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 consider the task of performing quantum state tomography on ad-level spin qudit, using only measurements of spin projection onto different quantization axes. After introducing a …
We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases …
The temporal evolution of a quantum system can be characterized by quantum process tomography, a complex task that consumes a number of physical resources scaling …
When an informationally complete measurement is not available, the reconstruction of the density operator that describes the state of a quantum system can be obtained, in a reliable …

The quantum analogue of ptychography, a powerful coherent diffractive imaging technique, is a simple method for reconstructing d-dimensional pure states. It relies on measuring …
We present a method to reconstruct pure spatial qudits of arbitrary dimension d, which is based on a point diffraction interferometer. In the proposed scheme, the quantum states are …
Paratelmatobiinae is a Leptodactylidae subfamily composed by tiny endemic frogs from Brazil that inhabit the Cerrado and Atlantic Forest biomes. Currently is composed by 14 …
Ultracold atomic systems are exquisite platforms for studying many-body physics and developing quantum technologies. Alkaline-earth (-like) atoms (AEA) in particular offer …
