Pretty-good simulation of all quantum measurements by projective measurements
MichaÅ Kotowski, MichaÅ Oszmaniec
In quantum theory general measurements are described by so-called Positive Operator-Valued Measures (POVMs). We show that in -dimensional quantum systems an application of depol…

Improved simulation of quantum circuits dominated by free fermionic operations
Oliver Reardon-Smith, MichaÅ Oszmaniec, Kamil Korzekwa
We present a classical algorithm for simulating universal quantum circuits composed of "free" nearest-neighbour matchgates or equivalently fermionic-linear-optical (FLO) gates, and…
