Generation of polarization-entangled counter-propagating photons with high orbital angular momentum
Elisabeth Wagner, Mikolaj K. Schmidt, Michael J. Steel +1
Spin and orbital angular momenta of light are attractive resources to harness for encoding, and manipulating information, with applications in various quantum photonic technologies…
Density Classification with Non-Unitary Quantum Cellular Automata
Elisabeth Wagner, Federico Dell'Anna, Ramil Nigmatullin +1
The density classification (DC) task, a computation which maps global density information to local density, is studied using one-dimensional non-unitary quantum cellular automata (…
Information Flow in Non-Unitary Quantum Cellular Automata
Elisabeth Wagner, Ramil Nigmatullin, Alexei Gilchrist +1
The information flow in a quantum system is a fundamental feature of its dynamics. An important class of dynamics are quantum cellular automata (QCA), systems with discrete updates…
Directed percolation in non-unitary quantum cellular automata
Ramil Nigmatullin, Elisabeth Wagner, Gavin K. Brennen
Probabilistic cellular automata (CA) provides a classic framework for studying non-equilibrium statistical physics on a lattices. A notable example is the Domany-Kinzel CA, which h…
