Smaller, higher performance/ fidelity superconducting modular quantum processors for building scalable quantum computers

"more attractive option for building system networks... system enabling manipulation of 2 qubits jointly so as to create entanglement or gate operations between them... only find out that something went wrong after putting it together, overcome with system that can be taken apart/ put it back together... 2 devices connected with superconducting coaxial cables to link qubits across modules exhibits ~99% SWAP gate fidelity, representing less than 1% loss... scalable, fault-tolerant and reconfigurable quantum computers"
