Make: Japan | 「Maker Faire Tokyo 2020」レポート #5 — 量子ビットの操作を可視化した「8bit Quantum Computer」
2020.11.10 「Maker Faire Tokyo 2020」レポート #5 — 量子ビットの操作を可視化した「8bit Quantum Computer」 Text by Takako Ouchi 鉄板の上に砂をかけ、スイッチを入れると独特の絵が浮かびあがる。時間が立つとともに、描かれる絵は移り変わっていく。そんな不思議な装置を作って、Maker Faire Tokyo 2020にやってきたのは、新里祐教さんと今村謙之さん。 これは量子コンピューターのQPU（ノイマン型コンピューターのCPUにあたる）における量子ビット（Qubit）の操作を表現したものだ。量子コンピューターは、量子の状態を使ってビットを表現する。その量子の状態の変化を「砂で描いたクラドニ図が音波により変わる」ことで表している。 もともと未踏に採択されたプロジェクトがあり、そこから生まれた作品である。未踏のプロジェ
Breaking RSA with a Quantum Computer - Schneier on Security
Breaking RSA with a Quantum Computer A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong. We have long known from Shor’s algorithm that factoring with a quantum computer is easy. But it takes a big quantum computer, on the o
Since 1987 - Covering the Fastest Computers in the World and the People Who Run Them Since 1987 - Covering the Fastest Computers in the World and the People Who Run Them What is one to make of the quantum computing market? Energized (lots of funding) but still chaotic and advancing in unpredictable ways (e.g. competing qubit technologies), the quantum computing landscape is transforming at a blurr
D-Wave Announces General Availability of First Quantum Computer Built for Business
BURNABY, BC – September 29, 2020 — D-Wave Systems Inc., the leader in quantum computing systems, software, and services, today announced the general availability of its next-generation quantum computing platform, incorporating new hardware, software, and tools to enable and accelerate the delivery of in-production quantum computing applications. Available today in the Leap™ quantum cloud service,
D-Wave plans to build a gate-model quantum computer | TechCrunch
For more than 20 years, D-Wave has been synonymous with quantum annealing. Its early bet on this technology allowed it to become the world’s first company to sell quantum computers, but that also somewhat limited the real-world problems its hardware could solve, given that quantum annealing works especially well for optimization problems like protein folding or route planning. But as the company a

How to Turn a Quantum Computer Into the Ultimate Randomness Generator | Quanta Magazine
Say the words “quantum supremacy” at a gathering of computer scientists, and eyes will likely roll. The phrase refers to the idea that quantum computers will soon cross a threshold where they’ll perform with relative ease tasks that are extremely hard for classical computers. Until recently, these tasks were thought to have little real-world use, hence the eye rolls. But now that Google’s quantum
Chinese researchers claim to have broken RSA with a quantum computer. Experts aren’t so sure.
Chinese researchers claim to have broken RSA with a quantum computer. Experts aren’t so sure. Researchers in China claim to have reached a breakthrough in quantum computing, figuring out how they can break the RSA public-key encryption system using a quantum computer of around the power that will soon be publicly available. Breaking 2048-bit RSA — in other words finding a method to consistently an
