Macroscopically nonlocal quantum correlations
Miguel Gallego, Borivoje Dakić
It is usually believed that coarse-graining of quantum correlations leads to classical correlations in the macroscopic limit. Such a principle, known as macroscopic locality, has b…
Fourier Transform of the Orbital Angular Momentum of a Single Photon
Jaroslav Kysela, Xiaoqin Gao, Borivoje Dakić
Optical networks implementing single-qudit quantum computation gates may exhibit superior properties to those for qubits as each of the optical elements in the network can work in…
Interference as an information-theoretic game
Sebastian Horvat, Borivoje Dakić
The double slit experiment provides a clear demarcation between classical and quantum theory, while multi-slit experiments demarcate quantum and higher-order interference theories.…
Bell's theorem for trajectories
Dragoljub Gočanin, Aleksandra Dimić, Flavio Del Santo +1
In classical theory, the trajectory of a particle is entirely predetermined by the complete set of initial conditions via dynamical laws. Based on this, we formulate a no-go theore…
Quantum enhancement to information acquisition speed
Sebastian Horvat, Borivoje Dakić
The speed of the transmission of a physical signal from a sender to a receiver is limited by the speed of light, regardless of the physical system being classical or quantum. In th…
Selective Quantum State Tomography
Joshua Morris, Borivoje Dakić
We introduce the concept of selective quantum state tomography or SQST, a tomographic scheme that enables a user to estimate arbitrary elements of an unknown quantum state using a…
