The Impact of Quantum Memory Quality on Entanglement Assisted Communication
Stephen Diadamo, Janis Noetzel·Jul 29, 2023
This work explores entanglement-assisted communication, where quantum entanglement resources enable the transmission of classical information at an enhanced rate. We consider a scenario where entanglement is distributed ahead of time based on network...
Two-Qubit Gate Set Tomography with Fewer Circuits
K. Rudinger, Corey I. Ostrove, Stefan K. Seritan +4 more·Jul 28, 2023
Gate set tomography (GST) is a self-consistent and highly accurate method for the tomographic reconstruction of a quantum information processor's quantum logic operations, including gates, state preparations, and measurements. However, GST's experime...
Spectral properties of two superconducting artificial atoms coupled to a resonator in the ultrastrong coupling regime
A. Tomonaga, R. Stassi, H. Mukai +3 more·Jul 28, 2023
We experimentally investigate a superconducting circuit composed of two flux qubits ultrastrongly coupled to a common LC resonator. Owing to the large anharmonicity of the flux qubits, the system can be described well by a generalized Dicke Hamiltoni...
Dissipation-enabled bosonic Hamiltonian learning via new information-propagation bounds
Tim Mobus, Andreas Bluhm, Matthias C. Caro +2 more·Jul 27, 2023
Reliable quantum technology requires knowledge of the dynamics governing the underlying system. This problem of characterizing and benchmarking quantum devices or experiments in continuous time is referred to as the Hamiltonian learning problem. In c...
Decoding algorithms for surface codes
Antonio deMarti iOlius, Patricio Fuentes, Rom'an Or'us +2 more·Jul 27, 2023
Quantum technologies have the potential to solve certain computationally hard problems with polynomial or super-polynomial speedups when compared to classical methods. Unfortunately, the unstable nature of quantum information makes it prone to errors...
Simulation of quantum algorithms using classical probabilistic bits and circuits
D. Yavuz, A. Yadav·Jul 26, 2023
We discuss a new approach to simulate quantum algorithms using classical probabilistic bits and circuits. Each qubit (a two-level quantum system) is initially mapped to a vector in an eight dimensional probability space (equivalently, to a classical ...
String amplitudes and mutual information in confining backgrounds: the partonic behavior
M. Ghodrati·Jul 25, 2023
In the background of several holographic confining backgrounds, we present the connections between the behaviors of string scattering amplitudes and mutual information. We lay down the analogies between the logarithmic branch cut behavior of the stri...
Energy preserving evolutions over Bosonic systems
Paul Gondolf, Tim Möbus, C. Rouzé·Jul 25, 2023
The exponential convergence to invariant subspaces of quantum Markov semigroups plays a crucial role in quantum information theory. One such example is in bosonic error correction schemes, where dissipation is used to drive states back to the code-sp...
Measurement-Free Fault-Tolerant Quantum Error Correction in Near-Term Devices
Sascha Heußen, David F. Locher, M. Muller·Jul 25, 2023
Logical qubits can be protected from decoherence by performing QEC cycles repeatedly. Algorithms for fault-tolerant QEC must be compiled to the specific hardware platform under consideration in order to practically realize a quantum memory that opera...
MORE: Measurement and Correlation Based Variational Quantum Circuit for Multi-Classification
Jindi Wu, Tianjie Hu, Qun Li·Jul 21, 2023
Quantum computing has shown considerable promise for compute-intensive tasks in recent years. For instance, classification tasks based on quantum neural networks (QNN) have garnered significant interest from researchers and have been evaluated in var...
Scalable tensor-network error mitigation for near-term quantum computing
Sergei E. Filippov, Matea Leahy, M. Rossi +1 more·Jul 21, 2023
Until fault-tolerance becomes implementable at scale, quantum computing will heavily rely on noise mitigation techniques. While methods such as zero noise extrapolation with probabilistic error amplification (ZNE-PEA) and probabilistic error cancella...
Special features of the Weyl–Heisenberg Bell basis imply unusual entanglement structure of Bell-diagonal states
Christopher Popp, B. Hiesmayr·Jul 20, 2023
Bell states are of crucial importance for entanglement based methods in quantum information science. Typically, a standard construction of a complete orthonormal Bell-basis by Weyl–Heisenberg operators is considered. We show that the group structure ...

We propose a new model of quantum computation comprised of low-weight measurement sequences that simultaneously encode logical information, enable error correction, and apply logical gates. These measurement sequences constitute a new class of quantu...
A Cryogenic Memristive Neural Decoder for Fault-tolerant Quantum Error Correction
Fr'ed'eric Marcotte, Pierre-Antoine Mouny, Victor Yon +6 more·Jul 18, 2023
Neural decoders for quantum error correction (QEC) rely on neural networks to classify syndromes extracted from error correction codes and find appropriate recovery operators to protect logical information against errors. Its ability to adapt to hard...
Dissipative phase transitions and passive error correction
Yu-Jie Liu, S. Lieu·Jul 18, 2023
We classify different ways to passively protect classical and quantum information, i.e. we do not allow for syndrome measurements, in the context of local Lindblad models for spin systems. Within this family of models, we suggest that passive error c...
