从量子比特和作用到Pauli-Schroedinger方程

From qubits and actions to the Pauli-Schroedinger equation

Salomon S. Mizrahi

摘要:

在这里,我表明,一个经典的或量子比特状态加上一个简单的操作,一个行动,是足够的成分,以获得一个量子动力学方程,规则的顺序变化的状态。然后,通过假设一个自由移动的大质量粒子是量子比特载体,发现粒子在物理空间中的位置和量子比特状态都根据Pauli-Schroedinger方程随时间变化。因此,这种方法提出了以下猜想:因为它携带一个量子比特的信息,粒子运动的描述受制于内部自由度的存在。它不得不不再用经典的方法来描述,而是用波函数来描述。我还简要地讨论了量子比特方面的狄拉克方程。

英文摘要:

Here I show that a classical or quantum bit state plus one simple operation, an action, are sufficient ingredients to derive a quantum dynamical equation that rules the sequential changes of the state. Then, by assuming that a freely moving massive particle is the qubit carrier, it is found that both, the particle position in physical space and the qubit state, change in time according to the Pauli-Schroedinger equation. So, this approach suggests the following conjecture: because it carries one qubit of information the particle motion has its description enslaved by the very existence of the internal degree of freedom. It is compelled to be no more described classically but by a wavefunction. I also briefly discuss the Dirac equation in terms of qubits.
