Superconducting circuits have played an essential role in realizing quantum mechanical phenomena in macroscopic systems. One such example is the observation of macroscopic resonant tunneling (MRT) of magnetic flux between the lowest energy states of single rf-SQUID flux qubits, as demonstrated by several groups [1–4]. These measurements provide both a clear signature of quantum mechanics in a macroscopic circuit at a finite temperature and in the presence of noise and a direct means of…

1 / f noise: Implications for solid-state quantum information
The efficiency of the future devices for quantum information processing will be limited mostly by the finite decoherence rates of the individual qubits and quantum gates. Recently, substantial
Thermally assisted quantum annealing of a 16-qubit problem.
TLDR
It is experimentally demonstrated that, even with annealing times eight orders of magnitude longer than the predicted single-qubit decoherence time, the probabilities of performing a successful computation are similar to those expected for a fully coherent system.

TLDR
It is shown that 8-qubit tunnelling plays a computational role in a currently available programmable quantum annealer, and a nonperturbative theory of open quantum dynamics under realistic noise characteristics is developed that accurately predicts the rate of many-body dissipative quantum Tunnelling subject to the polaron effect.

Finite temperature quantum annealing solving exponentially small gap problem with non-monotonic success probability
TLDR
The authors show a nonmonotonic behavior of a quantum annealing processor, explaining it in terms of thermally accessible states, consistent with a quantum open-system description that is unrelated to thermal relaxation, and is instead dominated by the system's properties at the critical point.
Simulating chemistry using quantum computers.

This review discusses to what extent the ideas in quantum computation, now a well-established field, have been applied to chemical problems and describes algorithms that achieve significant advantages for the electronic-structure problem, the simulation of chemical dynamics, protein folding, and other tasks.

TLDR
Macroscopic resonant tunneling between the two lowest lying states of a bistable rf SQUID is used to characterize noise in a flux qubit and indicates that the dominant source of low energy flux noise is a quantum mechanical environment in thermal equilibrium.
