Enhanced optical trapping via structured scattering
Michael A Taylor, Muhammad Waleed, Alexander B Stilgoe +2
Interferometry can completely redirect light, providing the potential for strong and controllable optical forces. However, small particles do not naturally act like interferometric…
Quantum correlations overcome the photodamage limits of light microscopy
Catxere A. Casacio, Lars S. Madsen, Alex Terrasson +5
State-of-the-art microscopes use intense lasers that can severely disturb biological processes, function and viability. This introduces hard limits on performance that only quantum…
Evanescent single-molecule biosensing with quantum limited precision
N. P. Mauranyapin, L. S. Madsen, M. A. Taylor +2
Sensors that are able to detect and track single unlabelled biomolecules are an important tool both to understand biomolecular dynamics and interactions at nanoscale, and for medic…
Subdiffraction-limited quantum imaging within a living cell
Michael A. Taylor, Jiri Janousek, Vincent Daria +4
We report both sub-diffraction-limited quantum metrology and quantum enhanced spatial resolution for the first time in a biological context. Nanoparticles are tracked with quantum…
Optical lock-in particle tracking in optical tweezers
Michael A Taylor, Joachim Knittel, Warwick P Bowen
We demonstrate a lock-in particle tracking scheme in optical tweezers based on stroboscopic modulation of an illuminating optical field. This scheme is found to evade low frequency…
Fundamental constraints on particle tracking with optical tweezers
Michael A. Taylor, Joachim Knittel, Warwick P. Bowen
A general quantum limit to the sensitivity of particle position measurements is derived following the simple principle of the Heisenberg microscope. The value of this limit is calc…
Sagnac Interferometer Enhanced Particle Tracking in Optical Tweezers
M. A. Taylor, J. Knittel, M. T. L. Hsu +2
A setup is proposed to enhance tracking of very small particles, by using optical tweezers embedded within a Sagnac interferometer. The achievable signal-to-noise ratio is shown to…
