技術の現状
Recent breakthroughs have substantially reduced error rates. A new qubit design achieves 100 times lower error proneness in superfluid quantum computers, while scientists have solved a 25 year entanglement challenge in quantum teleportation. These advances move quantum systems from theoretical to practical territory.
市場と地政学的競争
The United States and China dominate quantum development, with tracked signals indicating intense activity in both nations. Stock market attention has grown significantly, with major announcements from companies like IonQ capturing investor interest. This competition will likely accelerate deployment timelines, though scaling to useful quantum advantage across industries will take several more years.
