Resumo: |
The ability to store information is essential for any computing device. A quantum memory is the quantum realization of a data storage and retrieval device. A probabilistic quantum memory is an associative memory model which stores binary data on a quantum superposition and retrieves the information by calculating the Hamming distance between the input pattern and any other binary patterns stored on the memory. In this work, an experimental evaluation of the probabilistic quantum memory is performed on a noisy quantum device that has only 5 qubits. Universal quantum computers are not yet a reality and the quantum devices that are available at present are noisy and have a small amount of qubits, in addition to having a limited architecture. In this way, in order to perform the implementation of a quantum memory in one of these devices, a hybrid classical-quantum implementation was proposed in this work in the form of a optimized protocol which reduces the number of qubits and quantum operations necessary for the execution of the quantum memory on small-scale quantum devices. Through an experimental evaluation it was verified that the proposed implementation presented the expected functioning of the quantum memory. |
