Composable Verification in the Circuit-Model via Magic-Blindness
Sami Abdul Sater, Harold Ollivier·Jan 12, 2026
As quantum computing machines move towards the utility regime, it is essential that users are able to verify their delegated quantum computations with security guarantees that are (i) robust to noise (ii) composable with other secure protocols and (i...
Tackling Heterogeneity in Quantum Federated Learning: An Integrated Sporadic-Personalized Approach
Ratun Rahman, Shaba Shaon, Dinh C. Nguyen·Jan 11, 2026
Quantum federated learning (QFL) emerges as a powerful technique that combines quantum computing with federated learning to efficiently process complex data across distributed quantum devices while ensuring data privacy in quantum networks. Despite r...

Achieving full control of a Bose-Einstein condensate can have valuable applications in metrology, quantum information processing, and quantum condensed matter physics. We propose protocols to simultaneously control the internal (related to its pseudo...
Counter-diabatic driving for fast spin control in a two-electron double quantum dot
Yue Ban, Xi Chen·Jan 11, 2026
The techniques of shortcuts to adiabaticity have been proposed to accelerate the "slow" adiabatic processes in various quantum systems with the applications in quantum information processing. In this paper, we study the counter-diabatic driving for f...
Quantum Circuit-Based Adaptation for Credit Risk Analysis
Halima Giovanna Ahmad, Alessandro Sarno, Mehdi El Bakraoui +12 more·Jan 11, 2026
Noisy and Intermediate-Scale Quantum, or NISQ, processors are sensitive to noise, prone to quantum decoherence, and are not yet capable of continuous quantum error correction for fault-tolerant quantum computation. Hence, quantum algorithms designed ...
Cancelling second order frequency shifts in Ge hole spin qubits via bichromatic control
Xiangjun Tan, Zhanning Wang, Wenkai Bai +1 more·Jan 11, 2026
Germanium quantum dot hole spin qubits are compatible with fully electrical control and are progressing toward multi-qubit operations. However, their coherence is limited by charge noise and driving field induced frequency shifts, and the resulting e...
Noise-Resistant Feature-Aware Attack Detection Using Quantum Machine Learning
Chao Ding, Shi Wang, Jingtao Sun +3 more·Jan 11, 2026
Continuous-variable quantum key distribution (CV-QKD) is a quantum communication technology that offers an unconditional security guarantee. However, the practical deployment of CV-QKD systems remains vulnerable to various quantum attacks. In this pa...

Sinchan Snigdha Rej, Snigdhadev Ray, Bimalendu Deb·Jan 10, 2026
Quantum computation (QC) and digital quantum simulation (DQS) essentially require two- or multi-qubit controlled-NOT or -phase gates. We propose an alternative pathway for QC and DQS using a three-qubit parity gate in a Rydberg atom array. The basic ...
Informationally Complete Distributed Metrology Without a Shared Reference Frame
Hua-Qing Xu, Gong-Chu Li, Xu-Song Hong +6 more·Jan 10, 2026
In quantum information processing, implementing arbitrary preparations and measurements on qubits necessitates precise information to identify a specific reference frame (RF). In space quantum communication and sensing, where a shared RF is absent, t...

Sabrina Yue Wang, Raul A. Santos·Jan 9, 2026
Noise and decoherence are ubiquitous in the dynamics of quantum systems coupled to an external environment. In the regime where environmental correlations decay rapidly, the evolution of a subsytem is well described by a Lindblad quantum master equat...
