Searching a quantum database using noise

Efficient retrieval of information is a core operation in the world wide web, is essential for the sustainance of living organism, and is a paradigm for optimization. Quantum physics holds the promise for a quadratic speedup with respect to existing classical search algorithms. Achieving such speedup, however, requires an outstanding degree of control of the quantum dynamics of systems of large size. This implies the suppression and corrections of the errors induced by the unavoidable action of the external environment. In this talk, we will take inspiration from foraging in nature, which results from the interplay of deterministic dynamics and stochasticity, and discuss examples of quantum search dynamics emerging from the interplay between quantum coherent processes and the action of an external reservoir. We will discuss how these insights can contribute to our understanding of out-of-equilibrium dynamics in the quantum world and of the mechanisms of their stabilization, and how they could pave the way for a novel class of robust quantum algorithms.

Fluxonium superconducting circuits were originally proposed to realize highly coherent qubits. In this talk, we explain how these circuits can be used to implement and harness qutrits, by tuning their energy levels and matrix elements via an external flux bias. In particular, we investigate arrays of fluxonium qutrits, and their potential for the quantum simulation of exotic quantum matter. We identify different operational regimes, classified according to the plasmon-like versus fluxon-like nature of the qutrit excitations. Highly tunable on-site interactions are complemented by correlated single-particle hopping, pair hopping and non-local interactions, which naturally emerge and have different weights in the different regimes. We investigate the rich ground-state phase diagram of qutrit arrays and propose practical dynamical experiments to probe the different regimes. Future directions towards analogue simulation of exotic quantum matter are presented.

Qubit measurements using nonreciprocal amplifiers

High-fidelity QND qubit measurements are a cornerstone of quantum error correction schemes. In state-of-the-art superconducting quantum processors, this is achieved by combining dispersive readout with low-noise microwave measurement chains based on parametric amplifiers. However, to protect the qubits from unwanted backaction, typical systems require multiple stages of bulky magnetic circulators, a major roadblock toward scaling this approach to thousands or millions of qubits. Here I will discuss various efforts toward building amplifiers which embed directionality, and their applications to qubit measurements. In particular, I will focus on the experimental demonstration of high-fidelity, multiplexed, QND qubit measurements with a circulator-free readout chain, achieving all the requirements for scalability.
