### What is your issue?
Greetings Johnnie!
Hope you are doing well sir. I am dropping by to ask three questions:
1) How to block q sites together?
2) How to implement polar decomposition which w…

The new TEBD feature under QuimbBackend to calculate entropy, schmidt gap, and z-magnetization values, given a qibo circuit containing hamiltonian, is a Work-in-Progress.
Files changed: quimb.py an…

### What is your issue?
I would like to use Quimb as a backend for an MPS-based quantum circuit simulator. When running a circuit such as
```
import quimb.tensor as qtn
import numpy as np
cnot…

### Is your feature request related to a problem?
From looking at the [documentation](https://quimb.readthedocs.io/en/latest/autoapi/quimb/tensor/circuit/index.html#quimb.tensor.circuit.Circuit.giv…

I tried to run the example inside the `doc` file of this repo and got this error
```python
from qibo import Circuit, gates, set_backend
# Set the quimb backend
set_backend(

[TDVP](https://arxiv.org/abs/1408.5056) is very similar in sweeping structure to DMRG and should be easy to implement (essentially with local exponentials rather than local groundstates) and would be …

**Description of the issue**
The `test_notebooks_against_cirq_head[.../quimb/Contract-a-Grid-Circuit.ipynb]` fails mysteriously on the CI after bumping up requirements for compatibility with Python…

### minimization of expectation value
The following minimal example
```
import quimb as qu
import quimb.tensor as qtn
L = 3
Z = qu.pauli('X')
bond_dim = 4
mps = qtn.MPS_rand_state(L, bon…

I've come across some strange behaviour when using `quimb` and `xyzpy` together. Not sure which library would be best to put the issue on, but I've chosen this one. I've not been able to replicate the…

We add the support for the benchmarking of tensor network backend in simulation. First quimb, then cuQuantum.
