Storing Quantum Dynamics in Quantum States: A Stochastic Programmable Gate
Storing Quantum Dynamics in Quantum States: A Stochastic Programmable Gate
We show how to encode quantum dynamics in the state of a quantum system, in such a way that the system can be used to stochastically perform, at a later time, the stored transformation on some other quantum system. The probability of failure decreases exponentially with the number of qubits …
