Quantum 6, 701 (2022). https://doi.org/10.22331/q-2022-04-27-701 The average entanglement entropy (EE) of the energy eigenstates in non-vanishing partitions has been recently proposed as a diagnostic of integrability in quantum many-body systems. For it to be a […]
Quantum 6, 700 (2022). https://doi.org/10.22331/q-2022-04-27-700 We carefully examine critical metrology and present an improved critical quantum metrology protocol which relies on quenching a system exhibiting a superradiant quantum phase transition beyond its critical point. We […]
Quantum computing holds the potential to be a game-changing future technology in fields ranging from chemistry to cryptography to finance to pharmaceuticals. Compared to conventional computers, scientists suggest that quantum computers could operate many thousand […]
When scientists think about the movement of microbes between animal species, we generally focus on “spillover” events: when pathogens move from animals to humans. But pathogen transmission isn’t a one-way street. Humans appear to have […]
Quantum 6, 699 (2022). https://doi.org/10.22331/q-2022-04-27-699 Observed quantum correlations are known to determine in certain cases the underlying quantum state and measurements. This phenomenon is known as $textit{(quantum) self-testing}$. Self-testing constitutes a significant research area with […]
Quantum 6, 698 (2022). https://doi.org/10.22331/q-2022-04-27-698 We consider a topological stabilizer code on a honeycomb grid, the “XYZ$^2$” code. The code is inspired by the Kitaev honeycomb model and is a simple realization of a “matching […]
Quantum 6, 697 (2022). https://doi.org/10.22331/q-2022-04-27-697 Photon losses are intrinsic for any translationally invariant optical imaging system with a non-trivial Point Spread Function, and the relation between the transmission factor and the coherence properties of an […]
Quantum 6, 696 (2022). https://doi.org/10.22331/q-2022-04-27-696 We describe an optimal procedure, as well as its efficient software implementation, for exact and approximate synthesis of two-qubit unitary operations into any prescribed discrete family of XX-type interactions and […]
Lausanne, Switzerland and Corbeil-Essones, France – April 27, 2022 LIGENTEC SA, the leading supplier of high performance, low loss, silicon nitride Photonic Integrated Circuits established a R&D Centre in France. Photonic integrated circuits (PICs) are […]
Researchers say they’ve found a way to significantly increase the probability of observing the Unruh effect, a ‘quantum glow’ phenomenon that was first proposed in the 1970s. Click to rate this post! [Total: 0 Average: […]
