Given $f: \{0, 1\}^n\to\{0, 1\}^m$, how many qubits are needed to implement the oracle $\mat...
Suppose I am given a function $f: \{0, 1\}^n \to \{0, 1\}^m$.
A standard oracle would be of the form $\mathcal{U}|x\rangle|0\rangle^{\otimes m} = |x\rangle|f(x)\rangle$.
I would suspect that this enco …

Can the oracle for $f:\{0,1\}^n \rightarrow \{0,1\}^m$ be implemented with only $n+m$ qubits?
(Part 1: Required ancilla qubits for a given function's oracle)
The question is that given a Boolean function $f:\{0,1\}^n \rightarrow \{0,1\}^m$, how many ancilla qubits are required to build its sta …

How does Qiskit's oracle synthesizer work?
Qiskit provides a phase oracle method that takes a Boolean formula as input and returns a phase oracle circuit for that function as output.
Their source code informed me that the synthesis uses the Tw …
