In this article, we present a simple technique that measures static and microwave field distributions on a mm-scale and with a resolution of approximately 100 micrometer in the vicinity of a superconducting, chip-based microwave guide.

Entanglement correlations between particles constitute one of the most striking phenomena in quantum physics. Many key properties of materials, such as superconductivity or magnetism, are governed by those intricate quantum relations between particles. Understanding and modeling these complex properties are often based on a systematic restriction of the underlying parameter space to its relevant part. Here, we explore this concept using a quantum computing device rather than a classical computer.

Talking to friends in a crowded venue is sometimes difficult: the information one tries to get across gets washed out in the noisy environment. In this respect, quantum systems are no different. When they interact with the environment, they are subject to dephasing which ultimately destroys the information they hold.

Quantum simulations are expected to vastly outperform classical simulations when modeling the dynamics of interacting spin systems. Researchers have used a digital quantum simulation to show that spin dynamics can be studied and predicted, which lays the groundwork for applications in quantum magnetism and strongly correlated systems.

M. Pechal et al., Phys. Rev. X 4, 041010, published 17 October 2014

A coherent link between spatially separated nodes of a quantum network may be realized using itinerant photons as information carriers [1]. The necessary efficient absorption at the receiving node can be achieved by using a photon with a suitable temporal profile allowing time-reversal of the emission process [2].
