B Quantum Entanglement in Practice

Click For Summary
Quantum entanglement is achieved in practice through methods like spontaneous parametric down-conversion (SPDC), which produces entangled photons. Different particles, such as those with varying spin and polarization properties, can be entangled using various techniques tailored to their characteristics. Entanglement is crucial for quantum circuits as it enables complex computations and enhances the efficiency of quantum algorithms. The phenomenon is linked to computational hardness in quantum systems, making it a vital area of research. Understanding these applications is essential for grasping the significance of quantum entanglement in quantum computing.

How is quantum entanglement done in practice for different particles with different properties eg. spin, polarization, etc.? Why is entanglement useful for quantum circuits?

*I am curious about how they are actually entangled and used. I don't know how is entanglement applied in practice so I don't know why people mention it is useful for quantum computing.*

For production of entangled photons see e.g. spontaneous parametric down-conversion (SPDC).

Thread 'Angular Momentum Vector and Its Magnitude'

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
