Barcelona-based Qilimanjaro has launched EduQit, a kit containing all parts needed to assemble a small quantum computer. Priced at around €1 million with five qubits, it targets research institutions and students lacking resources. Assembly requires engineering skills and up to 10 months of work with provided training.

IonQ announced Q4 revenue of $61.9 million, a 429% increase year-over-year, accounting for nearly half of its 2025 total revenue. The company also saw remaining performance obligations rise to $370 million, up from $77 million the previous year. This performance highlights growing commercial demand for its quantum computing technology.

Researchers have reduced the quantum computing power required to break the widely used RSA encryption algorithm by a factor of ten, to about 100,000 qubits. This advancement builds on prior work and highlights growing vulnerabilities in current security systems. However, significant engineering challenges persist in building such machines.

The Ethereum Foundation has formed a dedicated Post-Quantum team to address emerging threats from quantum computing. Led by Thomas Coratger, the initiative focuses on upgrading the network's cryptographic foundations before potential risks materialize. This move reflects a broader shift in the blockchain ecosystem toward proactive defenses.
