Tunable coupling of superconducting qubits has been widely studied due to its importance for isolated gate operations in scalable quantum processor architectures. Here, we demonstrate a tunable qubit-qubit coupler based on floating transmon device, which allows us place at least 2 mm apart from each other while maintaining over 50-MHz between the and qubits. In introduced tunable-coupler design, both qubit-coupler couplings are mediated by two waveguides instead relying direct capacitive...
We propose a new quantum transition-state theory for calculating Fermi's golden-rule rates in complex multidimensional systems. This method is able to account the nuclear effects of delocalization, zero-point energy, and tunneling an electron-transfer reaction. It related instanton but can be computed by path-integral sampling thus applicable treat molecular reactions solution. A constraint functional based on energy conservation introduced which ensures that dominant paths contributing...
The manageability and resilience of critical infrastructures, such as power water networks, is challenged by their increasing interdependence interconnectivity. Power networks often experience cascading failures, i.e. blackouts, that have unprecedented economic social impact. Al- though knowledge exists about how to control complex non-linear phenomena within a single network, little known failures can spread coevolve in the network when failing components energize distribution...
We explore the relation between quantum and semiclassical instanton approximations for reaction rate constant. From expression, we analyze contributions to constant in terms of minimum-action paths find that two such dominate expression. For symmetric barriers, these join together describe periodic orbit. However, asymmetric one takes an unphysically low energy dominates leading order-of-magnitude errors predictions. Nevertheless, theory remains accurate. conclude can only be obtained...

We describe a path-integral molecular dynamics implementation of our recently developed golden-rule quantum transition-state theory (GR-QTST). The method is applied to compute the reaction rate in various models electron transfer and benchmarked against exact results. demonstrate that for systems exhibiting two or more transition states, rates computed using Wolynes [P. G. Wolynes, J. Chem. Phys. 87, 6559 (1987)] can be overestimated by orders magnitude, whereas GR-QTST predictions are...
The interconnection of networks between several techno-socioeconomic sectors such as energy, transport, and communication, questions the manageability resilience digital society. System interdependencies alter fundamental dynamics that govern isolated systems, which can unexpectedly trigger catastrophic instabilities cascading failures. This paper envisions a general-purpose, yet simple prototyping self-management software systems turn system from cause instability to an opportunity for...
Quantum computing has tremendous potential to overcome some of the fundamental limitations present in classical information processing. Yet, today's technological quality and scaling prevent exploiting its full potential. based on superconducting quantum processing units (QPUs) is among most promising approaches towards practical advantage. In this article basic approach IQM Computers described covering both QPU rest full-stack computer. particular, focus a 20-qubit computer featuring Garnet...
Digital-Analog Quantum Computation (DAQC) has recently been proposed as an alternative to the standard paradigm of digital quantum computation. DAQC creates entanglement through a continuous or analog evolution whole device, rather than by applying two-qubit gates. This manuscript describes in-depth analysis extending its implementation arbitrary connectivities and performing first systematic study scaling properties. We specify for three examples algorithms, showing that except few specific...
