Digital simulation of zero-temperature spontaneous symmetry breaking in a superconducting lattice processor
Chang-Kang Hu, Guixu Xie, Kasper Poulsen +11
Quantum simulators are ideal platforms to investigate quantum phenomena that are inaccessible through conventional means, such as the limited resources of classical computers to ad…
Transport and information in open quantum systems
Kasper Poulsen
With the approaching second quantum revolution, the study of quantum thermodynamics, particularly heat flow, has become even more relevant for two main reasons. First, understandin…
Heat-based circuits using quantum rectification
Kasper Poulsen, Nikolaj T. Zinner
With increased power consumption of modern computer components, heat-based circuitry has become ever more relevant due to a lower power expense to process logic bits of information…
Dark-State-Induced Heat Rectification
Kasper Poulsen, Nikolaj T. Zinner
Heat and noise control is essential for the continued development of quantum technologies. For this purpose, a particularly powerful tool is the heat rectifier, which allows for he…
Quantum Wheatstone Bridge
Kasper Poulsen, Alan C. Santos, Nikolaj T. Zinner
We propose a quantum Wheatstone bridge as a fully quantum analogue to the classical version. The bridge is a few-body boundary-driven spin chain exploiting quantum effects to gain…
Quantum Maxwell's Demon Assisted by Non-Markovian Effects
Kasper Poulsen, Marco Majland, Seth Lloyd +2
Maxwell's demon is the quintessential example of information control, which is necessary for designing quantum devices. In thermodynamics, the demon is an intelligent being who uti…
Entanglement-enhanced quantum rectification
Kasper Poulsen, Alan C. Santos, Lasse B. Kristensen +1
Quantum mechanics dictates the band-structure of materials that is essential for functional electronic components. With increased miniaturization of devices, it becomes possible to…
Giant Magnetoresistance in Boundary-Driven Spin Chains
Kasper Poulsen, Nikolaj T. Zinner
In solid state physics, giant magnetoresistance is the large change in electrical resistance due to an external magnetic field. Here we show that giant magnetoresistance is possibl…
