Environment Alignment and Redundant Record Formation in Imperfect-CNOT Quantum Darwinism
Aleksander Lasek, Paweł Horodecki
Quantum Darwinism explains objective information through redundant environmental records. Earlier work established that imperfect records can be amplified and that environment self…
Kubo-Martin-Schwinger relation for energy eigenstates of SU(2)-symmetric quantum many-body systems
Jae Dong Noh, Aleksander Lasek, Jade LeSchack +1
The fluctuation-dissipation theorem (FDT) is a fundamental result in statistical mechanics. It stipulates that, if perturbed out of equilibrium, a system responds at a rate proport…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Numerical evidence for the non-Abelian eigenstate thermalization hypothesis
Aleksander Lasek, Jae Dong Noh, Jade LeSchack +1
The eigenstate thermalization hypothesis (ETH) explains how generic quantum many-body systems thermalize internally. It implies that local operators' time-averaged expectation valu…
Noncommuting conserved charges in quantum thermodynamics and beyond
Shayan Majidy, William F. Braasch, Aleksander Lasek +3
Thermodynamic systems typically conserve quantities ("charges") such as energy and particle number. The charges are often assumed implicitly to commute with each other. Yet quantum…
Pulse-controlled qubit in semiconductor double quantum dots
Aleksander Lasek, Hugo V. Lepage, Kexin Zhang +2
We present a numerically-optimized multipulse framework for the quantum control of a single-electron charge qubit. Our framework defines a set of pulse sequences, necessary for the…
Non-Abelian symmetry can increase entanglement entropy
Shayan Majidy, Aleksander Lasek, David A. Huse +1
The pillars of quantum theory include entanglement and operators' failure to commute. The Page curve quantifies the bipartite entanglement of a many-body system in a random pure st…
Experimental observation of thermalization with noncommuting charges
Florian Kranzl, Aleksander Lasek, Manoj K. Joshi +4
Quantum simulators have recently enabled experimental observations of quantum many-body systems' internal thermalization. Often, the global energy and particle number are conserved…
Engineering single donor detectors in doped silicon
A. A. Lasek, C. H. W. Barnes, T. Ferrus
We demonstrate the possibility of engineering a single donor transistor directly from a phosphorous doped quantum dot by making use of the intrinsic glassy behaviour of the structu…
Entanglement generation via power-of-SWAP operations between dynamic electron-spin qubits
Hugo V. Lepage, Aleksander A. Lasek, David R. M. Arvidsson-Shukur +1
Surface acoustic waves (SAWs) can create moving quantum dots in piezoelectric materials. Here we show how electron-spin qubits located on dynamic quantum dots can be entangled. Pre…
Quantum Advantage in Postselected Metrology
David R. M. Arvidsson-Shukur, Nicole Yunger Halpern, Hugo V. Lepage +3
We show that postselection offers a nonclassical advantage in metrology. In every parameter-estimation experiment, the final measurement or the postprocessing incurs some cost. Pos…
