Characterizing and optimizing qubit coherence based on SQUID geometry

Jochen Braumüller, Leon Ding, Antti Vepsäläinen +12

The dominant source of decoherence in contemporary frequency-tunable superconducting qubits is 1/ flux noise. To understand its origin and find ways to minimize its impact, we s…

Programming a quantum computer with quantum instructions

Morten Kjaergaard, Mollie E. Schwartz, Ami Greene +20

The equivalence between the instructions used to define programs and the input data on which the instructions operate is a basic principle of classical computer architectures and p…
