As the photon stream transmitted to the client is the 3D topological lattice generated by the mainframe, interrogation of the quantum channel is unnecessary as the state transmitted is globally known. Additionally, the only classical information sent between mainframe and use ...

Quantum mechanics reality and separability

In this way one is forced to accept a positivistic philosophy in which only reasonings about observations and ~bout mathematical schemes are allowed, while the objective refflity is banished from the scientifiic reasoning ...

Simulating large quantum circuits on a small quantum computer
... |ΦU i = (I ⊗ U )|Φi/ 2 is a quantum encoding of U, i.e., a static way to store a dynamic resource! Given |ΦU i, we can execute U. So |ΦU i is a form of “quantum software” [Pre99, GC99]. In a similar spirit, a mixed state ρ encodes a Hamiltonian that can be executed if given enough copies of ρ [KLL+ ...

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 ...
