Quantum 7, 921 (2023). https://doi.org/10.22331/q-2023-02-09-921 As the width and depth of quantum circuits implemented by state-of-the-art quantum processors rapidly increase, circuit analysis and assessment via classical simulation are becoming unfeasible. It is crucial, therefore, to […]
Quantum 7, 920 (2023). https://doi.org/10.22331/q-2023-02-09-920 A quantum internet aims at harnessing networked quantum technologies, namely by distributing bipartite entanglement between distant nodes. However, multipartite entanglement between the nodes may empower the quantum internet for additional […]
Quantum 7, 919 (2023). https://doi.org/10.22331/q-2023-02-09-919 The topology of classical networks is determined by physical links between nodes, and after a network request the links are used to establish the desired connections. Quantum networks offer the […]
Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by […]
I have a confession: When I was 4, I was kicked out of ballet class for asking too many questions. I asked why a lot, like any kid. And I guess the teacher didn’t appreciate […]
Insider Brief Positioned in the quantum security segment, Terra Quantum delivers end-to-end solutions for data and information safety. Investcorp’s leadership in the cyber security sector paired up with its proven track-record in digital sectors and […]
Quantum 7, 918 (2023). https://doi.org/10.22331/q-2023-02-09-918 In a previous work [J. Chem. Phys. 155, 244111 (2021)], we found counterexamples to the fundamental Hohenberg-Kohn theorem from density-functional theory in finite-lattice systems represented by graphs. Here, we demonstrate […]
Quantum 7, 917 (2023). https://doi.org/10.22331/q-2023-02-09-917 The quantum kicked rotor is well-known for displaying dynamical (Anderson) localization. It has recently been shown that a periodically kicked Tonks gas will always localize and converge to a finite […]
Quantum 7, 916 (2023). https://doi.org/10.22331/q-2023-02-09-916 Computing the ground-state properties of quantum many-body systems is a promising application of near-term quantum hardware with a potential impact in many fields. The conventional algorithm quantum phase estimation uses […]
The European Space Agency’s Advanced Concepts Team (https://www.esa.int/gsp/ACT/) is looking for a highly motivated young researcher with an interest in theoretical quantum physics and quantum technology. The precise areas of research will be partly chosen […]
