Quantum 5, 515 (2021). https://doi.org/10.22331/q-2021-08-03-515 We study the relation of causal influence between input systems of a reversible evolution and its output systems, in the context of operational probabilistic theories. We analyse two different definitions […]
Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information storage unit […]
Two physicists, from EPFL and Columbia University, have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses […]
Quantum 5, 514 (2021). https://doi.org/10.22331/q-2021-08-03-514 Given a closed quantum system, the states that can be reached with a cyclic process are those with the same spectrum as the initial state. Here we prove that, under […]
The National University of Singapore (NUS) will collaborate with Amazon Web Services (AWS) to research quantum communication and quantum computing technologies and also to explore potential industry applications of quantum capabilities. The collaboration will be […]
For years, I’ve had a private term I’ve used with my family. To give a few examples of its use: No, I never applied for that grant. I spent two hours struggling to log in […]

Time crystals sound suspiciously like a component of a time machine, but they’re not, at least not right now. Time crystals are actually a novel phase of matter — mostly theoretical — composed of parts […]
As the midday sun hangs over the Scandinavian spruce forest, a swarm of hopeful suitors takes to the air. They are dance flies, and it is time to attract a mate. Zigzagging and twirling, the […]
