... quantum algorithms should exist? To me, it seems tied to the idea that a quantum computer could just “try every possible answer in parallel” But that’s not how quantum computing works! You need to choreograph an interference pattern, where the unwanted paths cancel The miracle, I’d say, is that this ...

Chirality is the property of an object to exist as distinguishable mirror
... If we regard a flight, as example, as consisting of a literally infinite number of infinitesimal steps, what exactly is the effect of such step? . Since there is no such thing as a real number infinitesimally greater than another, the continuum is and remains a very natural idea but we cannot charac ...

It is conventional wisdom that a solution to the measurement problem can always be provided if the eigenstate-eigenvalue link is denied, in particular its necessary part.7 But now note that ...

... or 3 qubits, and is the identity on all the other qubits. Why do we need to assume this? Because physical interactions are local. To work with this constraint, we want a universal set of quantum gates that we can use to build more complex circuits, just like AND, OR, and NOT in classical computers. ...
