Superconducting Qubits Are Getting Serious

Viewpoint Superconducting Qubits Are Getting Serious

Bigger is better. Rather interestingly, this mantra appears true for superconducting quantum bits (qubits), which are considered one of the most attractive physical realizations of quantum logic elements for quantum information processing. Reporting in Physical Review Letters, Hanhee Paik, at Yale University, and colleagues demonstrate a novel implementation of a superconducting qubit with dime...

Superconducting phase qubits

Experimental progress is reviewed for superconducting phase qubit research at the University of California, Santa Barbara. The phase qubit has a potential advantage of scalability, based on the low impedance of the device and the ability to microfabricate complex “quantum integrated circuits”. Single and coupled qubit experiments, including qubits coupled to resonators, are reviewed along with ...

Superconducting Qubits Ii : Decoherence

This is an introduction to elementary decoherence theory as it is typically applied to superconducting qubits. Abbreviations: SQUID – superconducting quantum interference device; qubit – quantum bit; TSS – two state system
