Sombrero Adiabatic Quantum Computation
... Why starting with an initial guess instead of uniform superposition? In addition to random choices for the initial guess (a good idea if less computational power is to be invested), there are many ways to make an educated guess of a solution: 1) One could use physical intuition or constraints impose ...
