Gate‐Tunable Floquet Weyl Photon Emission from Topological Dirac Semimetal Cd3As2

open access: yesAdvanced Materials, EarlyView.
We report experimental demonstration of Floquet band engineering in a 3D Dirac semimetal. Circularly polarized light breaks the time reversal symmetry and transforms Cd3As2 into a Floquet–Weyl phase, splitting Dirac nodes into chirality‐opposite Weyl nodes with nonzero Berry curvature.

Quantum Computing

IEEE Software, 2021
Have you ever tried to retrieve that forgotten key code for your suitcase? After one year without traveling, many of us found themselves having forgotten the combination and manually trying all permutations. The same situation, but more complex, would be to systematically try identifying that forgotten access code for an online app that you had not ...

Quantum Computability

SIAM Journal on Computing, 1997
Summary: Some theoretical and (potentially) practical aspects of quantum computing are considered. Using the tools of transcendental number theory it is demonstrated that quantum Turing machines (QTM) with rational amplitudes are sufficient to define the class of bounded error quantum polynomial time (BQP) introduced by \textit{E.

Quantum computers and quantum computations

Physics-Uspekhi, 2005
This review outlines the principles of operation of quantum computers and their elements. The theory of ideal computers that do not interact with the environment and are immune to quantum decohering processes is presented. Decohering processes in quantum computers are investigated.
