Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

One of the most widely known building blocks of modern physics is Heisenberg's
indeterminacy principle. Among the different statements of this fundamental property of the …

Achieving effectively adiabatic dynamics is a ubiquitous goal in almost all areas of quantum
physics. Here, we study the speed with which a quantum system can be driven when …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Time-asymmetric state-evolution properties while encircling an exceptional point are
presently of great interest in search of new principles for controlling atomic and optical …

We demonstrate that it is possible to implement a quantum perceptron with a sigmoid
activation function as an efficient, reversible many-body unitary operation. When inserted in …

Quantum control methods, like rapid adiabatic passage, stimulated Raman adiabatic
passage, shortcuts to adiabaticity and optimal control, have become an integral part of …

We propose and experimentally demonstrate a high-performance polarization splitter-rotator
based on the lithium niobate-on-insulator platform, consisting of an adiabatic taper, an …

A short and broadband silicon asymmetric Y-junction two-mode (de) multiplexer is proposed
and simulated. An adiabaticity parameter suitable for high index-contrast silicon waveguides …

A systematic approach to design robust control protocols against the influence of different
types of noise is introduced. We present control schemes which protect the decay of the …
