It has long been known that graphene has excellent electronic properties. However, it was unclear until now how stable these properties are. Are they destroyed by disturbances and additional effects, which are unavoidable in practice, […]
Does hot water freeze faster than cold water? Aristotle may have been the first to tackle this question that later became known as the Mpemba effect. Click to rate this post! [Total: 0 Average: 0]You […]
The United Kingdom’s second quantum hackathon, held on 25th — 26th July, presented a challenge to ten squads of early-career researchers, mentors from the industry, and experts in hardware. Their task: conceive quantum solutions to real-world issues […]
Quantum 7, 1098 (2023). https://doi.org/10.22331/q-2023-08-29-1098 In standard quantum mechanics, reference frames are treated as abstract entities. We can think of them as idealized, infinite-mass subsystems which decouple from the rest of the system. In nature, […]
Quantum 7, 1097 (2023). https://doi.org/10.22331/q-2023-08-29-1097 Linear optical quantum circuits with photon number resolving (PNR) detectors are used for both Gaussian Boson Sampling (GBS) and for the preparation of non-Gaussian states such as Gottesman-Kitaev-Preskill (GKP), cat […]
Quantum 7, 1096 (2023). https://doi.org/10.22331/q-2023-08-29-1096 Neural network approaches to approximate the ground state of quantum hamiltonians require the numerical solution of a highly nonlinear optimization problem. We introduce a statistical learning approach that makes the […]
Quantum 7, 1095 (2023). https://doi.org/10.22331/q-2023-08-29-1095 Recent studies showed the finite-size security of binary-modulation CV-QKD protocols against general attacks. However, they gave poor key-rate scaling against transmission distance. Here, we extend the security proof based on […]
Last October, as the James Webb Space Telescope beamed down its first long exposures of the sky near the constellation Eridanus, astronomers began to piece together the story of a dim, flickering point of light […]
Insider Brief QuEra Computing announced an increase in the availability of the device from 10 to 48 hours per week on Amazon Braket. This expansion in capacity makes it even more convenient for customers around the […]
The field of quantum physics is rife with paths leading to tantalizing new areas of study, but one rabbit hole offers a unique vantage point into a world where particles behave differently—through the proverbial looking […]
