In a noncontextual hidden variable model of quantum theory, hidden variables determine
the outcomes of every measurement in a manner that is independent of how the …

In a variant of communication complexity tasks, two or more separated parties cooperate to
compute a function of their local data, using a limited amount of communication. It is known …

Recent days have witnessed significant interests in applying quantum-enhanced techniques
for solving a variety of machine learning tasks. Variational methods that use quantum …

By testing the classical correlation violation between two systems, true random numbers can
be generated and certified without applying classical statistical method. In this work, we …

Since quantum information is continuous, its handling is sometimes surprisingly harder than
the classical counterpart. A typical example is cloning; making a copy of digital information is …

Combinatorial problems are formulated to find optimal designs within a fixed set of
constraints and are commonly found across diverse engineering and scientific domains …

We study random-number-expansion protocols based on the n→ 1 quantum random access
codes (QRACs). We consider them in the semi-device-independent scenario where the …

Random access coding is an information task that has been extensively studied and found
many applications in quantum information. In this scenario, Alice receives an n-bit string x …

We consider a communication method, where the sender encodes n classical bits into 1
qubit and sends it to the receiver who performs a certain measurement depending on which …

It is one of the peculiar features of quantum physics that some sets of measurements are
incompatible in the sense that they cannot be performed simultaneously. Incompatibility is …
