		<description><![CDATA[https://etn.fi/index.php/13-news/18900-qmill-lupaa-kvanttiedun-paljon-odotettua-aiemmin

Kvanttilaskennan algoritmeja kehittävä suomalaisyhtiö QMill väittää voivansa nopeuttaa kvanttiedun saavuttamista jopa vuosilla. – Ala on pitkään ajatellut, että tarvitaan satoja tai tuhansia kubitteja ennen kuin kvanttikoneista saadaan käytännön hyötyä. Nyt näyttää siltä, että tietyissä ongelmissa kvanttietu voidaan saavuttaa paljon pienemmillä koneilla, sanoo QMillin tuotevastaava Janne Heikkinen ETN:lle.

QMillin mukaan ratkaisevaa ei enää ole pelkkä kubittien määrä, vaan se, kuinka tehokkaasti kvanttialgoritmit ja kvanttipiirit voidaan optimoida nykyisille, edelleen virhealttiille kvanttikoneille.

Heikkisen mukaan kvanttietu ei synny enää vain kvanttirautaa kasvattamalla. Yhä tärkeämmäksi nousee kvanttikoneen tarkkuus eli fideliteetti. Nykyiset NISQ-kvanttikoneet ovat edelleen herkkiä kohinalle ja virheille, jotka kasvavat nopeasti kvanttioperaatioiden määrän kasvaessa. NISQ eli Noisy Intermediate-Scale Quantum tarkoittaa nykyisiä kvanttitietokoneita, joissa on jo kymmeniä tai satoja kubitteja, mutta jotka ovat edelleen herkkiä kohinalle ja laskentavirheille.

– Kubitit määrittävät kvanttipiirin leveyden, mutta portit määrittävät pituuden. Kun portteja tulee liikaa, virheet kumuloituvat ja laskennan laatu romahtaa, Heikkinen kuvaa.]]></description>

Chinese state media: CAS Cold Atom Technology has built the 200-qubit Hanyuan-2, the world&#039;s first dual-core quantum computer, with a core for error correction

China&#039;s Hanyuan-2 debuts as &#039;world&#039;s first&#039; dual-core quantum computer — 200-qubit claims incredible power efficiency, but lacks critical performance benchmarks

Metrics and peer-reviewed papers seem to be lacking.

CAS Cold Atom Technology, a Wuhan-based firm affiliated with the Chinese Academy of Sciences (CAS), unveiled what it claims is the world&#039;s first dual-core quantum computer, according to a report from state-owned publication Science and Technology Daily. The system, called Hanyuan-2, pairs two independent neutral atom arrays inside a single cabinet-sized machine, totaling 200 qubits built from 100 rubidium-85 and 100 rubidium-87 atoms.

The company said the twin cores can either run in parallel to split workloads or operate in a &quot;one main and one auxiliary&quot; configuration, where the second array handles real-time error correction while the first executes computations. Ge Guiguo, a senior expert at CAS Cold Atom Technology, told Science and Technology Daily that the system represents the first time a quantum processor has moved from single-core to dual-core architecture.

Hanyuan-2 is built on neutral atom technology, which traps uncharged atoms using laser arrays to cool and manipulate individual neutral atoms as qubits. CAS Cold Atom Technology&#039;s general manager, Tang Biao, said the machine uses a compact, cabinet-style integrated design with a small laser cooling system, with total power consumption sitting below 7 kilowatts.]]></description>
