Fault-tolerant state preparation and injection for more efficient fine-grained quantum circuit synthesis
Berat Yenilen, Markus Müller, Manuel Rispler
Magic-state injection is a standard route to realize universal fault-tolerant quantum computation. Whereas the set of Clifford gates in combination with the non-Clifford T gate is…
Gravity-mediated entanglement via infinite-dimensional systems
Stefan L. Ludescher, Leon D. Loveridge, Thomas D. Galley +1
There has been a wave of recent interest in detecting the quantum nature of gravity with table-top experiments that witness gravitationally mediated entanglement. Central to these…
Exact numerical solution of the fully-connected classical and quantum Heisenberg spin glass
Nikita Kavokine, Markus Müller, Antoine Georges +1
We present the mean field solution of the quantum and classical Heisenberg spin glasses, using the combination of a high precision numerical solution of the Parisi full replica sym…
Spin-bounded correlations: rotation boxes within and beyond quantum theory
Albert Aloy, Thomas D. Galley, Caroline L. Jones +2
How can detector click probabilities respond to spatial rotations around a fixed axis, in any possible physical theory? Here, we give a thorough mathematical analysis of this quest…
Robustness and measurement-induced percolation of the surface code
Thomas Botzung, Michael Buchhold, Sebastian Diehl +1
We examine the robustness of a logical qubit in the planar surface code subject to 'measurement-errors', i.e., to local Pauli measurements at known positions. This yields a measure…
Quantum Superpositions of Conscious States in a Minimal Integrated Information Model
Kelvin J. McQueen, Ian T. Durham, Markus P. Mueller
Could there be quantum superpositions of conscious states, as suggested by the Wigner's friend thought experiment? Mathematical theories of consciousness, notably Integrated Inform…
Response to "The measurement postulates of quantum mechanics are not redundant"
Lluís Masanes, Thomas D. Galley, Markus P. Müller
Adrian Kent has recently presented a critique [arXiv:2307.06191] of our paper [Nat. Comms. 10, 1361 (2019)] in which he claims to refute our main result: the measurement postulates…
Theory-independent randomness generation from spatial symmetries
Caroline L. Jones, Stefan L. Ludescher, Albert Aloy +1
We demonstrate a fundamental relation between the structures of physical space and of quantum theory: the set of quantum correlations in a rotational prepare-and-measure scenario c…
Testing quantum theory by generalizing noncontextuality
Markus P. Mueller, Andrew J. P. Garner
It is a fundamental prediction of quantum theory that states of physical systems are described by complex vectors or density operators on a Hilbert space. However, many experiments…
Entanglement-asymmetry correspondence for internal quantum reference frames
Anne-Catherine de la Hamette, Stefan L. Ludescher, Markus P. Mueller
In the quantization of gauge theories and quantum gravity, it is crucial to treat reference frames such as rods or clocks not as idealized external classical relata, but as interna…
Internal quantum reference frames for finite Abelian groups
Philipp A. Hoehn, Marius Krumm, Markus P. Mueller
Employing internal quantum systems as reference frames is a crucial concept in quantum gravity, gauge theories and quantum foundations whenever external relata are unavailable. In…
Engineered dissipation induced entanglement transition in quantum spin chains: from logarithmic growth to area law
Thomas Botzung, Sebastian Diehl, Markus Müller
Recent theoretical work has shown that the competition between coherent unitary dynamics and stochastic measurements, performed by the environment, along wavefunction trajectories…
Free agency and determinism: is there a sensible definition of computational sourcehood?
Marius Krumm, Markus P. Mueller
Can free agency be compatible with determinism? Compatibilists argue that the answer is yes, and it has been suggested that the computer science principle of "computational irreduc…
Quantum Darwinism and the spreading of classical information in non-classical theories
Roberto D. Baldijao, Marius Krumm, Andrew J. P. Garner +1
Quantum Darwinism posits that the emergence of a classical reality relies on the spreading of classical information from a quantum system to many parts of its environment. But what…
Efficient and robust certification of genuine multipartite entanglement in noisy quantum error correction circuits
Andrea Rodriguez-Blanco, Alejandro Bermudez, Markus Müller +1
Ensuring the correct functioning of quantum error correction (QEC) circuits is crucial to achieve fault tolerance in realistic quantum processors subjected to noise. The first chec…
Undecidability and unpredictability: not limitations, but triumphs of science
Markus P. Mueller
It is a widespread belief that results like Gödel's incompleteness theorems or the intrinsic randomness of quantum mechanics represent fundamental limitations to humanity's strive…
Design and Experimental Performance of Local Entanglement Witness Operators
David Amaro, Markus Müller
Entanglement is a central concept in quantum information and a key resource for many quantum protocols. In this work we propose and analyze a class of entanglement witnesses that d…
General Bayesian theories and the emergence of the exclusivity principle
Giulio Chiribella, Adán Cabello, Matthias Kleinmann +1
We address the problem of reconstructing quantum theory from the perspective of an agent who makes bets about the outcomes of possible experiments. We build a general Bayesian fram…
Coherence and asymmetry cannot be broadcast
Matteo Lostaglio, Markus P. Mueller
In the presence of conservation laws, superpositions of eigenstates of the corresponding conserved quantities cannot be generated by quantum dynamics. Thus, any such coherence repr…
The measurement postulates of quantum mechanics are operationally redundant
Lluís Masanes, Thomas D. Galley, Markus P. Müller
Understanding the core content of quantum mechanics requires us to disentangle the hidden logical relationships between the postulates of this theory. Here we show that the mathema…
Von Neumann entropy from unitarity
P. Boes, J. Eisert, R. Gallego +2
The von Neumann entropy is a key quantity in quantum information theory and, roughly speaking, quantifies the amount of quantum information contained in a state when many identical…
