Thus different wavelength light can be achieved by preparing samples of quantum dots with varying sizes. Many quantum dots ...

Factoring 51 and 85 with 8 qubits
... presented here should be considered as such. In our opinion a genuine implementation should use no knowledge of the value of the order r—including whether or not it is a power of two—because the objective of the quantum stage of the algorithm is to calculate r. Therefore we do not regard the factori ...
