Problem 3: Teleporting an Entangled State
... fourth qubit is (I ⊗ X)|ψi. Solution: This calculation is similar to the previous problem. If we carry out the same procedure of relabeling for |v2 i, we end up with |v2 i = (α|01i14 + β|10i14 ) ⊗ |Ψ+ i23 But notice that (I ⊗ X)|ψi = α|01i + β|10i. But this is just the state we have in our expressio ...

Studies of Infinite Two-Dimensional Quantum Lattice
... Determining the properties of quantum many-body systems is a central challenge in modern physics. Being able to determine the macroscopic properties of a system from its microscopic description would hasten progress in many fields of science and technology. However, we currently lack the tools to so ...

Imaging single photons in non-separable states of polarization and spatial mode
... The type of state has been produced classically using a Mach-Zehnder type interferometer.15 That arrangement works well with the (long) coherence lengths of coherent laser sources. However, the tight restrictions of large bandwith sources, as is the case of down-converted photons, adds challenges to ...
