| Jul 22, 2023 at 5:46 | comment | added | madeel | How could we define the notion of "quantum memory"? Classical memory is defined in terms of states but in the quantum case a state of a qubit is defined as a linear combination of two pure states. So obviously we can't define the memory in terms of quantum states. Any idea how should we proceed further. | |

My naive idea about it is that a classical memory can not exist because of the impossibility to make copies of the entire state of the machine. That doesn't mean that one can't define a "quantum memory" terminology that has different properties from a classical memory. | |

He said "in a classical sense" I think to ask whether or not a quantum computer has externally stored information which is processed by an e.g. CPU. In the currently most promising architecture, there's no CPU/RAM equivalent. The idea is more like an FPGA. | |
| Sep 21, 2015 at 21:31 | comment | added | Norbert Schuch | @CuriousOne Quantum information is not information in a classical sense. Why would you expect to be able to store it in a classical memory? | |
| Sep 21, 2015 at 21:16 | comment | added | CuriousOne | So there really is no memory in a classical sense, then? | |
