Quantum computing: cold chips can control qubits

© 2021 EPFL A cryogenic controller chip opens the door to solving the ‘wiring bottleneck’ and subsequently to realize a fully integrated, scalable quantum computer. A research from QuTech in the Netherlands, from Intel Corp and from EPFL. A specially designed chip to control qubits can operate at extremely low temperatures, and opens the door to solving the ‘wiring bottleneck’. Researchers and engineers from QuTech in the Netherlands and from Intel Corp., jointly designed and tested the cryogenic chip and made an important step towards a scalable quantum computer. Their results are published in the scientific journal Nature. Each basic unit of a quantum computer, a qubit, is typically addressed individually by a single wire. ‘This stands in the way of a scalable quantum computer, since millions of qubits would require millions of wires’ explains lead investigator Lieven Vandersypen from QuTech. ‘This is called the ‘wiring bottleneck’.

Europe moves to exclude neighbors from its quantum and space research

Share A department overseen by European Union research commissioner Mariya Gabriel wants to safeguard strategic research by barring non-EU researchers. AP Photo/Francisco Seco Europe moves to exclude neighbors from its quantum and space research Mar. 11, 2021 , 4:25 PM In a sign of growing national tensions over the control of strategic research, the European Commission is trying to block countries outside the European Union from participating in quantum computing and space projects under Horizon Europe, its new research funding program. The proposed calls, which must still be approved by delegates from the 27 EU member states in the coming weeks, would shut out researchers in countries accustomed to full access to European research programs, including Switzerland, the United Kingdom, and Israel. European Economic Area (EEA) countries Norway, Lichtenstein, and Iceland would be barred from space research calls while remaining eligible for quantum computing projects.

Microsoft quantum lab retracts published paper: Readings that cast doubt on crucial discovery went AWOL

Quasiparticle eggheads were caught up in the enthusiasm of the moment Katyanna Quach Tue 9 Mar 2021 // 08:55 UTC Share Copy Updated A paper published in Nature two years ago and spearheaded by a Microsoft scientist has been retracted after it emerged that the data presented simply didn t add up. The work was produced at a quantum computer lab set up by Microsoft and QuTech, a research center co-founded by the Delft University of Technology (TU Delft) in the Netherlands. The study, led by Microsoftie and TU Delft Professor Leo Kouwenhoven, reported the discovery of a theoretical quasiparticle the academics believed would prove useful for future quantum computers.
