Detection and manipulation of Majorana fermions in circuit QED [PDF]

, 2013
Motivated by recent experimental progress towards the measurement and manipulation of Majorana fermions with superconducting circuits, we propose a device interfacing Majorana fermions with circuit quantum electrodynamics.

Theoretical Investigations of Experimental Gravitation [PDF]

, 1979
This thesis has two basic themes: the investigation of new experiments which can be used to test relativistic gravity, and the investigation of new technologies and new experimental techniques which can be applied to make gravitational wave astronomy ...

A general approach to backaction-evading receivers with magnetomechanical and electromechanical sensors

, 2023
Today\u27s mechanical sensors are capable of detecting extremely weak perturbations while operating near the standard quantum limit. However, further improvements can be made in both sensitivity and bandwidth when we reduce the noise originating from the

Leggett-Garg inequality with a kicked quantum pump

, 2006
A kicked quantum nondemolition measurement is introduced, where a qubit is weakly measured by pumping current. Measurement statistics are derived for weak measurements combined with single-qubit unitary operations.

Measurement-device-independent quantum key distribution

, 2012
How to remove detector side channel attacks has been a notoriously hard problem in quantum cryptography. Here, we propose a simple solution to this problem-measurement-device-independent quantum key distribution (QKD).

Quantum simulations of macrorealism violation via the quantum nondemolition measurement protocol

The Leggett-Garg inequalities have been proposed to identify the quantum behavior of a system; specifically, the violation of macrorealism. They are usually implemented by performing two sequential measurements on quantum systems, calculating the ...

Nonisochronous Oscillations in Piezoelectric Nanomechanical Resonators [PDF]

, 2012
Nanoelectromechanical systems (NEMS) have proven an excellent test bed for exploring nonlinear dynamics due to short decay times, weak nonlinearities, and large quality factors.

Photonic spatial Bell-state analysis for robust quantum secure direct communication using quantum dot-cavity systems

, 2013
Recently, experiments showed that the spatial-mode states of entangled photons are more robust than their polarization-mode states in quantum communications.

Topics in LIGO-Related Physics: Interferometric Speed Meters and Tidal Work [PDF]

, 2003
In the quest to develop viable designs for third-generation optical interferometric gravitational-wave detectors, one strategy is to monitor the relative momentum or speed of the test-mass mirrors, rather than monitoring their relative position.
