Researchers at Toshiba Corporation (TOKYO: 6502) have achieved a breakthrough in quantum computer architecture: the basic design for a double-transmon coupler that will improve the speed and accuracy of quantum computation in tunable couplers. The coupler is a key device in determining the performance of superconducting quantum computers.

Tunable couplers in a superconducting quantum computer link two qubits and perform quantum computations by turning on and off the coupling between them. Current technology can turn off the coupling of transmon qubits with close frequencies, but this is prone to crosstalk errors that occur on one of the qubits when the other qubit is irradiated with electromagnetic waves for control. In addition, current technology cannot completely turn off coupling for qubits with significantly different frequencies, resulting in errors due to residual coupling.
Toshiba has recently devised a double-transmon coupler that can completely turn on and off the coupling between qubits with significantly different frequencies. Completely turning on enables high-speed quantum computations with strong coupling, while completely turning off eliminates residual coupling, which improves quantum computation speeds and accuracy. Simulations with the new technology have shown it realizes two-qubit gates, basic operations in quantum computation, with an accuracy of 99.99% and a processing time of only 24 ns.
Toshiba’s double-transmon coupler can be applied to fixed-frequency transmon qubits, realizing high stability and ease of design. It is the first to realize coupling between fixed-frequency transmon qubits with significantly different frequencies that can be completely switched on and off, and to deliver a high-speed, accurate two-qubit gate.
The technology is expected to advance the realization of higher-performance quantum computers that will contribute in such areas as the achievement of carbon neutrality and the development of new drugs. Details of the technology were published in the United States on September 15 in the Physical Review Applied, a journal of the American Physical Society (https://doi.org/10.1103/PhysRevApplied.18.034038).

U.S. FDA Approves Takeda’s ORZEYFUL™ (oveporexton), the First and Only Medicine to Treat the Underlying Cause of Narcolepsy Type 16.8.2026 00:10:00 CEST | Press release
Adults Taking ORZEYFUL Experienced Significant and Meaningful Improvements Across the Full Range of Symptoms of Narcolepsy Type 1 (NT1) in Clinical Trials Compared to Those on Placebo As a First-in-Class Orexin Treatment, ORZEYFUL has the Potential to Redefine NT1 Care Beyond Individual Symptoms Takeda is Advancing U.S. Launch Preparations and Expects to Make ORZEYFUL Available Following Completion of the Drug Enforcement Administration (DEA) Scheduling Process Takeda (TSE:4502/NYSE:TAK) announced that the U.S. Food and Drug Administration (FDA) approved ORZEYFUL™ (oveporexton), an oral orexin receptor 2 (OX2R) agonist, for the treatment of narcolepsy type 1 (NT1, narcolepsy with cataplexy) in adults.* The persistent 24-hour nature of NT1 is driven by orexin deficiency and can severely impact people’s lives. As a first-in-class orexin treatment, ORZEYFUL is the only medicine indicated in the U.S. to treat the disease holistically rather than individual symptoms. “The FDA approval of OR
