Quantum control of molecular rotation [PDF]
Reviews of Modern Physics, 2018 The angular momentum of molecules, or, equivalently, their rotation in three-dimensional space, is ideally suited for quantum control. Molecular angular momentum is naturally quantized, time evolution is governed by a well-known Hamiltonian with only a ...

Nanoscale Research Letters, 2019 Negative photoconductivity effect has been observed in the Au/WO3 nanowire/Au devices in a high humidity environment, which might be attributed to the accumulation of H+ ions on the surface of WO3 nanowire.

Achieving robust and high-fidelity quantum control via spectral phase optimization
, 2017 Achieving high-fidelity control of quantum systems is of fundamental importance in physics, chemistry and quantum information sciences. However, the successful implementation of a high-fidelity quantum control scheme also requires robustness against ...

Shadow of a Schwarzschild black hole surrounded by a Bach–Weyl ring
European Physical Journal C: Particles and Fields, 2020 We have studied the shadows of a Schwarzschild black hole surrounded by a Bach–Weyl ring through the backward ray-tracing method. The presence of Bach–Weyl ring leads to that the photon dynamical system is non-integrable and then chaos would appear in ...

European Physical Journal C: Particles and Fields, 2021 We have studied polarized image of a Schwarzschild black hole with an equatorial thin accretion disk as photon couples to Weyl tensor. The birefringence of photon originating from the coupling affect the black hole shadow, the thin disk pattern and its ...

Quantum speed limits: from Heisenberg’s uncertainty principle to optimal quantum control [PDF]
, 2017 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 full quantum mechanical nature of physical reality, the uncertainty relation for ...

Reinforcement Learning in Different Phases of Quantum Control [PDF]
Physical Review X, 2017 The ability to prepare a physical system in a desired quantum state is central to many areas of physics such as nuclear magnetic resonance, cold atoms, and quantum computing.

Coherent control of quasi-degenerate stationary-like states via multiple resonances
Scientific Reports, 2017 We use three bosons held in a depth-tilt combined-modulated double-well to study coherent control of quantum transitions between quasi-degenerate stationary-like states (QDSLSs) with the same quasienergy.

Dynamical Generation of Noiseless Quantum Subsystems [PDF]
, 2000 We present control schemes for open quantum systems that combine decoupling and universal control methods with coding procedures. By exploiting a general algebraic approach, we show how appropriate encodings of quantum states result in obtaining ...
