Questions tagged [spintronics]

Spintronics (a portmanteau meaning spin transport electronics), also known as spin electronics, is the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. (Wikipedia)

Optical quantum computers VS Superconducting quantum computers VS Electron-spin quantum computers

One of the main problems of superconducting quantum computers is that it is necessary to maintain a very low temperature (near absolute zero). Such cooling is very expensive and complex. Why, then, are Intel, IBM, and many other corporations…

Can the spin-1/2 720° rotation trick apply to qubits?

The idea of a 4π rotation to return an electron to its original state instead of just a single 2π rotation exists - but can this idea apply to qubits or entangled qubits? Are there any use cases for 360° or 720° quantum logic gates?

Why do we need T2 = 2T1, and why is there a factor of 2?

I am trying to understand why we want T2=2T1. After reading several definitions of T1 and T2, I just got really confused about these two constant. Is there a way (mathematically or visually) to explain why we would need T2 = 2T1?

Why does measuring the spin of an atom or electron give results that are considered "peculiar"?

When an atoms/electron spin is measured, why do the measurements of spin always align with the direction of the magnets used while measuring it ? (based on my reading of Chris Bernhardt, Quantum Computing For Everyone). Isn't the reason that when…
