A team of Chinese physicists has achieved a landmark advance in quantum communication, successfully teleporting quantum states between two ground stations 1,200 kilometers apart via Micius satellite​. The experiment, led by Pan Jianwei of the University of Science and Technology of China, marks the longest-distance quantum ...

26 Jan 2022 - For a decade, silicon spin qubits have been quantum computing's most tantalizing "not yet." The pitch was always compelling: qubits built from the same material that powers every smartphone and data centre on earth, manufactured using processes the semiconductor industry has ...

Zurich-based startup Terra Quantum raised a hefty $60 million in Series A financing to build out its “quantum-as-a-service” platform. Announced in January 2022, this was one of Europe’s largest quantum tech funding rounds at the time. Terra Quantum offers a hybrid quantum computing platform - combining classical ...

IBM has announced Eagle, a 127-qubit superconducting quantum processor – the world’s first quantum chip to surpass 100 qubits​. Unveiled at the IBM Quantum Summit in late 2021, Eagle marks a major milestone in quantum computing, nearly doubling the qubit count of IBM’s previous 65-qubit ...

A new preprint by Elie Gouzien and Nicolas Sangouard proposes an architectural trade: replace the “millions of qubits in one giant chip” model with a small quantum processor plus a very large multimode quantum memory. Under optimistic - but clearly stated - fault-tolerance assumptions, the authors estimate that factoring an RSA-2048 ...

Dutch quantum hardware startup QuantWare has announced the launch of commercially available superconducting quantum processing units (QPUs), aiming to make superconducting qubit hardware accessible “off the shelf” and on short lead times. The company says easier access to superconducting processors - an approach used in ...

A major corporate development in July 2021 saw German tech group Rohde & Schwarz acquire Zurich Instruments, a Swiss test & measurement firm known for its quantum control electronics. Zurich Instruments, a spin-off from ETH Zurich, had become a leader in specialized instrumentation for quantum ...

A team of Chinese physicists has unveiled Zuchongzhi 2.0, a cutting-edge 66-qubit superconducting quantum computing prototype that pushes the frontiers of computational power. Announced by the CAS Center for Excellence in Quantum Information, this new quantum machine builds on its predecessor (Zuchongzhi 1.0) with more ...

In May 2021, scientists at the Chinese Academy of Sciences (CAS) unveiled Zuchongzhi 1.0, a 62-qubit programmable superconducting quantum computer that set a new benchmark in the quantum computing race. Named after a 5th-century Chinese mathematician, Zuchongzhi 1.0 contains the largest number of superconducting qubits ...

The European Union Agency for Cybersecurity (ENISA) has recently published a report titled "Post-Quantum Cryptography: Current State and Quantum Mitigation." This study offers a detailed overview of the current progress in the standardization process of Post-Quantum Cryptography (PQC), crucial for safeguarding digital communications against the ...

May 2021 - ETH Zurich and the Paul Scherrer Institute (PSI) opened a new joint Quantum Computing Hub dedicated to developing next-generation quantum computers. Backed by CHF 32 million from ETH, the center in canton Aargau brings together about 30 researchers under one roof. Uniquely, ...

An interesting paper was published on arXiv, the preprint server. Titled "How to factor 2048 bit RSA integers in 8 hours using 20 million noisy qubits," the paper by Craig Gidney and Martin Ekerå combines previous techniques from Shor (1994), Griffiths-Niu (1996), Zalka (2006), Fowler ...

A team of Chinese scientists has announced a breakthrough in quantum computing with the development of Jiuzhang, a photonic quantum processor that achieved a major computational milestone. In experiments reported on December 3, 2020, Jiuzhang completed in 200 seconds a mathematical problem that researchers estimate ...

Vancouver-area company D-Wave Systems - the world’s first commercial quantum computing firm - launched its Advantage quantum annealer, boasting over 5,000 qubits and a radically expanded 15-way qubit connectivity. This machine marked a leap from its previous 2,000-qubit system and demonstrated that D-Wave’s unique quantum ...

The Swiss Science Council released a landmark white paper on quantum technologies, outlining a national strategy to capitalize on Switzerland’s strengths in quantum computing, communication, sensing, and cryptography. This roadmap calls for greater coordination and investment across government, academia, and industry to ensure the country ...

In late 2019, the International Telecommunication Union (ITU) quietly reached a milestone in cybersecurity: it approved a new standard that could redefine how we secure data in the coming quantum era. The standard, known as ITU-T Recommendation Y.3800, is an “Overview on networks supporting Quantum ...

Google announced that its 53-qubit quantum processor, Sycamore, has achieved a long-anticipated milestone known as “quantum supremacy.” In a paper published in Nature, the Google AI Quantum team reported that Sycamore performed a specific computation in approximately 200 seconds – a task they estimated would ...

On December 21, 2018, the United States solidified its commitment to quantum technology advancement by enacting the H.R.6227 - National Quantum Initiative Act. Passed with near-unanimous support from both houses of Congress, this landmark legislation outlines a comprehensive 10-year plan aimed at maintaining and enhancing ...
