Add circuit ``to_cirq`` and ``from_cirq`` functionality

3

## Task description Similar to `AbstractCircuit.to_qiskit` method, ultimately we would like to transform tensorcircuit Circuit with cirq Circuit as well. ## Implementation Add functions similar to `qir2qiskit` in https://github.com/tencent-quantum-lab/tensorcircuit/blob/master/tensorcircuit/translation.py. And...

Wired input and output of function "c.amplitude"

3

## Issue Description For a quantum circuit with n qubits, function "c.amplitude" returns the amplitude of a given quantum state. It will work when an n-bit binary string is passed...

PyTorch2.0's jit is still not good enough to support jit in tc

3

## Issue Description Simply replacing ``torch.jit.script`` or ``torch.jit.trace`` with ``backend.jit`` still fail for tc functions Example scripts: ```python @torch.jit.script def f(param): c = tc.Circuit(6) for i in range(5): for j...

Some issues when migrating vqe_h2o.ipynb to use CO2

10

I am trying to migrate [vqe_h2o.ipynb](https://github.com/tencent-quantum-lab/tensorcircuit/blob/master/docs/source/tutorials/vqe_h2o.ipynb) to use `CO2` [carbon dioxide molecule](https://gist.github.com/buttercutter/19cd09def3360f88db509670179fd54c/f48198df7129dcce72979f2d17c84efe82f450f4#file-vqe_co2-ipynb). 1. For `print(fh.terms[((0, 1), (0, 0))])` which is the two-body coefficients, it gives `-36.01932840424451`. When I try to...

Improve the slow complication of MPSCircuit

16

## Issue Description In my tests, MPSCircuits take much longer to get jitted than the same circuits. For example, within 2 minutes for a default-type circuit of 8 qubits, but...

Vmap isn't working when using JAX-based MPSCircuits

3

## Issue Description In the test of #213, I found that the Vmap function isn't working when using JAX-based MPSCircuit. The program is not paralleled and only uses one CPU...
