Abstract

. We demonstrate experimentally that acousto-optic diffraction by a shear acoustic wave propagating in fused silica can transform linear or circular polarization states into their orthogonal counterparts. It is also shown that a corresponding acousto-optic cell with a shear acoustic wave propagating in a vitreous medium can be used as a NOT or CNOT gate. The advantage of our method is a possibility for spatial manipulation by qubits via acousto-optic diffraction under condition of changing frequency of the acoustic wave.
玻璃介质中剪切声波声光衍射实现偏振编码量子比特的光量子门
。我们通过实验证明,剪切声波在熔融石英中传播的声光衍射可以将线性或圆偏振态转化为正交偏振态。研究还表明,具有在玻璃介质中传播的剪切声波的相应声光单元可以用作非光门或CNOT门。该方法的优点是可以在声波频率变化的条件下,通过声光衍射实现量子比特的空间操纵。
