Description

Hi there,

Sorry for the noob question.

Is is possible to define multi qubit noise channels and use tfq to do noisy training?

My work flow is similar to that of the tutorials with noise, but instead I'm trying to define the channel

cirq.asymmetric_depolarize(error_probabilities={'XX': 0.1})

This throws errors which vanish upon removing this channel.

Thanks!

Max

Research direction

Start by reproducing the noisy-training tutorial workflow with TensorFlow Quantum and the Cirq asymmetric_depolarize channel using the reported XX error probability. Compare the behavior with and without that channel, then determine whether multi-qubit channels are supported; done means the error or supported usage is clearly documented and verified.
