Qubit Physics

Here, we briefly discuss QPU (Quantum Processing Unit) design. Current quantum circuits are two-dimensional, with inter-qubit interactions typically limited to neighboring qubits. Coupled with common error correction designs (QEC), such as the surface code, which adopts a square design, each QPU qubit only needs four couplers for neighboring qubits. IQM has also proposed new QPU designs incorporating computational resonators to enable more advanced quantum computing methods. We may write more about this in the future.
