Check out the following blog post marking the addition of expander code to Qubiter
https://qbnets.wordpress.com/2016/12/01/dumbing-down-a-quantum-language-sequel-1/

When I try to invoke Qubiter_to_IBMqasm2() it fails when there are PHAS gates in the English file.

Do we have a PHAS expander that translates into gates available on IBM etc.? Just like we have expanders for DiagUnitary and Multiplexor...

Stairs circuit is currently defined so that, in its full generality (i.e., where it includes all possible parents for each U(2)), it has as final state, a completely general n-qubit state. The stairs circuit as currently defined uses multi-controlled U(2) gates. Can one replace each U(2) by exp(i*alpha) Ry(beta) for real numbers alpha, beta? Hence reduce from four to two parameters per gate string. This would simplify calculation of derivatives. Would it still produce a completely general n-qubit state at the end?

For the Stairs Circuit, suppose, for instance, that you have 10 qubits (0, 1, 2, ..., 9) and you want to "coalesce" qubits 5 and 6. In a fully connected quantum bayesian network, qubit 5 would have qubits (6, 7, 8, 9) as parents, and qubit 6 would have qubits (7, 8, 9) as parents. By coalescing 5 and 6, we go to a non-fully connected qb net in which 5 and 6 have the same set of parents. For instance, 5 and 6 might both have (8, 9) as parents. Thus, in this example, coalescing qubits 5 and 6 produces a node 5_6 with 4 states (qudit with d=4) and 2 parents, namely qubits (8, 9).

Hello,
Is it possible to handle mid-circuit measurements on Qubiter? Is the energy state collapsed with such an operation?
Thank you.
