1 dzień temu · The state of this one-qubit quantum memory can be manipulated by applying quantum logic gates, analogous to how classical memory can be manipulated with classical logic gates.One important gate for both classical and quantum computation is the NOT gate, which can be represented by a matrix:= (). Mathematically, the application of such a logic gate to a quantum state vector is modelled with ...
