Quantum resources can improve communication complexity problems (CCPs) beyond their
classical constraints. One quantum approach is to share entanglement and create …

We report the experimental measurement of the winding number in an unitary chiral
quantum walk. Fundamentally, the spin-orbit coupling in discrete time quantum walks is …

We introduce a method to estimate unknown pure d-dimensional quantum states using the
probability distributions associated with only three measurement bases. The measurement …

High-dimensional entanglement is a valuable resource for secure and efficient quantum
information processing. A major challenge for practical use of multidimensional quantum …

High-dimensional quantum information processing has become a mature field of research
with several different approaches being adopted for the encoding of D-dimensional quantum …

Optical phase determination is an important and established tool in diverse fields such as
astronomy, biology, or quantum optics. There is increasing interest in using a lower number …

We present a compact scheme for the generation of high-dimensional states of light
encoded in the transverse linear momentum of photons that carry orbital angular momentum …

It has been recently shown that for quantum systems with dimension d≥ 4 unknown pure
states can be estimated via measurements on five bases only. Here, we study by means of …

We present a tomographic method which requires only 4d− 3 measurement outcomes to
reconstruct any pure quantum state of arbitrary dimension d. Using the proposed scheme …

We present an experimental optical implementation of a parallel-in-time discrete model of
quantum evolution, based on the entanglement between the quantum system and a finite …
