Preserving photon qubits in an unknown quantum state with Knill Dynamical Decoupling - Towards an all optical quantum memory
Manish K. Gupta, Erik J. Navarro, Todd A. Moulder +5
The implementation of polarization-based quantum communication is limited by signal loss and decoherence caused by the birefringence of a single-mode fiber. We investigate the Knil…
Quantum optical technologies for metrology, sensing and imaging
Jonathan P. Dowling, Kaushik P. Seshadreesan
Over the past 20 years, bright sources of entangled photons have led to a renaissance in quantum optical interferometry. Optical interferometry has been used to test the foundation…
An introduction to boson-sampling
Bryan T. Gard, Keith R. Motes, Jonathan P. Olson +2
Boson-sampling is a simplified model for quantum computing that may hold the key to implementing the first ever post-classical quantum computer. Boson-sampling is a non-universal q…
Sampling arbitrary photon-added or photon-subtracted squeezed states is in the same complexity class as boson sampling
Jonathan P. Olson, Kaushik P. Seshadreesan, Keith R. Motes +2
Boson sampling is a simple model for non-universal linear optics quantum computing using far fewer physical resources than universal schemes. An input state comprising vacuum and s…
Scalable boson-sampling with time-bin encoding using a loop-based architecture
Keith R. Motes, Alexei Gilchrist, Jonathan P. Dowling +1
We present an architecture for arbitrarily scalable boson-sampling using two nested fiber loops. The architecture has fixed experimental complexity, irrespective of the size of the…
A Quantum Phase Representation of Heisenberg Limits and a Minimally Resourced Quantum Phase Estimator
Scott Roger Shepard, Frederick Ira Moxley, Jonathan P. Dowling
Within the quantum phase representation we derive Heisenberg limits, in closed form, for N00N states and two other classes of states that can perform better in terms of local perfo…
