In the original paper on magic state distillation https://arxiv.org/pdf/quant-ph/0403025 , the 5-to-1 distillation circuit is used to implement a π/6 phase rotation. Is this distillation protocol, alo…
Xanandus Strawberry fields package for photonic QC is advertised in their website . However, the GitHub project was last changed in 2022 and is archived. The documentation says they are no longer acce…
Consider a Hilbert space of dimension $d^2$ and bipartite entangled states therein. I would like to generate (numerically) a collection of separable pure states that all lie within a sub-space of the …
I was wondering whether anyone who is very familiar with ZX calculus could help me with some understanding and questions I had. It's for a university course so I would love a few hours of tutoring. Le…
Consider a circuit which has measurements which are used for post selection, i.e., at any time the measurements flip, the shot is discarded. Then, after this, the circuit also has measurements used fo…
I am looking for a clarification about the Definition of Deterministic Quantum-Chaos vs. the Copenhagen Route Quantum-Chaos Definition. According with challenges from the mentioned LENR parent paper, …
In a recent paper on Krylov-based error diagnostics for open quantum systems, I proved that the Physical Bridge C_meas(τ) ∝ C_op(τ) holds under arbitrary Markovian (Lindblad) dissipation, verified num…
The issue is the QPU usage time on IBM machines. Let me describe the problem. I have a small circuit to manipulate 3 qubits (it is an optimization problem and I don't think the details are relevant, b…
Let $|\psi\rangle \in (\mathbb{C}^d)^{\otimes n}$ be an $n$ -qudit state. Suppose the stabilizer fidelity of $|\psi\rangle$ (i.e., the maximum fidelity $|\langle \psi | \phi \rangle|^2$ over all $n$ -…
Title Is uncomputing the ancilla after phase kickback strictly necessary in Grover's oracle, or only needed to prevent entanglement from degrading the diffusion step? Background I'm building Grover's …
I am interested in QEC in quantum computer. By using Stim, I tried to correct errors in Steane code. Steane code is equivalent to the Color code in case, num_data_qubits = 7. There is an example code …
I am looking for a tool allowing to easily simulate noisy quantum circuits allowing for post-selection. Clifford only simulator might be enough for my purpose (but I want to know what exists in more g…
