We consider the problem of frequency estimation for a single bosonic field evolving under a
squeezing Hamiltonian and continuously monitored via homodyne detection. In particular …

We show that continuous quantum nondemolition (QND) measurement of an atomic
ensemble is able to improve the precision of frequency estimation even in the presence of …

Abstract Qubits incorporating Josephson Junctions are essential for developing quantum
computing devices, nevertheless, nanostructure and chemical information of the junction …

We formulate a general program for describing and analyzing continuous, differential weak,
simultaneous measurements of noncommuting observables, which focuses on describing …

We consider the evolution of a quantum simple harmonic oscillator in a general Gaussian
state under simultaneous time-continuous weak position and momentum measurements …

In contrast to a projective quantum measurement, in a weak measurement the system is only
weakly perturbed while only partial information on the measured observable is obtained. A …

We use continuous, stochastic quantum trajectories within a framework of quantum state
diffusion (QSD) to describe alternating measurements of two noncommuting observables …

We analyze the continuous operation of the nine-qubit error-correcting Bacon-Shor code
with all noncommuting gauge operators measured at the same time. The error syndromes …

A famous theorem of Hilbert from 1888 states that for given n and d, every positive
semidefinite (psd) real form of degree 2d in n variables is a sum of squares (sos) of real …
