In quantum physics, the presence of many body problems give rise to large complexity.. due to the exponential size of the hilbert space ML + Quantum Many body Physics = Exciting --- ## Classical CNN ![[Pasted image 20211118002556.png]] ## Quantum NN ![[Pasted image 20211118002638.png]] ![[Pasted image 20211118002705.png]] ![[Pasted image 20211118002725.png]] ![[Pasted image 20211118002808.png]] ![[Pasted image 20211118002825.png]] The weights to be learnt are the parameters to the unitaries.. Input state of N qubits, circuit can be parameterised with Log N parameters Generic N Qubit unitaries would require exponentially many parameters to specify ![[Pasted image 20211118003128.png]] ![[Pasted image 20211118003321.png]] ![[Pasted image 20211118003435.png]]
