Adaptive variational low-rank dynamics for open quantum systems
We introduce a model-independent method for the efficient simulation of low-entropy systems, whose dynamics can be accurately described with a limited number of states. Our method leverages the time-dependent variational principle to efficiently integrate ...
Amer Physical Soc2024Ultra-high quantum coherent and scalable superconducting circuit optomechanics, from topological lattices to quantum storage
Mechanical oscillators can exhibit modes with ultra-low energy dissipation and compact form factors due to the slow velocity of acoustic waves, and are already used in applications ranging from timing to wireless filters. Over the past decade, novel ways i ...
EPFL2024Programmable frequency-bin quantum states in a nano-engineered silicon device
Frequency-bin qubits get the best of time-bin and dual-rail encodings, but require external modulators and pulse shapers to build arbitrary states. Here, instead, the authors work directly on-chip by controlling the interference of biphoton amplitudes gene ...
NATURE PORTFOLIO2023Recent advances in magnonics
Dirk Grundler, Benedetta Flebus
Magnonics is an exciting and rapidly growing field revolving around the study and manipulation of magnons, the low-lying collective excitations of magnetically ordered systems. This field has emerged in response to both fundamental physics interests and th ...
2023Creating and controlling exceptional points of non-Hermitian Hamiltonians via homodyne Lindbladian invariance
The exceptional points (EPs) of non-Hermitian Hamiltonians (NHHs) are spectral degeneracies associated with coalescing eigenvalues and eigenvectors, which are associated with remarkable dynamical properties. These EPs can be generated experimentally in ope ...
