Coherence-enhanced efficiency of feedback-driven quantum engines
A genuine feature of projective quantum measurements is that they inevitably alter the mean energy of the observed system if the measured quantity does not commute with the Hamiltonian. Compared toExpand
Electron shelving of a superconducting artificial atom
TLDR
This work establishes a resource-efficient (cavityless) alternative to cQED for controlling superconducting qubits by detecting a homodyne fluorescence signal from the cycling transition and implementing a QND readout of the qubit. Expand
Weak values, quantum trajectories, and the cavity-QED experiment on wave-particle correlation
Weak values as introduced by Aharonov, Albert, and Vaidman (AAV) are ensemble-average values for the results of weak measurements. They are interesting when the ensemble is preselected on aExpand
Scattering into one-dimensional waveguides from a coherently-driven quantum-optical system
We develop a new computational tool and framework for characterizing the scattering of photons by energy-nonconserving Hamiltonians into unidirectional (chiral) waveguides, for example, with coherentExpand
Maximal energy extraction via quantum measurement
We study the maximal amount of energy that can be extracted from a finite quantum system by means of projective measurements. For this quantity we coin the expression "metrotropy" $\mathcal{M}$, inExpand
Quantum Measurement Cooling.
TLDR
It is found that the probability that QMC occurs when the measurement basis is chosen randomly can be very large as compared to the probability of extracting energy (heat engine operation), while remaining always smaller than the most useless operation, namely, dumping heat in both baths. Expand
Maxwell's Lesser Demon: A Quantum Engine Driven by Pointer Measurements.
We discuss a self-contained spin-boson model for a measurement-driven engine, in which a demon generates work from thermal excitations of a quantum spin via measurement and feedback control. InsteadExpand
Past quantum states of a monitored system.
TLDR
The past quantum state, which, at time T, accounts for the state of a quantum system at earlier times t, is introduced, which generalizes theories of pre- and postselected quantum states to systems subject to any quantum measurement scenario, any coherent evolution, and any Markovian dissipation processes. Expand
Extracting Work from Quantum Measurement in Maxwell's Demon Engines.
TLDR
This work proposes a new type of quantum Maxwell's demon engine where work is directly extracted from the measurement channel, such that no heat bath is required and shows that in the Zeno regime of frequent measurements, memory erasure costs eventually vanish. Expand
Introduction to quantum noise, measurement, and amplification
The topic of quantum noise has become extremely timely due to the rise of quantum information physics and the resulting interchange of ideas between the condensed matter and atomic, molecular,Expand
