- With some extra resources, it becomes possible, and it is exactly the aim of phase kickback.[1]
- Thus the phase kickback is either \(0\) or \(\pi\), which is particularly easy to distinguish since they are eigenstates of \(\sigma_x\).[1]
- This happens because of phase kickback.[2]
- Postdoctoral researcher Ben Criger (QuTech) introduces in this video the concept of quantum phase kickback, which is a powerful tool in extracting information out of your system.[3]
- Many quantum algorithms are based upon the concept of quantum phase kickback.[3]
- This is an example of kickback (or, phase kickback ) which is very important and is used in almost every quantum algorithm.[4]
- The circuit then propagates these errors to the auxiliary qubit using the principle of phase kickback.[5]
- The basic maneuver leading to the phase-estimation algorithm is known as phase kickback.[6]
