Bernstein-Vazirani Gate IBM Q Noise
When running the attached Bernstein-Vazirani gate, on IBM Q, I receive the expected result of "00110" with 26.563% success. I notice that there is a lot of noise in the results and am ...

Does anyone know of Qiskit source code for a Bernstein Vazirani grover's algorithm for N bits? If so please share
I'm just getting started in the space of quantum computing, I've built a 5 qubit program for Bernstein-Vazirani, but am trying to figure out how to go about building an N bit version of Bernstein-...

Speed up in Bernstein-Vazirani algorithm and Gottesman-Knill theorem
The Bernstein-Vazirani problem:
Let $f$ be a function from bit strings of length $n$ to a single bit,
$$f: \{ 0, 1\}^n \to \{0, 1\} $$
thus all input bit strings $x \in \{0,1\}^n$. There exists a ...

What are examples of non-oracular versions of famous oracular problems?
Most quantum algorithms proposed, including Deutsch-Jozsa, Simon's, Bernstein-Vazirani etc, involve querying an oracle. If I understand correctly, the speedups depend on the oracle being efficiently ...

Is the intuition of quantum parallelism always correct?
I recently read in Section 7.5.2 of Quantum Computing: A Gentle Introduction by Eleanor Rieffel and Wolfgang Polak a section in which they criticize the view of quantum parallelism in quantum ...

Deutsch-Jozsa algorithm as a generalization of Bernstein-Vazirani
It is known that both algorithms use the same gates: $H^{\oplus n}U_fH^{\oplus n}$.
After the circuit, the qubits are in the state $\sum_y \left( \sum_x (-1)^{f(x)+xy} \right) |y\rangle $.
In DJ's ...

Is the Bernstein-Vazirani algorithm dependent on the specific behavior of the oracle?
My understanding of the Bernstein-Vazirani algorithm is as follows:
We have a black box oracle with secret string $s$. The black box does
$$f(x) =s\cdot{x}=(\sum_1^n s_i\cdot{x_i})$$
We run each ...
