During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

Quantum information processing relies on the precise control of non-classical states in the
presence of many uncontrolled environmental degrees of freedom. The interactions …

Detecting single–photon level signals—carriers of both classical and quantum information—
is particularly challenging for low-energy microwave frequency excitations. Here we …

In quantum physics, measurements can fundamentally yield discrete and random results.
Emblematic of this feature is Bohr's 1913 proposal of quantum jumps between two discrete …

The control of individual quantum systems is now a reality in a variety of physical settings.
Feedback control is an important class of control methods because of its ability to reduce the …

We study the quantum evolution of a non-Hermitian qubit realized as a submanifold of a
dissipative superconducting transmon circuit. Real-time tuning of the system parameters to …

We present an overview of recent advances in the study of energy dynamics and
mechanisms for energy conversion in qubit systems with special focus on realizations in …

This article sets up a new formalism to investigate stochastic thermodynamics in the
quantum regime, where stochasticity and irreversibility primarily come from quantum …

Many superconducting qubit systems use the dispersive interaction between the qubit and a
coupled harmonic resonator to perform quantum state measurement. Previous works have …

Quantum materials exhibit a wide array of exotic phenomena and practically useful
properties. A better understanding of these materials can provide deeper insights into …
