Compressive gate set tomography
Raphael Brieger, Ingo Roth, Martin Kliesch
Flexible characterization techniques that identify and quantify experimental imperfections under realistic assumptions are crucial for the development of quantum computers. Gate se…
Engineering Strong Beamsplitter Interaction between Bosonic Modes via Quantum Optimal Control Theory
Daniel Basilewitsch, Yaxing Zhang, S. M. Girvin +1
In continuous-variable quantum computing with qubits encoded in the infinite-dimensional Hilbert space of bosonic modes, it is a difficult task to realize strong and on-demand inte…
Secure Anonymous Conferencing in Quantum Networks
Federico Grasselli, Gláucia Murta, Jarn de Jong +4
Users of quantum networks can securely communicate via so-called (quantum) conference key agreement --making their identities publicly known. In certain circumstances, however, com…
Lie algebra for rotational subsystems of a driven asymmetric top
Eugenio Pozzoli, Monika Leibscher, Mario Sigalotti +2
We present an analytical approach to construct the Lie algebra of finite-dimensional subsystems of the driven asymmetric top rotor. Each rotational level is degenerate due to the i…
Simulating quantum repeater strategies for multiple satellites
Julius Wallnöfer, Frederik Hahn, Mustafa Gündoğan +5
A global quantum repeater network involving satellite-based links is likely to have advantages over fiber-based networks in terms of long-distance communication, since the photon l…
Estimating gate-set properties from random sequences
J. Helsen, M. Ioannou, J. Kitzinger +4
With quantum computing devices increasing in scale and complexity, there is a growing need for tools that obtain precise diagnostic information about quantum operations. However, c…
Resource theory of quantum uncomplexity
Nicole Yunger Halpern, Naga B. T. Kothakonda, Jonas Haferkamp +3
Quantum complexity is emerging as a key property of many-body systems, including black holes, topological materials, and early quantum computers. A state's complexity quantifies th…
Rate limits in quantum networks with lossy repeaters
Riccardo Laurenza, Nathan Walk, Jens Eisert +1
The derivation of ultimate limits to communication over certain quantum repeater networks have provided extremely valuable benchmarks for assessing near-term quantum communication…
Ideal Quantum Tele-amplification up to a Selected Energy Cut-off using Linear Optics
Joshua J. Guanzon, Matthew S. Winnel, Austin P. Lund +1
We introduce a linear optical technique that can implement ideal quantum tele-amplification up to the Fock state, where can be any positive integer. Here tele-a…
Boundary theories of critical matchgate tensor networks
Alexander Jahn, Marek Gluza, Charlotte Verhoeven +2
Key aspects of the AdS/CFT correspondence can be captured in terms of tensor network models on hyperbolic lattices. For tensors fulfilling the matchgate constraint, these have prev…
Gottesman-Kitaev-Preskill codes: A lattice perspective
Jonathan Conrad, Jens Eisert, Francesco Arzani
We examine general Gottesman-Kitaev-Preskill (GKP) codes for continuous-variable quantum error correction, including concatenated GKP codes, through the lens of lattice theory, in…
Resource-efficient dissipative entanglement of two trapped-ion qubits
Daniel C. Cole, Stephen D. Erickson, Giorgio Zarantonello +7
We demonstrate a simplified method for dissipative generation of an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher f…
Identifying optimal cycles in quantum thermal machines with reinforcement-learning
Paolo Andrea Erdman, Frank Noé
The optimal control of open quantum systems is a challenging task but has a key role in improving existing quantum information processing technologies. We introduce a general frame…
Robustly learning the Hamiltonian dynamics of a superconducting quantum processor
Dominik Hangleiter, Ingo Roth, Jonas Fuksa +2
The required precision to perform quantum simulations beyond the capabilities of classical computers imposes major experimental and theoretical challenges. The key to solving these…
Mechanisms for the emergence of Gaussian correlations
Marek Gluza, Thomas Schweigler, Mohammadamin Tajik +8
We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system underg…
Relativistic Bohmian trajectories of photons via weak measurements
Joshua Foo, Estelle Asmodelle, Austin P. Lund +1
Bohmian mechanics is a nonlocal hidden-variable interpretation of quantum theory which predicts that particles follow deterministic trajectories in spacetime. Historically, the stu…
What can unitary sequences tell us about multi-time physics?
Gregory A. L. White, Felix A. Pollock, Lloyd C. L. Hollenberg +2
Multi-time quantum processes are endowed with the same richness as multipartite states, including temporal entanglement and exotic causal structures. However, experimentally probin…
Reservoir-engineering shortcuts to adiabaticity
Raphaël Menu, Josias Langbehn, Christiane P. Koch +1
We propose a protocol that achieves fast adiabatic transfer between two orthogonal states of a qubit by coupling with an ancilla. The qubit undergoes Landau-Zener dynamics, whereas…
Single-component gradient rules for variational quantum algorithms
Thomas Hubregtsen, Frederik Wilde, Shozab Qasim +1
Many near-term quantum computing algorithms are conceived as variational quantum algorithms, in which parameterized quantum circuits are optimized in a hybrid quantum-classical set…
Quantifying Quantumness of Channels Without Entanglement
Huan-Yu Ku, Josef Kadlec, Antonín Černoch +8
Quantum channels breaking entanglement, incompatibility, or nonlocality are defined as such because they are not useful for entanglement-based, one-sided device-independent, or dev…
Linear growth of quantum circuit complexity
Jonas Haferkamp, Philippe Faist, Naga B. T. Kothakonda +2
Quantifying quantum states' complexity is a key problem in various subfields of science, from quantum computing to black-hole physics. We prove a prominent conjecture by Brown and…
