As an RF/Microwave engineer, I think the elephant in the room are the control electronics. Presently these are racks of equipment for a few logical qubits.
Isn’t there a spareness limit to the qubit arrays to maintain entanglement? How are the read and write electronics going to be reasonably sized, or ever going to achieve the density needed for a million physical qubits?
- tengwar2 4y agoAre there any problems for which that number of qubits is needed? The problems in physical chemistry that I have seen seem to require up to about 250 qubits, and cryptography seems somewhat more economical.
- AlanYx 4y agoAny practical problem requiring only 250 qubits is in reference to error-corrected logical qubits. You need about 10,000 qubits to create one error-corrected logical qubit.
