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…
