Quantum mechanics describes the microscopic properties of nature in a regime where classical mechanics no longer applies. It explains phenomena such as the wave-particle duality, quantization of energy, and the uncertainty principle and is generally used in single-body systems. Use the quantum-field-theory tag for the theory of many-body quantum-mechanical systems.

What quantum gates are needed to get the state $|01\rangle+|10\rangle$ from $|00\rangle$?
Let's consider a space of four states $\{|00\rangle, |01\rangle, |10\rangle, |11\rangle\}$. The question is whether exist any operator for which,

Bound States in Dirac Delta Potential
Fox $x\leq 0$ (left region) the potential barrier is infinite. Then particle cannot tunel to that region, so the wave function of the particle is $0$ for $x\leq 0$. In the right region particle can mo …
