The control of electrons at the level of the elementary charge e was demonstrated
experimentally already in the 1980s. Ever since, the production of an electrical current ef, or …

In this Colloquium recent advances in the field of quantum heat transport are reviewed. This
topic has been investigated theoretically for several decades, but only during the past 20 …

The tunnelling of quasiparticles across Josephson junctions in superconducting quantum
circuits is an intrinsic decoherence mechanism for qubit degrees of freedom. Understanding …

Quasiparticle excitations can compromise the performance of superconducting devices,
causing high-frequency dissipation, decoherence in Josephson qubits,,,,,, and braiding …

Recent progress on micro-and nanometer-scale manipulation has opened the possibility to
probe systems small enough that thermal fluctuations of energy and coordinate variables …

Quantum technology promises revolutionizing applications in information processing,
communications, sensing and modelling. However, efficient on-demand cooling of the …

Superconducting devices, based on the Cooper pairing of electrons, play an important role
in existing and emergent technologies, ranging from radiation detectors, to quantum …

We demonstrate radio-frequency thermometry on a micrometer-sized metallic island below
100 mK. Our device is based on a normal-metal–insulator–superconductor tunnel junction …

The parity modulation of the ground state of a superconducting island is a direct
consequence of the presence of the Cooper-pair condensate preferring an even number of …

In a superconductor, in which electrons are paired, the density of unpaired electrons should
become zero when approaching zero temperature. Therefore, radiation detectors based on …
