Defining Unique, Redundant, and Synergistic Quantum Information
Sean Ericson, Hailin Wang, S. J. van Enk
We extend the classical ideas of the Partial Information Decomposition (PID) to the quantum domain and quantify unique, redundant, and synergistic quantum information. We show that…
How to Project onto an Arbitrary Single-Photon Wavepacket
Tzula B. Propp, Steven J. van Enk
The time-frequency degree of freedom of the electromagnetic field is the final frontier for single-photon measurements. The temporal and spectral distribution a measurement retrodi…
Testing the context-independence of quantum gates
Andrzej Veitia, Steven J. van Enk
The actual gate performed on, say, a qubit in a quantum computer may depend, not just on the actual laser pulses and voltages we programmed to implement the gate, but on its {\em c…
Exchanging identical particles and topological quantum computing
S. J. van Enk
The phase factor that features in the exchange symmetry for identical spin- fermions or bosons is not simply and automatically equal to the phase factor one can obse…
