I am using a topological superconductor which is capable of exhibiting nuclear-electronic entanglement being in high magnetic field and low temperature. I am trying it quantified differently for incoherent entanglement and coherent entanglement with phase dependence. Are there any options in Pennylane for incoherent/ coherent entanglement and coherence time? Please help.

Hi @Iffat_Arisa , no. PennyLane works at a higher level and is hardware-agnostic so it doesn’t include details like these.  
You can use pulse programming but unfortunately it doesn’t look like this is what you need.

Would you please advise me which software I need to use for incoherent/ coherent quantum entanglement and coherence time? I prefer Python based software. Please help.

Unfortunately I don’t know any, sorry @Iffat_Arisa.

How can I create low temperature and high magnetic field using Pennylane?

Hi @Iffat_Arisa .

PennyLane is an open-source software framework for quantum machine learning, quantum chemistry, and quantum computing, with the ability to run on quantum hardware and simulators.

It’s not designed for creating magnetic fields.

Feel free to check out [pennylane.ai](https://pennylane.ai) to learn what it can be used for, or explore the [PennyLane Codebook](https://pennylane.ai/codebook/) to learn more about quantum computing!
