Quantum control at QCE26 raced the error-correction stopwatch

This guide follows 55 talks on quantum control at IEEE Quantum Week 2026 in Toronto. Many of them raced one deadline, the few millionths of a second that error correction allows. On the evening of Sunday 13 September, Gilad Ben-Shach of Quantum Machines gave the week’s first keynote and started a stopwatch. It ran through every later talk on control and qubit calibration. A measurement must be decoded and a fix sent back to the qubits within about 10 microseconds, Ben-Shach said. A slower loop lets error correction fall behind. From then on, every maker of control boxes in Toronto was in effect racing that clock, from the big vendors to the national labs that give their designs away. A quantum processor cannot do anything on its own. It is a small chip in a ring of ordinary electronics, and those racks turn each gate into a shaped pulse of microwaves, laser light or voltage. The timing has to be right to within billionths of a second, across hundreds of channels at once, and the same racks must read the answers back. Qubits drift, too. The pulses that worked this morning may be wrong by the afternoon. Taken together, the…
