• Quantum computers, probably fake? Sounds fake and gay.

In quantum computing, quantum supremacy or quantum advantage is the goal of demonstrating that a programmable quantum computer can solve a problem that no classical computer can solve in any feasible amount of time, irrespective of the usefulness of the problem.[1][2][3] The term was coined by John Preskill in 2012,[1][4] but the concept dates back to Yuri Manin's 1980[5] and Richard Feynman's 1981[6] proposals of quantum computing.

In October 2021, teams from USTC again reported quantum primacy by building two supercomputers called Jiuzhang 2.0 and Zuchongzhi. The light-based Jiuzhang 2.0 implemented gaussian boson sampling to detect 113 photons from a 144-mode optical interferometer and a sampling rate speed up of 1024 – a difference of 37 photons and 10 orders of magnitude over the previous Jiuzhang.[52][53] Zuchongzhi is a programmable superconducting quantum computer that needs to be kept at extremely low temperatures to work efficiently and uses random circuit sampling to obtain 56 qubits from a tunable coupling architecture of 66 transmons — an improvement over Google's Sycamore 2019 achievement by 3 qubits, meaning a greater computational cost of classical simulation of 2 to 3 orders of magnitude.[54][55][56] A third study reported that Zuchongzhi 2.1 completed a sampling task that "is about 6 orders of magnitude more difficult than that of Sycamore" "in the classic simulation".[57]

In June 2022 Xanadu has reported on a boson sampling experiment summing up to those of Google and USTC, their setup used loops of optical fiber and multiplexing to replace the network of beam splitters by a single one which made it also more easily reconfigurable. They detected a mean of 125 up to 219 photon from 216 squeezed modes (squeezed light follows a photon number distribution so they can contain more than one photon per mode) and claim to have obtained a speedup 50 million times bigger than previous experiments.[58][59]

Inside, it's minus 460 degrees Fahrenheit (minus 273 degrees Celsius) in some spots, pockets of cold that bristle with the impossible physics of quantum mechanics, a science in which things can simultaneously exist, not exist and also be something in between.

a Google quantum computer’s processor could perform a calculation in just over 3 minutes which would take 10,000 years on IBM’s Summit supercomputer.
