Sorry for the vague title, what I’m really asking is: when writing a compiler for a quantum DSL, many languages have chosen an imperative or functional host language. Few, if any, have chosen a purely ...

I want to convert a PySCF wavefunction in terms of CIstrings to a representation of a qubit state after Jordan-Wigner transformation of the Hamiltonian.Qiskit-nature keeps the molecular ordering of ...

In this paper, the authors provide a method for constructing qLDPC CSS-T codes. They provide example generator matrices for the binary linear codes $C_1$ and $C_2$ such that $Q(C_1, C_2)$ is a CSS-T ...

Im making a quantum SVM with the quantum kernel using qiskit. Right now, im trying to implement the noise model using the fake provider....

I'm trying to simulate the 1D Ising Model with open periodic boundary conditions using the 2nd order Trotter product for 5 spins sites with J = -1.2 and h =-0.7.$$ H_{Ising} = -J\sum_{i=0}^{spinsites ...

I have been using Stim for a while now. Still, I find it particularly difficult to add non-trivial detectors in Stim (such as the in-place access of the Y-Basis Gidney introduced), and I’m wondering ...

In the paper "Grand Unification of Quantum Algorithms", the following operator is introduced in eqn. (27) of said paper:$$\hat{\Pi }_{\phi } = e^{i\phi (2\hat{\Pi }-\hat{I})}$$The operator ...

I'm working with Stim to analyze error probabilities in quantum error correction circuits, and I'm encountering a confusing aspect regarding the DetectorErrorModel (DEM) output.Consider Steane code ...

I’m trying to connect to IBM Quantum backends using Qiskit Runtime Service.Here’s my code (based on IBM Cloud setup guide):...

I have two problems with the QiskitIntegerComparator: I apply a comparison of a quantum register content with a classical integer in Qiskit and look at the ...

Under the IBM Qiskit v2.X Developer Certification webpage, there are a few courses and resources listed (e.g. the 5 course series from IBM). However, do they fully cover the content tested in the ...

I want to convert a Choi matrix into a corresponding set of Kraus operators.I start out from a numpy array representing the Choi matrix. I convert it to a QuTip Qobj object and then convert it to ...

In digital computer, 0 and 1 is the basic unit of information in memory, that gets processed.Digital computer(having transistors) uses Boolean algebra to process this basic unit of information, where ...

I am trying to install the Chromobius package with the implementation of the Mobius decoder for colour codes. However, I am getting an error in the form of "ERROR: Failed building wheel for ...

I want to perform constant-quantum modular addition: $|x\rangle \mapsto |x + K \bmod R \rangle$ where the input $x$ can be greater than $R$. E.g. For $K=1, R=10$ the input $|11 \rangle$ should map to $...
