Chalmers University Demonstrates Hardware-Level Microwave Crosstalk Suppression via Parasitic Capacitance Engineering

Physicists at Chalmers University of Technology have developed a new method to eliminate microwave crosstalk in superconducting processors. Their research shows that by engineering on-chip parasitic capacitances, they can achieve destructive interference among parasitic capacitive channels, suppressing unwanted qubit excitations. This method offers a practical advantage for floating transmons and allows for alignment of classical microwave crosstalk nulls with quantum ZZ nulls. The post Chalmers
