In quantum information theory, the no-teleportation theorem states that an arbitrary quantum state cannot be converted into a sequence of classical bits (or even an infinite number of such bits); nor can such bits be used to reconstruct the original state, thus "teleporting" it by merely moving classical bits around. Put another way, it states that the unit of quantum information, the qubit, cannot be exactly, precisely converted into classical information bits. This should not be confused with quantum teleportation, which does allow a quantum state to be destroyed in one location, and an exact replica to be created at a different location.

dbo:abstract
  • In quantum information theory, the no-teleportation theorem states that an arbitrary quantum state cannot be converted into a sequence of classical bits (or even an infinite number of such bits); nor can such bits be used to reconstruct the original state, thus "teleporting" it by merely moving classical bits around. Put another way, it states that the unit of quantum information, the qubit, cannot be exactly, precisely converted into classical information bits. This should not be confused with quantum teleportation, which does allow a quantum state to be destroyed in one location, and an exact replica to be created at a different location. In crude terms, the no-teleportation theorem stems from the Heisenberg uncertainty principle and the EPR paradox: although a qubit can be imagined to be a specific direction on the Bloch sphere, that direction cannot be measured precisely, for the general case ; if it could, the results of that measurement would be describable with words, i.e. classical information. The no-teleportation theorem is implied by the no-cloning theorem: if it were possible to convert a qubit into classical bits, then a qubit would be easy to copy (since classical bits are trivially copyable).

  • Dalam teori informasi kuantum, teorema tanpa teleportasi menyatakan bahwa sebuah kondisi kuantum sementara tidak dapat diubah menjadi barisan bit klasik dalam jumlah terhingga maupun tak berhingga, dan bahwa suatu keadaan kuantum tidak dapat direkonstruksi kembali menggunakan bit-bit tersebut, atau sebuah kondisi kuantum tidak dapat “diteleportasi” hanya dengan memindahkan bit klasik yang ada. Dengan kata lain, satuan informasi kuantum, qubit, tidak dapat sepenuhnya diubah ke dalam bit informasi klasik. Perlu diperhatikan bahwa hal ini tidak sama dengan teleportasi kuantum, yang memungkinkan suatu keadaan kuantum dihancurkan di satu titik, dan dibuat replika serupanya di tempat lain. Teorema tanpa teleportasi secara garis besar muncul dari prinsip ketidakpastian Heisenberg dan paradoks EPR: meskipun sebuah qubit dapat digambarkan sebagai sebuah arah pada , arah tersebut tidak dapat dengan pasti, sehingga tidak dapat dideskripsikan secara verbal (informasi klasik). Teorema tanpa teleportasi juga diimplikasikan oleh : jika qubit dapat diubah menjadi bit klasik, maka qubit pasti bisa disalin, karena bit klasik sangat mudah untuk disalin. (in)
