Beyond-classical computation in quantum simulation
Andrew D. King, Alberto Nocera, Marek M. Rams +60
Quantum computers hold the promise of solving certain problems that lie beyond the reach of conventional computers. However, establishing this capability, especially for impactful…
Probing flux and charge noise with macroscopic resonant tunneling
Alexander M. Whiticar, Anatoly Y. Smirnov, Trevor Lanting +8
We report on measurements of flux and charge noise in an rf-SQUID flux qubit using macroscopic resonant tunneling (MRT). We measure rates of incoherent tunneling from the lowest en…
Quantum critical dynamics in a 5000-qubit programmable spin glass
Andrew D. King, Jack Raymond, Trevor Lanting +24
Experiments on disordered alloys suggest that spin glasses can be brought into low-energy states faster by annealing quantum fluctuations than by conventional thermal annealing. Du…
Spectroscopic Characterization of the Quantum Linear-Zigzag Transition in Trapped Ions
J. Zhang, B. T. Chow, S. Ejtemaee +1
While engineered quantum systems are a general route to the manipulation of multipartite quantum states, access in a physical system to a continuous quantum phase transition under…
Coherent quantum annealing in a programmable 2000-qubit Ising chain
Andrew D. King, Sei Suzuki, Jack Raymond +21
Quantum simulation has emerged as a valuable arena for demonstrating and understanding the capabilities of near-term quantum computers. Quantum annealing has been used successfully…
Architectural considerations in the design of a third-generation superconducting quantum annealing processor
Kelly Boothby, Colin Enderud, Trevor Lanting +46
Early generations of superconducting quantum annealing processors have provided a valuable platform for studying the performance of a scalable quantum computing technology. These s…
Scaling advantage in quantum simulation of geometrically frustrated magnets
Andrew D. King, Jack Raymond, Trevor Lanting +51
The promise of quantum computing lies in harnessing programmable quantum devices for practical applications such as efficient simulation of quantum materials and condensed matter s…
3D Sisyphus Cooling of Trapped Ions
S. Ejtemaee, P. C. Haljan
Using a laser polarization gradient, we realize 3D Sisyphus cooling of Yb ions confined in and near the Lamb-Dicke regime in a linear Paul trap. The cooling rate and fi…
Spontaneous nucleation and dynamics of kink defects in zigzag arrays of trapped ions
S. Ejtemaee, P. C. Haljan
The spontaneous nucleation and dynamics of topological kink defects have been studied in trapped arrays of 41-43 Yb ions. The number of kinks formed as a function of quench rate ac…
