How do quantum networks work?

Quantum networks require a synergistic integration of terrestrial infrastructure employing optical fibers and wireless free-space communication technologies.

What is quantum computing?

Quantum computing is the study of a classical computers model of computation. Whereas traditional models of computing such as the Turing machine or Lambda calculus rely on "classical" representations of computational memory, a quantum computation could transform the memory into a quantum superposition of possible classical states.

Can a nuclear spin network be used for quantum simulations?

The ability to characterize large and complex nuclear-spin networks could enable quantum applications, such as quantum simulations of many-body physics. Here the authors develop a high-resolution quantum-sensing method and use it to image a network of 50 nuclear spins surrounding a single NV center in diamond.

What is a quantum neural network (QNN)?

A quantum neural network (QNN) is used to describe a parameterized quantum computational model that is best executed on a quantum computer. This term is often interchangeable with parameterized quantum circuit (PQC).
