How the real IBM quantum computers apply arbitrary Rz(θ) gate rotation? [closed]
I want to ask the following questions:
(1) The basis gate set of IBM quantum computers is { Id, Rz(θ),√X, X, CNOT, reset}. Somebody said that IBM didn’t really apply Rz(θ) gate on the machine. The ...

how to go from matrix to tableau to circuit in qiskit or stim
I'm working with QECC using a non-python based platform. I'd like to move the results into python to do calculations that are better handled by packages like qiskit or stim. So the output of the non-...

Get result measurement into a circuit with Qiskit
I'm trying to implement the three qubit bit flip code in Qiskit.
Therefore, I need to get the result of a measure of two ancilla qubits, to deduce which gate I need to use do recover my logical qubit....

How to create the logical $|0_L\rangle$ state for the Steane's 7-qubit code?
I don't know how to prepare using Qiskit the following state in order to implement a Steane's 7-qubit code circuit (I omit the normalization factor):
\begin{align*} |0_L\rangle =&|0000000\rangle+|...

Is it possible to implement c_if statement based on a measurement in a single specified classical bit in qiskit?
I'm trying to write a 1-bit teleportation error correction code and there is one part in it where I need to add a gate that's dependent on a measurement from earlier in the circuit. The measurement ...

Specifying qubits to achieve measurement error mitigation on Qiskit
I'm learning how to do error mitigation on Qiskit as my experiment result differs from the simulated result. I read the tutorial here, but I have some questions about it. If I have understood it ...

How to implement fault tolerant cat state construction with qiskit?
I want to build a fault-tolerant error correction gadget in qiskit. As a part of that, I want to construct cat states (for the syndrome measurements) in a fault-tolerant way.
One way to do this, is to ...

Applying a projector to a qubit in a qiskit circuit
I'd like to be able to apply $|0 \rangle \langle 0|$ to project a qubit to the state $|0 \rangle$ in the middle of qiskit circuit (see, for example, the attached circuit).
I wonder if, in general, ...
