Scientists pushing the limits of the world’s most advanced neutron scattering instruments know that a small amount of distortion in their measurements is inevitable. For some experiments, this distortion is easily accounted for, but in […]
They are everywhere, around us and within us. Phenomena lasting trillionths of a second form the core of chemistry and biology. It is only recently that we have begun to try to accurately record their actual course, with […]
As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically reply […]
Quantum 6, 709 (2022). https://doi.org/10.22331/q-2022-05-09-709 We introduce a new open-source software library $Jet$, which uses task-based parallelism to obtain speed-ups in classical tensor-network simulations of quantum circuits. These speed-ups result from i) the increased parallelism […]
A major hurdle for work at the forefront of fundamental physics is the inability to test cutting-edge theories in a laboratory setting. But a recent discovery opens the door for scientists to see ideas in […]
As the Internet of Things expands, engineers want to embed AI into everything, but the amount of energy it requires is a challenge for the smallest and most remote devices. A new “nanomagnetic” computing approach […]
For scientists studying de-extinction — the ambitious effort to resurrect extinct species — a paper that appeared in Current Biology in March was a sobering reality check. Thomas Gilbert, a genomics researcher and professor at […]
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed […]
Quantum 6, 708 (2022). https://doi.org/10.22331/q-2022-05-09-708 We introduce finite-function-encoding (FFE) states which encode arbitrary $d$-valued logic functions, i.e., multivariate functions over the ring of integers modulo $d$, and investigate some of their structural properties. We also […]
Quantum 6, 707 (2022). https://doi.org/10.22331/q-2022-05-09-707 The quantum volume test is a full-system benchmark for quantum computers that is sensitive to qubit number, fidelity, connectivity, and other quantities believed to be important in building useful devices. […]
