Summary
Quantum computers promise capabilities far beyond those of today’s classical machines, with potential applications in areas such as materials discovery, secure communication, and advanced sensing. However, existing quantum processors face major engineering barriers to continued progress. Present day superconducting quantum processors are built as single, monolithic chips in which all quantum bits (qubits) reside on a single substrate. As systems grow, this architecture becomes increasingly fragile: crosstalk rises, wiring becomes unmanageable, and a single faulty component can compromise the e
