Convergence of repeated QND measurements and the wave function collapse
QND measurement the wave function collapse Quantum Physics
2011/7/26
Abstract: Motivated by recent experiments on quantum trapped fields, we give a rigorous proof that repeated indirect quantum non-demolition (QND) measurements converge to the collapse of the wave func...
Feasible optical weak measurements of complementary observables via a single Hamiltonian
optical weak measurements Hamiltonian optical weak measurements
2011/9/15
We show that the process of three-wave mixing in a non-linear crystal (such as employed in down conversion processes) can be used for versatile weak measurements. That is the crystal field interaction...
A new response mode of quantum systems, repeatedly interrogated by quantum probe particles,is introduced: quantum entrainment. Quantum entrainment is shown to arise in an interferometric scheme for th...
What is credible and what is incredible in the measurements of the Casimir force
What is credible what is incredible the measurements Casimir force
2010/11/4
We comment on progress in measurements of the Casimir force and discuss what is the actual reliability of different experiments. In this connection a more rigorous approach to the usage of such concep...
Quantum measurement of a system can change its mean energy, as well as entropy. A selective measurement (classical or quantum) can be used as a "Maxwell's demon" to power a single-temperature heat eng...
Short Multi-Prover Quantum Proofs for SAT without Entangled Measurements
Entangled Measurements Short Multi-Prover Quantum
2010/11/8
BellQMA protocols are a subclass of multi-prover quantum Merlin-Arthur protocols in which the verifier is restricted to perform nonadaptive,unentangled measurements on the quantum states received from...
Simulation studies and spectroscopic measurements of a position sensitive detector based on pixelated CdTe crystals
spectroscopic measurements position sensitive detector pixelated CdTe crystals
2010/11/16
Simulation studies and spectroscopic measurements are presented regarding the development of a pixel multilayer CdTe detector under development in the context of the COCAE project. The instrument wil...
Evolution of surname distribution under gender-equality measurements
Evolution of surname distribution gender-equality measurements
2010/11/16
We consider a model for the evolution of the surnames distribution under a gender-equality measurement presently discussed in the Spanish parliament (the children take the surname of the father or th...
Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
Estimation of compact binary coalescense rates short gamma-ray redshift measurements
2010/12/21
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...
Timing Measurements of the Relativistic Binary Pulsar PSR B1913+16
Measurements Relativistic Binary Pulsar PSR B1913+16
2010/12/21
We present results of more than three decades of timing measurements of the rst known binary pulsar, PSR B1913+16. Like most other pulsars, its rotational behavior over such long time scales is signi...

A mini-review of measurements of inclusive semileptonic B ! Xcℓν and radiative B ! Xsγ decays
is presented.
Exact Pointer Properties for Quantum System Projector Measurements with Application to Weak Measurements and Their Accuracy
Exact Pointer Properties Quantum System Projector Measurements Application Measurements Accuracy
2010/11/5
Exact pointer states are obtained for projection operator measurements performed upon pre-selected (PS) and upon pre- and post-selected (PPS) quantum systems. These states are used to provide simple e...
We show that the phase shift of 2 is crucial for the phase space translation covariance of the measured high-amplitude limit observable in eight-port homodyne detection. However, for an arbitrary pha...
Device-Independent Quantum Key Distribution with Commuting Measurements
Device-Independent Quantum Key Distribution ommuting Measurements
2010/10/19
We consider quantum key distribution in the device-independent scenario, i.e., where the
legitimate parties do not know (or trust) the exact specification of their apparatus. We show
how secure key ...
Ultimate quantum bounds on mass measurements with a nano-mechanical oscillator
Ultimate quantum bounds mass measurements nano-mechanical oscillator
2010/10/21
Nano-mechanical resonators have a large potential as sensors of very small adsorbed masses,
down to the atomic level and beyond. Here I establish the fundamental lower bound on the mass
that can be ...
