    "abstract": "Quantum computation has attracted much attention, among other things, due to\nits potentialities to solve classical NP problems in polynomial time. For this\nreason, there has been a growing interest to build a quantum computer. One of\nthe basic steps is to implement the quantum circuit able to realize a given\nunitary operation. This task has been solved using decomposition of unitary\nmatrices in simpler ones till reach quantum circuits having only single-qubits\nand CNOTs gates. Usually the goal is to find the minimal quantum circuit able\nto solve a given problem. In this paper we go in a different direction. We\npropose a general quantum circuit able to implement any specific quantum\ncircuit by just setting correctly the parameters. In other words, we propose a\nprogrammable quantum circuit. This opens the possibility to construct a real\nquantum computer where several different quantum operations can be realized in\nthe same hardware. The configuration is proposed and its optical implementation\nis discussed.",
