In the Deutsch-Jozsa (D-J) problem if we have 120 items, how many samples do we need to take to solve the problem via quantum approach in D-J?We are using Simon's Algorithm for finding a hidden number between 0 and 63.How many qubits are neededAll quantum gates are unitary and reversible. The AND operation in classical computers throws information away as two bits go in and only one comes out, making it impossible to know the information if you wanted to go back.All quantum gates are unitary and reversible. The AND operation in classical computers throws information away as two bits go in and only one comes out, making it impossible to know the information if you wanted to go back. How is AND operation performed in a Quantum Circuit?A.It requires an extra bit therefore it is a 3-qubit function performed by a Toffoli gate.B.It is solved by using three NOT gates and a Z rotation.C.It is performed by rolling the dice with a Hadamard Gate.D.That is one of the operations that cannot be performed in a quantum computer. Many algorithms can't be performed and it would require a classical computer to assist the quantum computer. China as long ago as 2017, demonstrated with their Micius satellite, an ability to send lased entangled photons from outer space to two ground stations at high altitudes in Tibet about 1200km apart. The sent 1000 pairs of entangled photons to these two stations and found that the resultant photons were the opposite of each other far more than by chance, thus demonstrating entanglement and Spooky Action at a Distance 2 . 1. Are the two equivalent: (33 mod 7) and (19 mod 7) 2. If we have a Matrix H in qubit 0, and Matrix X or NOT in qubit 1, then we can calculate the combined unitary matrix by calculating which of the following? 3. All quantum gates are unitary and reversible. The AND operation in classical computers throws information away as two bits go in and only one comes out, making it impossible to know the information if you wanted to go back 4.
