Macroscopic quantum coherence and entanglement in mechanical systems
Benjamin Yadin, Matteo Fadel
The notion of a macroscopic quantum state must be pinned down in order to assess how well experiments probe the large-scale limits of quantum mechanics. However, the issue of quant…
Revealing hidden physical nonclassicality with nonnegative polynomials
Ties-A. Ohst, Benjamin Yadin, Birte Ostermann +3
Understanding quantum phenomena which go beyond classical concepts is a focus of modern quantum physics. Here, we show how the theory of nonnegative polynomials emerging around Hil…
Quantum speed limit for states and observables of perturbed open systems
Benjamin Yadin, Satoya Imai, Otfried Gühne
Quantum speed limits provide upper bounds on the rate with which a quantum system can move away from its initial state. Here, we provide a different kind of speed limit, describing…
Quantum-enhanced metrology with network states
Yuxiang Yang, Benjamin Yadin, Zhen-Peng Xu
Armed with quantum correlations, quantum sensors in a network have shown the potential to outclass their classical counterparts in distributed sensing tasks such as clock synchroni…
Thermodynamics of Permutation-Invariant Quantum Many-Body Systems: A Group-Theoretical Framework
Benjamin Yadin, Benjamin Morris, Kay Brandner
Quantum systems of indistinguishable particles are commonly described using the formalism of second quantisation, which relies on the assumption that any admissible quantum state m…
Multiparameter quantum metrology and mode entanglement with spatially split nonclassical spin states
Matteo Fadel, Benjamin Yadin, Yuping Mao +2
We identify the multiparameter sensitivity of split nonclassical spin states, such as spin-squeezed and Dicke states spatially distributed into several addressable modes. Analytica…
Catalytic Gaussian thermal operations
Benjamin Yadin, Hyejung H. Jee, Carlo Sparaciari +2
We examine the problem of state transformations in the framework of Gaussian thermal resource theory in the presence of catalysts. To this end, we introduce an expedient parametris…
Metrological complementarity reveals the Einstein-Podolsky-Rosen paradox
Benjamin Yadin, Matteo Fadel, Manuel Gessner
The Einstein-Podolsky-Rosen (EPR) paradox plays a fundamental role in our understanding of quantum mechanics, and is associated with the possibility of predicting the results of no…
Mixing indistinguishable systems leads to a quantum Gibbs paradox
Benjamin Yadin, Benjamin Morris, Gerardo Adesso
The classical Gibbs paradox concerns the entropy change upon mixing two gases. Whether an observer assigns an entropy increase to the process depends on their ability to distinguis…
Thermodynamic resources in continuous-variable quantum systems
Varun Narasimhachar, Syed Assad, Felix C. Binder +3
Thermodynamic resources, beyond their well-known usefulness in work extraction and other thermodynamic tasks, are often important also in tasks that are not evidently thermodynamic…
Entanglement between identical particles is a useful and consistent resource
Benjamin Morris, Benjamin Yadin, Matteo Fadel +3
The existence of fundamentally identical particles represents a foundational distinction between classical and quantum mechanics. Due to their exchange symmetry, identical particle…
Resource theories of multi-time processes: A window into quantum non-Markovianity
Graeme D. Berk, Andrew J. P. Garner, Benjamin Yadin +2
We investigate the conditions under which an uncontrollable background processes may be harnessed by an agent to perform a task that would otherwise be impossible within their oper…
Quantum correlations for anonymous metrology
A. J. Paige, Benjamin Yadin, M. S. Kim
We introduce the task of anonymous metrology, in which a physical parameter of an object may be determined without revealing the object's location. Alice and Bob share a correlated…
Coherence and quantum correlations measure sensitivity to dephasing channels
Benjamin Yadin, Pieter Bogaert, Cristian E. Susa +1
We introduce measures of quantum coherence as the speed of evolution of a system under decoherence. That is, coherence is the ability to estimate a dephasing channel, quantified by…
Witnessing quantum resource conversion within deterministic quantum computation using one pure superconducting qubit
W. Wang, J. Han, B. Yadin +9
Deterministic quantum computation with one qubit (DQC1) is iconic in highlighting that exponential quantum speedup may be achieved with negligible entanglement. Its discovery catal…
Insufficiency of avoided crossings for witnessing large-scale quantum coherence in flux qubits
Florian Fröwis, Benjamin Yadin, Nicolas Gisin
Do experiments based on superconducting loops segmented with Josephson junctions (e.g., flux qubits) show macroscopic quantum behavior in the sense of Schrödinger's cat example? Va…
Clock-work trade-off relation for coherence in quantum thermodynamics
Hyukjoon Kwon, Hyunseok Jeong, David Jennings +2
In thermodynamics, quantum coherences - superpositions between energy eigenstates - behave in distinctly nonclassical ways. Recently mathematical frameworks have emerged to account…
General measure for macroscopic quantum states beyond "dead and alive"
Pavel Sekatski, Benjamin Yadin, Marc-Olivier Renou +3
We consider the characterization of quantum superposition states beyond the pattern "dead and alive". We propose a measure that is applicable to superpositions of multiple macrosco…
Detecting metrologically useful asymmetry and entanglement by a few local measurements
Chao Zhang, Benjamin Yadin, Zhi-Bo Hou +8
Important properties of a quantum system are not directly measurable, but they can be disclosed by how fast the system changes under controlled perturbations. In particular, asymme…
Quantum processes which do not use coherence
Benjamin Yadin, Jiajun Ma, Davide Girolami +2
A major signature of quantum mechanics beyond classical physics is coherence, the existence of superposition states. The recently developed resource theory of quantum coherence all…
Converting Coherence to Quantum Correlations
Jiajun Ma, Benjamin Yadin, Davide Girolami +2
Recent results in quantum information theory characterize quantum coherence in the context of resource theories. Here we study the relation between quantum coherence and quantum di…
Witnessing multipartite entanglement by detecting asymmetry
Davide Girolami, Benjamin Yadin
The characterization of quantum coherence in the context of quantum information theory and its interplay with quantum correlations is currently subject of intense study. Coherence…
A general framework for quantum macroscopicity in terms of coherence
Benjamin Yadin, Vlatko Vedral
We propose a universal language to assess macroscopic quantumness in terms of coherence, with a set of conditions that should be satisfied by any measure of macroscopic coherence.…
Quantum macroscopicity versus distillation of macroscopic superpositions
Benjamin Yadin, Vlatko Vedral
We suggest a way to quantify a type of macroscopic entanglement via distillation of Greenberger-Horne-Zeilinger states by local operations and classical communication. We analyze h…
