Unitary time evolution
... This simple result has many profound consequences. For one, the state |ψi of a system is not an observable. Given a quantum system, there is no way to tell in what state |ψi it was prepared. If the state |ψi is known, the state can be “copied” by preparing another system. But it is impossible to co ...

... The previous example involved essentially just one particle, the car. The wall was fixed there as a device for exerting a constant force during the collision. A more complex example can be studied when two particles collide. We first make the approximation that the two particles are subjected to no ...

Thus, small variations in the trajectory of the order ε that keep its endpoints fixed, lead to variations in the action of the order ε2 . Remark 3.6.

Introduction To Quantum Computing
... Threshold Theorem Our entire discussion so far has been on “perfect” quantum gates, but of course they are not perfect. Various “threshold theorems” have suggested that we need 10^4 to 10^6 gates in less than the decoherence time in order to apply quantum error correction (QEC). QEC is a big enough ...
