Pulse shaping using dispersion-engineered difference frequency generation
Markus Allgaier, Vahid Ansari, John Matthew Donohue +5
The temporal-mode (TM) basis is a prime candidate to perform high-dimensional quantum encoding. Quantum frequency conversion has been employed as a tool to perform tomographic anal…
Experimental Reconstruction of Entanglement Quasiprobabilities
J. Sperling, E. Meyer-Scott, S. Barkhofen +2
We report on the first experimental reconstruction of an entanglement quasiprobability. In contrast to related techniques, the negativities in our distributions are a necessary and…
Tailoring nonlinear processes for quantum optics with pulsed temporal-mode encodings
Vahid Ansari, John M. Donohue, Benjamin Brecht +1
The time-frequency degree of freedom is a powerful resource for implementing high-dimensional quantum information processing. In particular, field-orthogonal pulsed temporal modes…
A two-way photonic interface for linking Sr+ transition at 422 nm to the telecommunications C-band
Thomas A. Wright, Robert J. A. Francis-Jones, Corin B. E. Gawith +7
We report a single-stage bi-directional interface capable of linking Sr+ trapped ion qubits in a long-distance quantum network. Our interface converts photons between the Sr+ emiss…
