BP decoders for qLDPC codes
Do BP (BP-OSD, BP-LSD) decoders process 3-dimensional graphs of a simple noise model, where the third dimension is the time dimension, like how the MWPM decoder works for surface codes? Is there a ...

Applying 2-qubit noise to a multi qubit system using local operations in Python
I am trying to create a simulation of 2-qubit dephasing noise that acts on the first two qubits of a multi qubit system. I would like to do this locally rather than expanding my kraus operators into $...

Implementing Noise in Pennylane (using qiskit.aer)
I want to implement noise in Pennylane using qiskit as a plug-in. I found this tutorial from Pennylane. But, when testing it the bit-flip error seems to have no effect at all.
Here, I made some slight ...

How to turn a 'term' in a QuantumError into a QuantumError?
A QuantumError class may have many terms, and we can use .error_term(position) to have a look at each term. But it returns a list instead of another QuantumError ...

How to intentionally add noise to a Qiskit circuit?
I am attempting to intentionally add noise to my qiskit circuit by applying n-pairs of CNOT gates. The effect of this should be to yield the same result of my baseline (no pairs of CNOT gates applied) ...
