Bookmark or Share- Quantum Physics ForumQuantum physics, or quantum mechanics, is a branch of physics that explores the behavior of matter and energy at the smallest scales, where classical physics principles break down.
- What Planck Length Is and It’s Common Misconceptions - Physics ForumsThe Planck length is an extremely small distance constructed from physical constants. Many misconceptions generally overstate its physical significance, stating that it’s the inherent pixel size of the universe.
- Rotations in Bloch Sphere about an arbitrary axis - Physics ForumsA rotation in the Bloch sphere is a unitary transformation that represents a change in the state of a qubit. It involves rotating the state vector of the qubit around the surface of the sphere, while keeping the length of the vector constant. Rotations can be performed about any axis on the sphere, allowing for a wide range of transformations.
- Understanding Z2 Symmetry in Models - Physics ForumsEven simple, [itex]\mathbb{Z}_2[/itex] refers to a group, namely that of additon mod 2. It only has two elements, the identity and element a, which satisfies a^2 = 1.
- A new realistic stochastic interpretation of Quantum MechanicsIt would be really helpful if Barandes just gave a course solving an example with a single qubit and then and two entangled qubit example. His formalism seems very general, it does not depend on fundamental objects being qubit, particles or fields, and the non-classicality is encoded in his indivisibility.
