The Transient Counting Statistics of Autonomous Quantum Clocks
Oscar Arandes, Sreenath K. Manikandan
At the heart of every atomic clock is a quantum coherent emitter, the laser, that could in principle be treated autonomously. While their frequency or phase stability is typically…
Correlated Quantum Sensing at the Seemingly Classical Limit
K. P. Athulya, Sreenath K. Manikandan
It is a difficult task to detect the indivisible quanta of weakly interacting radiation fields, and even more challenging to probe their quantum statistics. Nevertheless, if barely…
Quantum Sensing with Joint Emitter-Fluorescence Measurements
Yuliya Bilinskaya, Sreenath K. Manikandan
We present an analytically tractable model of a driven quantum harmonic emitter, such as an oscillating charged dipole, emitting radiation via resonance fluorescence. With this mod…
Signatures of coherent initial ensembles on all work moments
Pranay Nayak, Sreenath K. Manikandan, Tan Van Vu +1
Standard treatments of quantum work using projective energy measurements erase initial coherence and alter the dynamics, thereby failing to capture the thermodynamic effects of coh…
Detector Correlations and Null Tests of the Coherent State Hypothesis
Sreenath K. Manikandan, Frank Wilczek
We discuss the statistics of correlations between two resonant detectors. We show that this allows simple null tests of the coherent state hypothesis, free of vacuum (quantum) nois…
Revealing the fuel of a quantum continuous measurement-based refrigerator
Cyril Elouard, Sreenath K. Manikandan, Andrew N. Jordan +1
While quantum measurements have been shown to constitute a resource for operating quantum thermal machines, the nature of the energy exchanges involved in the interaction between s…
Quantum Measurement Induced Radiative Processes in Continuously Monitored Optical Environments
Eldhose Benny, Sreenath K. Manikandan
We investigate the emission characteristics of a measurement-driven quantum emitter in a continuously monitored optical environment. The quantum emitter is stimulated by observing…
Testing the Coherent State Description of Radiation Fields
Sreenath K. Manikandan, Frank Wilczek
We propose simple quantitative criteria, based on counting statistics in resonant harmonic detectors, that probe the quantum mechanical character of radiation fields. They provide,…
Detecting single gravitons with quantum sensing
Germain Tobar, Sreenath K. Manikandan, Thomas Beitel +1
The quantization of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. But their detection has so far been considered…
Autonomous quantum clocks using athermal resources
Sreenath K. Manikandan
Here we explore the possibility of precise time-keeping in quantum systems using athermal resources. We show that quantum measurement engineered reservoirs can be used as athermal…
Thermodynamics of Quantum Measurement and the Demon's Arrow of Time
Kagan Yanik, Bibek Bhandari, Sreenath K. Manikandan +1
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 dis…
Optimal quantum parametric feedback cooling
Sreenath K. Manikandan, Sofia Qvarfort
We propose an optimal protocol using phase-preserving quantum measurements and phase-dependent modulations of the trapping potential at parametric resonance to cool a quantum oscil…
Efficiently Fuelling a Quantum Engine with Incompatible Measurements
Sreenath K. Manikandan, Cyril Elouard, Kater W. Murch +2
We propose a quantum harmonic oscillator measurement engine fueled by simultaneous quantum measurements of the non-commuting position and momentum quadratures of the quantum oscill…
Quantum erasing the memory of Wigner's friend
Cyril Elouard, Philippe Lewalle, Sreenath K. Manikandan +3
The Wigner's friend paradox concerns one of the most puzzling problems of quantum mechanics: the consistent description of multiple nested observers. Recently, a variation of Wigne…
Wave-Particle Duality Controlled by Single-Photon Self-Entanglement
X. -F. Qian, K. Konthasinghe, S. K. Manikandan +3
We experimentally observe that quantum duality of a single photon is controlled by its self-entanglement through a three-way quantum coherence identity . Here V, D,…

Philippe Lewalle, Cyril Elouard, Sreenath K. Manikandan +3
We consider protocols to generate quantum entanglement between two remote qubits, through joint time-continuous detection of their spontaneous emission. We demonstrate that schemes…
Measuring Fluorescence to Track a Quantum Emitter's State: A Theory Review
Philippe Lewalle, Sreenath K. Manikandan, Cyril Elouard +1
We review the continuous monitoring of a qubit through its spontaneous emission, at an introductory level. Contemporary experiments have been able to collect the fluorescence of an…
Turning off quantum duality
X. -F. Qian, K. Konthasinghe, K. Manikandan +3
We provide the first experimental confirmation of a three-way quantum coherence identity possessed by single pure-state photons. Our experimental results demonstrate that tradition…
Fluctuation Theorems for Continuous Quantum Measurement and Absolute Irreversibility
Sreenath K. Manikandan, Cyril Elouard, Andrew N. Jordan
Fluctuation theorems are relations constraining the out-of-equilibrium fluctuations of thermodynamic quantities like the entropy production that were initially introduced for class…
Time reversal symmetry of generalized quantum measurements with past and future boundary conditions
Sreenath K. Manikandan, Andrew N. Jordan
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 m…
The qubit reveals a qubit-cavity system
Sreenath K. Manikandan, Vinayak Jagadish, Anil Shaji
We show that the coupling between a qubit and a single mode cavity can be estimated from the process tomography data for the qubit alone. All the parameters of the coupling Hamilto…
