Quantum Multi-Task Learning Architecture for \(T=3\) and \(K=4\). The circuits inside the Grey (\(\hat{U}_s(\varvec{\theta }_s)\)) and Pink boxes (\(\hat{U}_{11}^1(\varvec{\theta }_{11}^1)\), \(\hat{U}_{01}^1(\varvec{\theta }_{01}^1)\), \(\hat{U}^1_{10}(\varvec{\theta }_{10}^1)\), \(\hat{U}^1_{00}(\varvec{\theta }_{00}^1)\)) are applied sequentially for a required number of iterations followed by the SWAP test.
