Researchers studying the heavy-fermion superconductor UTe2 examined whether a newly observed memory effect—where past current pulses alter later superconducting behavior—could simply be an artifact of Joule heating from the applied current pulses. By analyzing temperature during pulse protocols and testing how the effect scales with current amplitude, duration, and especially the speed at which current is switched off, they found the memory effect strengthens with faster relaxation rates, which actually reduces total energy deposited, undermining a simple heating explanation.

According to a Diamond Online report, NEC quietly halted development of physical quantum computing machines at the end of March 2026, decades after pioneering superconducting qubit research in 1999. Several researchers from the program, including a key leader, have reportedly since joined Fujitsu, which continues investing heavily in the technology. NEC has not confirmed a full exit, stating it still evaluates practical applications and industrialization of quantum technologies with customers.

EuroHPC Joint Undertaking has launched six funding calls totaling €119 million to develop next-generation quantum computing infrastructure across Europe, including trapped-ion and superconducting platforms. The trapped-ion call, worth €20 million, targets a full-stack quantum computer with over 1,000 qubits integrated with HPC systems, while the superconducting call seeks a similarly scaled chiplet-based QPU with cloud access. Both calls opened August 13, 2026, with applications due November 17, 2026.
