A passive copy of encrypted traffic taken from a cable, radio link, or satellite beam leaves nothing on the victim's network. Tools marketed against harvest-now, decrypt-later attacks watch for exfiltration, anomalous traffic, or quantum-vulnerable encryption instead.
Claudia Buch, who chairs the ECB's Supervisory Board, told bank chief executives that adopting post-quantum cryptography "must start now." She attached no deadline and said the ECB would address quantum risk in a separate letter.
Researchers reported in Nature Communications that eight physical qubits in a linear array kept their coherence. They demonstrated a two-qubit gate on one of four qubit pairs and reported no gate fidelities for the array.
Coordinated by LuxQuanta, the six-member QUARTERNEXT consortium plans 48 months of work on continuous-variable QKD equipment and intends to provide its hardware and software for testing at Nostradamus, the EU's QKD evaluation effort.
The Quantum Flagship had announced the academy's launch in May. The academy aims to train at least 600 people in master's- and doctoral-level programs by the project's end and to deliver training to 5,000 learners.
An ANSSI official told a Paris conference that the agency would stop certifying products without quantum-resistant encryption from 2027, Reuters reported. In its written guidance, ANSSI ties that year to qualification and advises against non-PQC purchases after 2030.
In measurement-device-independent QKD, an untrusted relay makes every measurement, so the detector attacks demonstrated on commercial systems no longer work. Researchers have still taken full keys through a flawed transmitter. Users also give up key rate.
Silicon spin qubits now come from 300 mm lines at imec, Intel, and STMicroelectronics. No maker has yet shown a fab supplying enriched silicon, qubits uniform enough to tune automatically at scale, or control electronics within a million-qubit power budget.
McKinsey took its $15.3 billion for China's public quantum funding from CIFAR, which converted a reported ¥100 billion for one national laboratory in 2021. No published Chinese budget confirms it. A congressman has described it as investment.
