Generation of qudits and entangled qudits
We propose schemes for the generation of d-level quantum states qudits and quantum entangled states of N qudits by adopting the polarization degree of freedom of photons. Arbitrary qudits can be prepared by putting d−1 identical and independent photons each with a given polarization into a single spatial and temporal mode. Then, by using N such qudits, linear optics, and proper projection measu...
متن کاملTopological phase for entangled two-qubit states.
Entangled states play a crucial role in quantum physics, ranging from fundamental aspects to quantum information processing. We show here that entangled two-qubit states can also be used to characterize unambiguously the subtlety of the SO(3) rotation group topology. The well known two distinct families of path in this group are put in one-to-one correspondence with cyclic evolutions of these e...
متن کاملLocation-Oblivious Data Transfer with Flying Entangled Qudits
We present a simple and practical quantum protocol involving two mistrustful agencies in Minkowski space, which allows Alice to transfer data to Bob at a spacetime location that neither can predict in advance. The location depends on both Alice’s and Bob’s actions. The protocol guarantees unconditionally to Alice that Bob learns the data at a randomly determined location; it guarantees to Bob t...
متن کاملA special simplex in the state space for entangled qudits
Focus is on two parties with Hilbert spaces of dimension d, i.e. “qudits”. In the state space of these two possibly entangled qudits an analogue to the well known tetrahedron with the four qubit Bell states at the vertices is presented. The simplex analogue to this magic tetrahedron includes mixed states. Each of these states appears to each of the two parties as the maximally mixed state. Some...
