct characterization of a nonlinear photonic circuit's wave function with laser light
Francesco Lenzini, Alexander N. Poddubny, James Titchener +9
Integrated photonics is a leading platform for quantum technologies including nonclassical state generation \cite{Vergyris:2016-35975:SRP, Solntsev:2014-31007:PRX, Silverstone:2014…
Two-photon tomography using on-chip quantum walks
James Titchener, Alexander Solntsev, Andrey Sukhorukov
We present a conceptual approach to quantum tomography based on first expanding a quantum state across extra degrees of freedom and then exploiting the introduced sparsity to perfo…
Tunable generation of entangled photons in a nonlinear directional coupler
Frank Setzpfandt, Alexander S. Solntsev, James Titchener +6
The on-chip integration of quantum light sources has enabled the realization of complex quantum photonic circuits. However, for the practical implementation of such circuits in qua…
Generation of photons with all-optically reconfigurable entanglement in integrated nonlinear waveguides
James G. Titchener, Alexander S. Solntsev, Andrey A. Sukhorukov
We predict that all-optically reconfigurable generation of photon pairs with tailored spatial entanglement can be realized via spontaneous parametric down-conversion in integrated…
