Bell's theorem proves that quantum theory is inconsistent with local physical models. It has
propelled research in the foundations of quantum theory and quantum information science …

Quantum theory is commonly formulated in complex Hilbert spaces. However, the question
of whether complex numbers need to be given a fundamental role in the theory has been …

Complex numbers define the relationship between entities in many situations. A canonical
example would be the off-diagonal terms in a Hamiltonian matrix in quantum physics …

In many studies, it is common to use binary (ie, unweighted) edges to examine networks of
entities that are either adjacent or not adjacent. Researchers have generalized such binary …

Networks composed of independent sources of entangled particles that connect distant
users are a rapidly developing quantum technology and an increasingly promising test-bed …

Pseudorandom quantum states (PRSs) and pseudorandom unitaries (PRUs) possess the
dual nature of being efficiently constructible while appearing completely random to any …

Quantum networks promise unprecedented advantages in information processing and open
up intriguing new opportunities in fundamental research, where network topology and …

We investigate network nonlocality in the triangle scenario when all three parties have no
input and binary outputs. Through an explicit example, we prove that this minimal scenario …

Quantum mechanics is commonly formulated in a complex, rather than real, Hilbert space.
However, whether quantum theory really needs the participation of complex numbers has …

The question of whether complex numbers play a fundamental role in quantum theory has
been debated since the inception of quantum mechanics. Recently, a feasible proposal to …
