摘要:

逻辑关系可用逻辑函数表示,量子逻辑关系是可逆的,引入和定义了量子逻辑函数;通过引入辅助量子位,增添量子输出信号的区分位,完成对非可逆逻辑门的改造,使非可逆逻辑门在量子电路中得到可逆实现,并研究了一些有用的非可逆逻辑门的改造方法,给出可实现的优化后的量子电路。

Abstract:

The logical relationship can be described with the Boolean functions. The quantum Boolean function are introduced and defined because quantum logic relationship is reversible. The irreversible logic operations are accomplished in the quantum reversible logic circuits by introducing auxiliary qubits and adding the output signal of quantum bits to distinguish the different bit. Then the irreversible logical gate can be realized in quantum circuits. Also we give the optimized quantum circuit about the irreversible logical gate which can be realized.

Key words: irreversible quantum logical gate, quantum circuit, logical function, quantum logical function, redundancy qubits
