Online shopping boomed during the pandemic, but it remains vulnerable to scams involving both buyers and sellers. Quantum communication could, in principle, add another layer of security, but verifying a transaction securely, rather than simply communicating it, requires a “signature” consisting of thousands of quantum bits (qubits) for a single bit of message.

Physics World: Baidu and Alibaba plan to quit quantum computing research
The Chinese search engine company Baidu is giving up its quantum computing division by donating its entire research facility to the government-run Beijing Academy of Quantum Information Sciences (BAQIS). The company says that the two parties are currently in discussion over the details of the donation.
Nederlands Tijdschrift voor Natuurkunde: Pionierend experiment houdt spingolven onder controle
Een baanbrekend experiment bij de TU Delft laat voor het eerst zien dat magnetische golven, spingolven genaamd, door middel van supergeleiders beheersbaar zijn. Spingolven hebben de potentie om elektrische apparatuur efficiënter te maken of om als connectoren in een quantumcomputer te dienen. Het resultaat zet daarmee een flinke stap richting toepassingen van dit natuurkundige fenomeen.
Physics World: Entangled molecules make a novel qubit platform
Ultracold molecules are a step closer to being a viable platform for quantum technology thanks to two independent teams of researchers who showed they could entangle pairs of molecules and encode them as quantum bits (qubits). Because molecules offer new ways to encode quantum information and can interact with each other over long distances, the two works offer new possibilities in quantum computing and quantum simulations beyond those provided by other types of qubits.
