Can simulations of a quantum algorithm on a classical computer out-perform a classical algorithm?
Has it ever been shown that simulation of a quantum algorithm (e.g., using PyQuil or something?) on a classical computer has out-performed a purely classical algorithm? From what I can tell the ...

Randomized Benchmarking Circuit Generation in pyquil
The task at hand is to generate randomized benchmarking circuits using a native gate set (e.g. x, y, and iswap) in the easiest way possible.
Have been using qiskit for this purpose but it appears that ...

How to set different Backend Layouts in TKET and pyQuil (Quil compiler)?
In Qiskit it is possible to describe a CouplingMap on which a circuit get executed. This helps with testing different Layouts. There are many possibilities in Qiskit on how to do this. Firstly you can ...

Is there a method in pyQuil to create logical boolean gates
is there another way to represent a boolean gate. The straight forward way would be to define a gate my a matrix and then apply this gate to the circuit. What i mean by that? For Example an AND-Gate ...

Where can I find a comprehensive list of gate decompositions used by transpilers?
Does anyone know of a web site, paper etc. that has a list of "gate decompositions" e.g. the kind of decompositions that occur when the transpiler decomposes non-native gates to native gates....

How to create a qubit in an arbitrary state in PyQuil
In PyQuil, a qubit is initialised as $|0\rangle$ by default. Suppose, I want to initialise a qubit in an arbitrary state, say $\frac{1}{\sqrt{3}}|0\rangle+\sqrt{\frac{2}{3}}|1\rangle$. How to do this ...
