Predictive simulations of the dynamical response of mesoscopic devices
S. Boutin, Torsten Karzig, Tareq El Dandachi +4 more·Feb 18, 2025
As the complexity of mesoscopic quantum devices increases, simulations are becoming an invaluable tool for understanding their behavior. This is especially true for the superconductor-semiconductor heterostructures used to build Majorana-based topolo...
Benchmarking MedMNIST dataset on real quantum hardware
Gurinder Singh, Hongni Jin, Kenneth M. Merz·Feb 18, 2025
Quantum machine learning (QML) has emerged as a promising domain to leverage the computational capabilities of quantum systems to solve complex classification tasks. In this work, we present the first comprehensive QML study by benchmarking the MedMN...
Increasing the distance of topological codes with time vortex defects
Gilad Kishony, Erez Berg·Feb 17, 2025
We propose modifying topological quantum error correcting codes by incorporating space-time defects, termed ``time vortices,'' to reduce the number of physical qubits required to achieve a desired logical error rate. A time vortex is inserted by addi...
Roadmap to fault tolerant quantum computation using topological qubit arrays
D. Aasen, M. Aghaee, Zulfi Alam +179 more·Feb 17, 2025
We describe a concrete device roadmap towards a fault-tolerant quantum computing architecture based on noise-resilient, topologically protected Majorana-based qubits. Our roadmap encompasses four generations of devices: a single-qubit device that ena...
Matrix Low-dimensional Qubit Casting Based Quantum Electromagnetic Transient Network Simulation Program
Qi Lou, Yijun Xu, W. Gu·Feb 17, 2025
In modern power systems, the integration of converter-interfaced generations requires the development of electromagnetic transient network simulation programs (EMTP) that can capture rapid fluctuations. However, as the power system scales, the EMTP's...
Unitality Conditions on Subsystems in Quantum Dynamics
Anumita Mukhopadhyay, Shibdas Roy, A. K. Pati·Feb 17, 2025
It is known that non-unital noise such as the amplitude damping can sometimes increase quantum correlations, while unital noise such as the dephasing usually decreases quantum correlations. It is, therefore, important to delineate the conditions, whe...
Towards identifying possible fault-tolerant advantage of quantum linear system algorithms in terms of space, time and energy
Yue Tu, Mark Dubynskyi, Mohammadhossein Mohammadisiahroudi +5 more·Feb 16, 2025
Quantum computing, a prominent non-Von Neumann paradigm beyond Moore's law, can offer superpolynomial speedups for certain problems. Yet its advantages in efficiency for tasks like machine learning remain under investigation, and quantum noise compli...
Error-mitigated entanglement-assisted quantum process tomography
Zhihao Wu, Lingling Lao, Chengqi Zhuke +6 more·Feb 15, 2025
In the era of noisy intermediate-scale quantum computing, it is of crucial importance to verify quantum processes and extract information. Quantum process tomography is a typical approach, however, both resource-intensive and vulnerable to state prep...
Revealing the fuel of a quantum continuous measurement-based refrigerator
Cyril Elouard, Sreenath K. Manikandan, Andrew N. Jordan +1 more·Feb 14, 2025
While quantum measurements have been shown to constitute a resource for operating quantum thermal machines, the nature of the energy exchanges involved in the interaction between system and measurement apparatus is still under debate. In this work, w...
Analog Quantum Teleportation
Uesli Alushi, Simone Felicetti, Roberto Di Candia·Feb 14, 2025
Digital teleportation protocols make use of entanglement, local measurements and a classical communication channel to transfer quantum states between remote parties. We consider analog teleportation protocols, where classical communication is replace...
Constant Overhead Entanglement Distillation via Scrambling
Andi Gu, Lorenzo Leone, Kenneth Goodenough +1 more·Feb 13, 2025
High-fidelity quantum entanglement enables key quantum networking capabilities such as secure communication and distributed quantum computing, but long-distance entanglement distribution is limited by noise and loss. Entanglement distillation protoco...

Nirupam Basak, Andrew Tanggara, Ankith Mohan +2 more·Feb 13, 2025
Quantum error correction plays a critical role in enabling fault-tolerant quantum computing by protecting fragile quantum information from noise. While general-purpose quantum error correction codes are designed to address a wide range of noise types...
Bound entanglement-assisted prepare-and-measure scenarios based on four-dimensional quantum messages
Istv'an M'arton, Erika Bene, Tam'as V'ertesi·Feb 12, 2025
We present a class of linear correlation witnesses that detects bound entanglement within a three-party prepare-and-measure scenario with four-dimensional quantum messages. We relate the detection power of our witnesses for two-ququart Bloch-product-...

E. Caruccio, Simone Roncallo, V. Cimini +9 more·Feb 11, 2025
Traditional quantum metrology assesses precision using the figures of merit of continuous-valued parameter estimation. Recently, quantum digital estimation was introduced: it evaluates the performance information-theoretically by quantifying the numb...
