26 September – 2 October 2026

Break-even, dequantization and the control stack

A claimed chemistry break-even on 120 qubits, a new classical-sampling limit for noisy unital circuits, and spin-qubit initialization without local reservoirs. With selected research from IBM, QuEra and RIKEN.

19–25 September 2026

Advantage, codes and the burden of proof

A quantum advantage claim run through a standard cloud queue, a fast-moving front in new error-correcting codes, and error correction moving into the hardware stack. With selected research from BlueQubit on IBM hardware, MIT and a photonic processor in orbit.

12–18 September 2026

Manufacturing, memory and the work of deployment

Wafer-scale statistics, a 90% optical memory and quantum signals sharing fiber with 10 Gbps traffic: this week’s research made deployment constraints measurable. With selected research from the University of Illinois, LuxQuanta and IBM.

5–11 September 2026

Control, algorithms and the work of scaling

The systems around the qubit come into focus: control, the cost of quantum algorithms, and the connections needed to scale. With selected research from IBM, NTT, and JPMorgan Chase.
