Asymptotic state transformations of continuous variable resources
We prove that strongly superadditive monotones can be used to bound
asymptotic state transformation rates in continuous variable resource theories.
This removes the need for asymptotic continuity, which is typically lost in
infinite-dimensional settings. We consider three applications, to the resource
theories of (I) optical nonclassicality, (II) entanglement, and (III) quantum
thermodynamics. In cases (II) and (III), the employed monotones are the
squashed entanglement and the free energy, respectively. For case (I), we
consider the measured relative entropy of nonclassicality and prove it to be
strongly superadditive. Our technique then yields computable upper bounds on
asymptotic transformation rates including those achievable under linear optical
elements. We conclude by applying our findings to the problem of cat state
manipulation.Comment: 7+34 pages, 1+5 figure

Experimental quantification of coherence of a tunable quantum detector
Quantum coherence is a fundamental resource that quantum technologies exploit
to achieve performance beyond that of classical devices. A necessary
prerequisite to achieve this advantage is the ability of measurement devices to
detect coherence from the measurement statistics. Based on a recently developed
resource theory of quantum operations, here we quantify experimentally the
ability of a typical quantum-optical detector, the weak-field homodyne
detector, to detect coherence. We derive an improved algorithm for quantum
detector tomography and apply it to reconstruct the positive-operator-valued
measures (POVMs) of the detector in different configurations. The reconstructed
POVMs are then employed to evaluate how well the detector can detect coherence
using two computable measures. As the first experimental investigation of
quantum measurements from a resource theoretical perspective, our work sheds
new light on the rigorous evaluation of the performance of a quantum
measurement apparatus
Threshold Energy Switching and Its Application to Wireless Sensing
ABSTRACT A solid state threshold energy switching device based on a relaxation oscillator is discussed in the context of a self energizing wireless pressure sensor. The study is an integral part of the design of a wireless pressure sensor for in-situ injection molding machine cavity pressure measurement and real time process control. The pressure information is measured using a piezoelectric stack and converted to a train of ultrasonic pulses, using the oscillator based threshold switching device, to a receiver outside of the mold. In this paper the threshold switching device is developed, simulated using a circuit simulation program, and validated experimentally. Its properties are discussed with reference to pressure measurement and acoustic signal transmission. INTRODUCTION It has been shown that direct cavity pressure and temperature measurement, more than any indirect method, is related to final part qualit
