I am currently working on a project on a higher version of amplitude amplification and for that we want to store the initial state (which will be some sort of superposition) into a QRAM. Now we want to simulate the working of the algorithm and I am supposed to make a QRAM, but most of the papers which use QRAM as a subroutine have not shown implementation, furthermore the bucket brigade Quantum RAM is actually not able to give out a superposition of Quantum States which have been stored into a QRAM.

Ideally we want the QRAM to work something like this,

$$ \sum_{j=0}^{2^q-1} \alpha_j | \text{adr}_j \rangle|0\rangle \xrightarrow{\text{QRAM}} \sum_{j=0}^{2^q-1}\alpha_j |\text{adr}_j\rangle|m_j\rangle $$

Anyone who has any idea which QRAM will be able to query out a superposition of states stored in memory cells, please provide some reference. Any help is greatly appreciated!!

If you are looking for implementations of quantum memories, you can find a few in this QRAM library for Q#. I am not quite sure what you mean by the bucket brigade protocol is not able to readout entangled data, but as far as I understand you can do that with bucket brigade (we used it in this example that implements Grover's algorithm with a bucket brigade QRAM).

I agree with Craig, clarifying with your prof whether you need just read operations (QROM) or read/write (QRAM) is important here.
