The Structure of Higher-Order Quantum Resources with an Application to Coherence
Felix Ahnefeld, Thomas Theurer, Martin B. Plenio
We develop a general framework for higher-order quantum resources that treats the resourcefulness of quantum states, channels, and supermaps (also called processes) in a unified ma…
Coherence as a resource for phase estimation
Felix Ahnefeld, Thomas Theurer, Martin B. Plenio
Quantum phase estimation is a core task in quantum technologies ranging from metrology to quantum computing, where it appears as a key subroutine in various algorithms. Here, we qu…
Single-shot entanglement manipulation of states and channels revisited
Thomas Theurer, Kun Fang, Gilad Gour
We study entanglement distillation and dilution of states and channels in the single-shot regime. With the help of a recently introduced conversion distance, we provide compact clo…
Complete Characterization of Entanglement Embezzlement
Elia Zanoni, Thomas Theurer, Gilad Gour
Using local operations and classical communication (LOCC), entanglement can be manipulated but not created. However, entanglement can be embezzled. In this work, we completely char…
Thermodynamic state convertibility is determined by qubit cooling and heating
Thomas Theurer, Elia Zanoni, Carlo Maria Scandolo +1
Thermodynamics plays an important role both in the foundations of physics and in technological applications. An operational perspective adopted in recent years is to formulate it a…
On the Role of Coherence in Shor's Algorithm
Felix Ahnefeld, Thomas Theurer, Dario Egloff +2
Shor's factoring algorithm provides a super-polynomial speed-up over all known classical factoring algorithms. Here, we address the question of which quantum properties fuel this a…
Coherence of operations and interferometry
Michele Masini, Thomas Theurer, Martin B. Plenio
Quantum coherence is one of the key features that fuels applications for which quantum mechanics exceeds the power of classical physics. This explains the considerable efforts that…
Asymptotic state transformations of continuous variable resources
Giovanni Ferrari, Ludovico Lami, Thomas Theurer +1
We study asymptotic state transformations in continuous variable quantum resource theories. In particular, we prove that monotones displaying lower semicontinuity and strong supera…
Quantifying dynamical coherence with dynamical entanglement
Thomas Theurer, Saipriya Satyajit, Martin B. Plenio
Coherent superposition and entanglement are two fundamental aspects of non-classicality. Here we provide a quantitative connection between the two on the level of operations by sho…
Experimental quantification of coherence of a tunable quantum detector
Huichao Xu, Feixiang Xu, Thomas Theurer +5
Quantum coherence is a fundamental resource that quantum technologies exploit to achieve performance beyond that of classical devices. A necessary prerequisite to achieve this adva…
When is a non-Markovian quantum process classical?
Simon Milz, Dario Egloff, Philip Taranto +4
More than a century after the inception of quantum theory, the question of which traits and phenomena are fundamentally quantum remains under debate. Here we give an answer to this…
Quantum coherence and state conversion: theory and experiment
Kang-Da Wu, Thomas Theurer, Guo-Yong Xiang +4
The resource theory of coherence studies the operational value of superpositions in quantum technologies. A key question in this theory concerns the efficiency of manipulation and…
Quantifying Operations with an Application to Coherence
Thomas Theurer, Dario Egloff, Lijian Zhang +1
To describe certain facets of non-classicality, it is necessary to quantify properties of operations instead of states. This is the case if one wants to quantify how well an operat…
Stochastic Coherence Theory for Qubits
Thomas Theurer, Alexander Streltsov, Martin B. Plenio
The resource theory of coherence studies the operational value of superpositions in quantum technologies. A key question in this theory concerns the efficiency of manipulation and…
Of Local Operations and Physical Wires
Dario Egloff, Juan Mauricio Matera, Thomas Theurer +1
In this work (multipartite) entanglement, discord and coherence are unified as different aspects of a single underlying resource theory defined through simple and operationally mea…
A resource theory of superposition
T. Theurer, N. Killoran, D. Egloff +1
The superposition principle lies at the heart of many non-classical properties of quantum mechanics. Motivated by this, we introduce a rigorous resource theory framework for the qu…
