Ultrastrong coupling dynamics with a transmon qubit
New Journal of Physics, 2017 The interaction of light and matter is often described by the exchange of single excitations. When the coupling strength is a significant fraction of the system frequencies, the number of excitations are no longer preserved and that simple picture breaks

Complexity, Volume 2020, Issue 1, 2020., 2020 Hydraulic drive mode enables legged robots to have excellent characteristics, such as greater power‐to‐weight ratios, higher load capacities, and faster response speeds than other robots. Nowadays, highly integrated valve‐controlled cylinder, called the hydraulic drive unit (HDU), is employed to drive the joints of these robots. However, there are some

New Journal of Physics, 2016 Nonclassical states of macroscopic objects are promising for ultrasensitive metrology as well as testing quantum mechanics. In this work, we investigate dissipative mechanical quantum state engineering in an optically levitated nanodiamond.

Deterministic quantum state transfer from an electronic charge qubit to a photonic polarization qubit [PDF]
, 2006 Building on an earlier proposal for the production of polarization-entangled microwaves by means of intraband transitions in a pair of quantum dots, we show how this device can be used to transfer an unknown single-qubit state from electronic charge to ...

Entanglement condition via su(2) and su(1,1) algebra using Schr{\"o}dinger-Robertson uncertainty relation [PDF]
, 2007 The Schr{\"o}dinger-Robertson inequality generally provides a stronger bound on the product of uncertainties for two noncommuting observables than the Heisenberg uncertainty relation, and as such, it can yield a stricter separability condition in ...

Directly comparing entanglement-enhancing non-Gaussian operations
New Journal of Physics, 2015 Single-photon-level non-Gaussian operations—photon addition, photon subtraction, and their coherent superposition—are powerful tools with which to increase entanglement in continuous-variable optical states.

Observation of triply coincident nonlinearities in periodically poled KTiOPO4 [PDF]
, 2005 We report the simultaneous quasi-phase-matching of all three possible nonlinearities for propagation along the X axis of periodocally poled (PP) KTiOPO4 (KTP) for second-harmonic generation of 745 nm pulsed light from 1490nm subpicosecond pulses in a ...

Resonant cavity photon creation via the dynamical Casimir effect
, 2004 Motivated by a recent proposal for an experimental verification of the dynamical Casimir effect, the macroscopic electromagnetic field within a perfect cavity containing a thin slab with a time-dependent dielectric permittivity is quantized in terms of ...

Projective measurement in nuclear magnetic resonance [PDF]
, 2006 It is demonstrated that nuclear magnetic resonance experiments using pseudopure spin states can give possible outcomes of projective quantum measurement and probabilities of such outcomes.
