Coherent spin–photon coupling using a resonant exchange qubit
Electron spins hold great promise for quantum computation because of their long coherence times. Long-distance coherent coupling of spins is a crucial step towards quantum information processing withExpand

Experimental realization of a Szilard engine with a single electron
Significance A Maxwell demon makes use of information to convert thermal energy of a reservoir into work. A quantitative example is a thought experiment known as a Szilard engine, which uses one bitExpand

Strong Coupling Cavity QED with Gate-Defined Double Quantum Dots Enabled by a High Impedance Resonator
The strong coupling limit of cavity quantum electrodynamics (QED) implies the capability of a matter-like quantum system to coherently transform an individual excitation into a single photon within aExpand

Microwave Photon-Mediated Interactions between Semiconductor Qubits
The realization of a coherent interface between distant charge or spin qubits in semiconductor quantum dots is an open challenge for quantum information processing. Here we demonstrate both resonantExpand

Experimental observation of the role of mutual information in the nonequilibrium dynamics of a Maxwell demon.
We validate experimentally a fluctuation relation known as generalized Jarzynski equality governing the work distribution in a feedback-controlled system. The feedback control is performed on aExpand

Distribution of entropy production in a single-electron box
The fluctuation relations are a central concept in thermodynamics at the microscopic scale. These relations are experimentally verified by measuring the entropy production in a single-electron boxExpand

Distribution of current fluctuations in a bistable conductor
We measure the full distribution of current fluctuations in a single-electron transistor with a controllable bistability. The conductance switches randomly between two levels due to the tunneling ofExpand

Automated tuning of double quantum dots into specific charge states using neural networks
TLDR
We introduce an algorithm driven by machine learning that uses a small number of coarse-grained measurements as its input and tunes the quantum dot system into a pre-selected charge state. Expand

Experimental realization of a Coulomb blockade refrigerator
We present an experimental realization of a Coulomb blockade refrigerator (CBR) based on a single - electron transistor (SET). In the present structure, the SET island is interrupted by aExpand
