@inproceedings{Yanik2022ThermodynamicsOQ, title={Thermodynamics of Quantum Measurement and the Demon's Arrow of Time}, author={Kagan Yanik and Burhanuddin Bhandari and Sreenath K. Manikandan and Andrew N. Jordan}, year={2022} }

We discuss the thermodynamic aspects of a single qubit based device, powered by weak quantum measurements, and feedback controlled by a quantum Maxwell’s demon. We discuss both discrete and time-continuous operation of the measurement based device at ﬁnite temperature of the reservoir. In the discrete example where a demon acquires information via discrete weak measurements, we ﬁnd that the thermodynamic variables including the heat exchanged, extractable work, and the entropy produced are…

The role of quantum measurement in stochastic thermodynamics

- Physics
- 2016

This article sets up a new formalism to investigate stochastic thermodynamics in the quantum regime, where stochasticity and irreversibility primarily come from quantum measurement. In the absence of…

Time reversal symmetry of generalized quantum measurements with past and future boundary conditions

We expand the time reversal symmetry arguments of quantum mechanics, originally proposed by Wigner in the context of unitary dynamics, to contain situations including generalized measurements for…

Quantum measurement arrow of time and fluctuation relations for measuring spin of ultracold atoms

- PhysicsNature communications
- 2021

This work experimentally demonstrates a striking parallel between the statistical irreversibility of wavefunction collapse and the arrow of time problem in the weak measurement of the quantum spin of an atomic cloud and provides evidence for absolute irreversability for measurements performed on a quantum many-body entangled wavefunction.

Extracting Work from Quantum Measurement in Maxwell's Demon Engines.

- PhysicsPhysical review letters
- 2017

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.

Characterizing a Statistical Arrow of Time in Quantum Measurement Dynamics.

- PhysicsPhysical review letters
- 2019

This work compares the statistics of individual trajectories to ensemble properties showing that the measurement dynamics obeys both detailed and integral fluctuation theorems, thus establishing the consistency between microscopic and macroscopic measurement dynamics.

Stabilizing Rabi oscillations in a superconducting qubit using quantum feedback

- PhysicsNature
- 2012

This work demonstrates quantum feedback control by inhibiting the decay of Rabi oscillations, allowing them to persist indefinitely and permits the active suppression of decoherence and enables a method of quantum error correction based on weak continuous measurements.

Coherence and measurement in quantum thermodynamics

- PhysicsScientific reports
- 2016

Information processing tasks, the so-called projections, that can only be formulated within the framework of quantum mechanics are identified and it is shown that the physical realisation of such projections can come with a non-trivial thermodynamic work only for quantum states with coherences.

We present a uniﬁed approach to study continuous measurement based quantum thermal machines in static as well as adiabatically driven systems. We investigate both steady state and transient dynamics…

Quantum-mechanical Maxwell’s demon

- Physics
- 1997

A Maxwell's demon is a device that gets information and trades it in for thermodynamic advantage, in apparent (but not actual) contradiction to the second law of thermodynamics. Quantum-mechanical…

Heat and Work Along Individual Trajectories of a Quantum Bit.

- PhysicsPhysical review letters
- 2020

A near quantum limited detector is used to experimentally track individual quantum state trajectories of a driven qubit formed by the hybridization of a waveguide cavity and a transmon circuit, and the first law of thermodynamics for an open quantum system is verified.
