     "`Tensor networks` are used as an alternate representation for a network of qubits. This representation consists of a network of tensors with connections among them. The `matrix product state` (MPS) is the simplest type of tensor network, where we have a one dimensional set of tensors, with connections between every two consecutive tensors. This representation can be used to represent a system of qubits, where each qubit is represented by one tensor. The MPS structure is often depicted graphically, as follows: \n",

The depth of the circuits is kept constant at 120 gates. The final computation of the circuit is the expectation value of random Pauli gates on 5 random qubits.\n",
