In the last few years, you predicted a revolution, societally, once we hit the
heights in successfully entangled, quantum operations. Have you changed your
mind since this prediction?

Apparently IBM has hardwired a new error correcting algorithm into its new
quantum chip called "Quantum Low-Density Parity Check" (qLDPC), only 288
physical Qubits are needed (provided the physical error rate is less than 0.1%)
to produce 12 perfect logical cubits; with older error correction codes many
thousands of physical Qubits would have been required. The difficult part was
that for qLDPC to work each physical Qubit had to be connected to 6 other
Qubits, in older quantum chips there was only a connection with two or three.
