英文摘要：
  In quantum computation, series of quantum gates have to be arranged in a predefined sequence that led to a quantum circuit in order to solve a particular problem. What if the sequence of quantum gates is known but both the problem to be solved and the outcome of the so defined quantum circuit remain in the shadow? This is the situation of the stock market. The price time series of a portfolio of stocks are organized in braids that effectively simulate quantum gates in the hypothesis of Ising anyons quantum computational model. Following the prescriptions of Ising anyons model, 1-qubit quantum gates are constructed for portfolio composed of four stocks. Adding two additional stocks at the initial portfolio result in 2-qubits quantum gates and circuits. Hadamard gate, Pauli gates or controlled-Z gate are some of the elementary quantum gates that are identified in the stock market structure. Addition of other pairs of stocks, that eventually represent a market index, like Dow Jones industrial Average, it results in a sequence of n-qubits quantum gates that form a quantum code. Deciphering this mysterious quantum code of the stock market is an issue for future investigations.

中文摘要：
在量子计算中，为了解决一个特定的问题，一系列的量子门必须按预先定义的顺序排列，从而形成一个量子电路。如果量子门的序列是已知的，但待解决的问题和如此定义的量子电路的结果仍处于阴影中，该怎么办？这就是股市的情况。股票投资组合的价格时间序列以辫子的形式组织起来，在伊辛任意子量子计算模型的假设下有效地模拟了量子门。根据Ising-anyons模型的规定，对由四只股票组成的投资组合构造了1量子位量子门。在最初的投资组合中增加两个额外的股票会产生2个量子位的量子门和电路。阿达玛门、保利门或受控Z门是股票市场结构中确定的一些基本量子门。再加上道琼斯工业平均指数（Dow Jones industrial Average）等最终代表市场指数的其他几对股票，就形成了一系列n量子位量子门，形成了一个量子码。破解这个神秘的股票市场量子密码是未来调查的一个问题。
